CAIS  Application Interactive Services provide the means to create links between an application GUI viewer and the packages which are used to manage selection and presentation. The tools AIS defined in order to do this include different sorts of entities: both the selectable viewable objects themselves and the context and attribute managers to define their selection and display. To orient the user as he works in a modeling environment, views and selections must be comprehensible. There must be several different sorts of selectable and viewable object defined. These must also be interactive, that is, connecting graphic representation and the underlying reference geometry. These entities are called Interactive Objects, and are divided into four types: 
CAIS_AngleDimension  Angle dimension. Can be constructed: 
CAIS_Animation  Class represents single animation. It is defined with: 
CAIS_AnimationCamera  Camera animation 
CAIS_AnimationObject  Animation defining object transformation 
CAIS_AnimationProgress  Structure defining current animation progress 
CAIS_AnimationTimer  Auxiliary class defining the animation timer 
CAIS_AttributeFilter  Selects Interactive Objects, which have the desired width or color. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it has the required color and width attributes. If the object returns true in each case, it is kept. If not, it is rejected. This filter is used only in an open local context. In the Collector viewer, you can only locate Interactive Objects, which answer positively to the filters, which are in position when a local context is open 
CAIS_Axis  Locates the x, y and z axes in an Interactive Object. These are used to orient it correctly in presentations from different viewpoints, or to construct a revolved shape, for example, from one of the axes. Conversely, an axis can be created to build a revolved shape and then situated relative to one of the axes of the view 
CAIS_BadEdgeFilter  A Class 
CAIS_C0RegularityFilter

CAIS_ConcentricRelation  A framework to define a constraint by a relation of concentricity between two or more interactive datums. The display of this constraint is also defined. A plane is used to create an axis along which the relation of concentricity can be extended 
CAIS_ConnectedInteractive  Creates an arbitrary located instance of another Interactive Object, which serves as a reference. This allows you to use the Connected Interactive Object without having to recalculate presentation, selection or graphic structure. These are deduced from your reference object. The relation between the connected interactive object and its source is generally one of geometric transformation. AIS_ConnectedInteractive class supports selection mode 0 for any InteractiveObject and all standard modes if its reference based on AIS_Shape. Descendants may redefine ComputeSelection() though. Also ConnectedInteractive will handle HLR if its reference based on AIS_Shape 
CAIS_DiameterDimension  Diameter dimension. Can be constructued: 
►CAIS_Dimension  AIS_Dimension is a base class for 2D presentations of linear (length, diameter, radius) and angular dimensions 
CAIS_DimensionOwner  The owner is the entity which makes it possible to link the sensitive primitives and the reference shapes that you want to detect. It stocks the various pieces of information which make it possible to find objects. An owner has a priority which you can modulate, so as to make one entity more selectable than another. You might want to make edges more selectable than faces, for example. In that case, you could attribute sa higher priority to the one compared to the other. An edge, could have priority 5, for example, and a face, priority 4. The default priority is 5 
CAIS_EllipseRadiusDimension  Computes geometry ( basis curve and plane of dimension) for input shape aShape from TopoDS Root class for MinRadiusDimension and MaxRadiusDimension 
CAIS_EqualDistanceRelation  A framework to display equivalent distances between shapes and a given plane. The distance is the length of a projection from the shape to the plane. These distances are used to compare shapes by this vector alone 
CAIS_EqualRadiusRelation  
CAIS_ExclusionFilter  A framework to reject or to accept only objects of given types and/or signatures. Objects are stored, and the stored objects  along with the flag settings  are used to define the filter. Objects to be filtered are compared with the stored objects added to the filter, and are accepted or rejected according to the exclusion flag setting 
CAIS_FixRelation  Constructs and manages a constraint by a fixed relation between two or more interactive datums. This constraint is represented by a wire from a shape  point, vertex, or edge  in the first datum and a corresponding shape in the second. Warning: This relation is not bound with any kind of parametric constraint : it represents the "status" of an parametric object 
CAIS_GlobalStatus  Stores information about objects in graphic context: 
CAIS_GraphicTool  
CAIS_IdenticRelation  Constructs a constraint by a relation of identity between two or more datums figuring in shape Interactive Objects 
CAIS_InteractiveContext  The Interactive Context allows you to manage graphic behavior and selection of Interactive Objects in one or more viewers. Class methods make this highly transparent. It is essential to remember that an Interactive Object which is already known by the Interactive Context must be modified using Context methods. You can only directly call the methods available for an Interactive Object if it has not been loaded into an Interactive Context. You must distinguish two states in the Interactive Context: 
CAIS_InteractiveObject  Defines a class of objects with display and selection services. Entities which are visualized and selected are Interactive Objects. You can make use of classes of standard Interactive Objects for which all necessary methods have already been programmed, or you can implement your own classes of Interactive Objects. Specific attributes of entities such as arrow aspect for dimensions must be loaded in a Drawer. This Drawer is then applied to the Interactive Object in view. There are four types of Interactive Object in AIS: the construction element or Datum, the Relation, which includes both dimensions and constraints, the Object, and finally, when the object is of an unknown type, the None type. Inside these categories, a signature, or index, provides the possibility of additional characterization. By default, the Interactive Object has a None type and a signature of 0. If you want to give a particular type and signature to your interactive object, you must redefine the methods, Signature and Type. Warning In the case of attribute methods, methods for standard attributes are virtual. They must be redefined by the inheriting classes. Setcolor for a point and Setcolor for a plane, for example, do not affect the same attributes in the Drawer 
CAIS_LengthDimension  Length dimension. Can be constructued: 
CAIS_Line  Constructs line datums to be used in construction of composite shapes 
CAIS_LocalContext  Defines a specific context for selection. It becomes possible to: 
CAIS_LocalStatus  Stored Info about temporary objects 
►CAIS_Manipulator  Interactive object class to manipulate local transformation of another interactive object or a group of objects via mouse. It manages three types of manipulations in 3D space: 
CAIS_ManipulatorOwner  Entity owner for selection management of AIS_Manipulator object 
CAIS_MaxRadiusDimension  Ellipse Max radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset)) 
CAIS_MidPointRelation  Presentation of equal distance to point myMidPoint 
CAIS_MinRadiusDimension  – Ellipse Min radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset))

CAIS_PlaneTrihedron  To construct a selectable 2d axis system in a 3d drawing. This can be placed anywhere in the 3d system, and provides a coordinate system for drawing curves and shapes in a plane. There are 3 selection modes: 
CAIS_Point  Constructs point datums to be used in construction of composite shapes. The datum is displayed as the plus marker + 
CAIS_PointCloud  Interactive object for set of points. The presentation supports two display modes: 
CAIS_RadiusDimension  Radius dimension. Can be constructued: 
CAIS_Relation  One of the four types of interactive object in AIS,comprising dimensions and constraints. Serves as the abstract class for the seven relation classes as well as the seven dimension classes. The statuses available for relations between shapes are as follows: 
CAIS_RubberBand  Presentation for drawing rubber band selection. It supports rectangle and polygonal selection. It is constructed in 2d overlay. Default configaration is built without filling. For rectangle selection use SetRectangle() method. For polygonal selection use AddPoint() and GetPoints() methods 
CAIS_Selection  Class holding the list of selected owners 
CAIS_Shape  A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes  vertices, edges, faces etc  in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient  both HLR and nonHLR  of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object 
CAIS_SignatureFilter  Selects Interactive Objects through their signatures and types. The signature provides an additional characterization of an object's type, and takes the form of an index. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it has the desired signature. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is only used in an open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning Some signatures have already been used by standard objects delivered in AIS. These include: 
CAIS_SymmetricRelation  A framework to display constraints of symmetricity between two or more datum Interactive Objects. A plane serves as the axis of symmetry between the shapes of which the datums are parts 
CAIS_TangentRelation  A framework to display tangency constraints between two or more Interactive Objects of the datum type. The datums are normally faces or edges 
CAIS_TextLabel  Presentation of the text 
CAIS_TexturedShape  This class allows to map textures on shapes. Presentations modes AIS_WireFrame (0) and AIS_Shaded (1) behave in the same manner as in AIS_Shape, whilst new modes 2 (bounding box) and 3 (texture mapping) extends it functionality 
CAIS_Triangulation  Interactive object that draws data from Poly_Triangulation, optionally with colors associated with each triangulation vertex. For maximum efficiency colors are represented as 32bit integers instead of classic Quantity_Color values. Interactive selection of triangles and vertices is not yet implemented 
CAIS_Trihedron  Create a selectable trihedron there are 4 modes of selection : mode = 0 to select trihedron ,priority = 1 mode = 1 to select its origin ,priority = 5 mode = 2 to select its axis ,priority = 3 mode = 3 to select its planes ,priority = 2 a trihedron has 1 origin, 3 axes and 3 planes. Warning For the presentation of trihedra, the default unit of length is the millimeter, and the default value for the representation of axes is 10. To modify these dimensions, you must temporarily recover the Drawer. From inside it, you take the aspect in which the values for length are stocked. For trihedra, this is FirstAxisLength from Prs3d_DatumAspect(). Change the values inside this Aspect and recalculate the presentation. If you want to use extended selection modes, different than 0, you should take care of removing of the shapes from the interactive context that has been computed for selection; it might be necessary when you change selection mode. You can use methods Axis, Point, Plane to retrieve the shapes 
CAIS_TypeFilter  Selects Interactive Objects through their types. The filter questions each Interactive Object in local context to determine whether it has an nonnull owner, and if so, whether it is of the desired type. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. A filter for type specifies a choice of type out of a range at any level enumerated for type or kind. The choice could be for kind of interactive object, of dimension, of unit, or type of axis, plane or attribute. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is used in both Neutral Point and open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning When you close a local context, all temporary interactive objects are deleted, all selection modes concerning the context are cancelled, and all content filters are emptied

CBRepExtrema_SelfIntersection  Tool class for detection of selfsections in the given shape. This class is based on BRepExtrema_OverlapTool and thus uses shape tessellation to detect incorrect mesh fragments (pairs of overlapped triangles belonging to different faces). Thus, a result depends critically on the quality of mesh generator (e.g., BREP mesh is not always a good choice, because it can contain gaps between adjacent face triangulations, which may not share vertices on common edge; thus false overlap can be detected). As a result, this tool can be used for relatively fast approximated test which provides subset of potentially overlapped faces 
CBRepExtrema_ShapeProximity  Tool class for shape proximity detection. For two given shapes and given tolerance (offset from the mesh) the algorithm allows to determine whether or not they are overlapped. The algorithm input consists of any shapes which can be decomposed into individual faces (used as basic shape elements). High performance is achieved through the use of existing triangulation of faces. So poly triangulation (with the desired deflection) should already be built. Note that solution is approximate (and corresponds to the deflection used for triangulation)

CBRepFeat  BRepFeat is necessary for the creation and manipulation of both form and mechanical features in a Boundary Representation framework. Form features can be depressions or protrusions and include the following types: 
CBRepFeat_Builder  Provides a basic tool to implement features topological operations. The main goal of the algorithm is to perform the result of the operation according to the kept parts of the tool. Input data: a) DS; b) The kept parts of the tool; If the map of the kept parts of the tool is not filled boolean operation of the given type will be performed; c) Operation required. Steps: a) Fill myShapes, myRemoved maps; b) Rebuild edges and faces; c) Build images of the object; d) Build the result of the operation. Result: Result shape of the operation required 
CBRepFeat_Form  Provides general functions to build form features. Form features can be depressions or protrusions and include the following types: 
CBRepFeat_Gluer  One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which  or up to which  matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. Glueing uses wires or edges of a face in the basis shape. These are to become a part of the feature. They are first cut out and then projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion features can be constructed 
CBRepFeat_MakeCylindricalHole  Provides a tool to make cylindrical holes on a shape 
CBRepFeat_MakeDPrism  Describes functions to build draft prism topologies from basis shape surfaces. These can be depressions or protrusions. The semantics of draft prism feature creation is based on the construction of shapes: 
CBRepFeat_MakeLinearForm  Builds a rib or a groove along a developable, planar surface. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be symmetrical  on one side of the contour  or dissymmetrical  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however, in case of mechanical features. Here they include extrusion: 
CBRepFeat_MakePipe  Constructs compound shapes with pipe features. These can be depressions or protrusions. The semantics of pipe feature creation is based on the construction of shapes: 
CBRepFeat_MakePrism  Describes functions to build prism features. These can be depressions or protrusions. The semantics of prism feature creation is based on the construction of shapes: 
CBRepFeat_MakeRevol  Describes functions to build revolved shells from basis shapes 
CBRepFeat_MakeRevolutionForm  MakeRevolutionForm Generates a surface of revolution in the feature as it slides along a revolved face in the basis shape. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral  on one side of the contour  or bilateral  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion: 
CBRepFeat_RibSlot  Provides functions to build mechanical features. Mechanical features include ribs  protrusions and grooves (or slots)  depressions along planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral  on one side of the contour  or bilateral  on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion: 
CBRepFeat_SplitShape  One of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which  or up to which  matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. In BRepFeat, the semantics of local operations define features constructed from a contour or a part of the basis shape referred to as the tool. In a SplitShape object, wires or edges of a face in the basis shape to be used as a part of the feature are cut out and projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion or depression features can be constructed

The "first parameter" gives the "start point" of the bounded curve, and the "last parameter" gives the "end point" of the bounded curve. The length of a bounded curve is finite. The Geom2d package provides three concrete classes of bounded curves:

The coordinate system is the local coordinate system of the circle. The orientation (direct or indirect) of the local coordinate system gives an explicit orientation to the circle, determining the direction in which the parameter increases along the circle.

The Geom2d package provides four specific classes of conics: Geom2d_Circle, Geom2d_Ellipse, Geom2d_Hyperbola and Geom2d_Parabola. A conic is positioned in the plane with a coordinate system (gp_Ax22d object), where the origin is the center of the conic (or the apex in case of a parabola).

CGeom2d_OffsetCurve  This class implements the basis services for the creation, edition, modification and evaluation of planar offset curve. The offset curve is obtained by offsetting by distance along the normal to a basis curve defined in 2D space. The offset curve in this package can be a self intersecting curve even if the basis curve does not selfintersect. The self intersecting portions are not deleted at the construction time. An offset curve is a curve at constant distance (Offset) from a basis curve and the offset curve takes its parametrization from the basis curve. The Offset curve is in the direction of the normal to the basis curve N. The distance offset may be positive or negative to indicate the preferred side of the curve : . distance offset >0 => the curve is in the direction of N . distance offset >0 => the curve is in the direction of  N On the Offset curve : Value(u) = BasisCurve.Value(U) + (Offset * (T ^ Z)) / T ^ Z where T is the tangent vector to the basis curve and Z the direction of the normal vector to the plane of the curve, N = T ^ Z defines the offset direction and should not have null length

CGeom2d_Transformation  The class Transformation allows to create Translation, Rotation, Symmetry, Scaling and complex transformations obtained by combination of the previous elementary transformations. The Transformation class can also be used to construct complex transformations by combining these elementary transformations. However, these transformations can never change the type of an object. For example, the projection transformation can change a circle into an ellipse, and therefore change the real type of the object. Such a transformation is forbidden in this environment and cannot be a Geom2d_Transformation. The transformation can be represented as follow :

Thus, it computes the start point and end point of perpendiculars common to the two curves (an intersection point is not an extremum except where the two curves are tangential at this point). Solutions consist of pairs of points, and an extremum is considered to be a segment joining the two points of a solution. An ExtremaCurveCurve object provides a framework for:

The curve will than be only C1 The curve is defined by a table of points through which it passes, and if required by a parallel table of reals which gives the value of the parameter of each point through which the resulting BSpline curve passes, and by vectors tangential to these points.

CGeom2dConvert_BSplineCurveKnotSplitting  An algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree  Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot.

CGeom_SurfaceOfLinearExtrusion  Describes a surface of linear extrusion ("extruded surface"), e.g. a generalized cylinder. Such a surface is obtained by sweeping a curve (called the "extruded curve" or "basis") in a given direction (referred to as the "direction of extrusion" and defined by a unit vector). The u parameter is along the extruded curve. The v parameter is along the direction of extrusion. The parameter range for the u parameter is defined by the reference curve. The parameter range for the v parameter is ]  infinity, + infinity [. The position of the curve gives the origin of the v parameter. The surface is "CN" in the v parametric direction. The form of a surface of linear extrusion is generally a ruled surface (GeomAbs_RuledForm). It can be: 
CGeom_SurfaceOfRevolution  Describes a surface of revolution (revolved surface). Such a surface is obtained by rotating a curve (called the "meridian") through a complete revolution about an axis (referred to as the "axis of revolution"). The curve and the axis must be in the same plane (the "reference plane" of the surface). Rotation around the axis of revolution in the trigonometric sense defines the u parametric direction. So the u parameter is an angle, and its origin is given by the position of the meridian on the surface. The parametric range for the u parameter is: [ 0, 2.*Pi ] The v parameter is that of the meridian. Note: A surface of revolution is built from a copy of the original meridian. As a result the original meridian is not modified when the surface is modified. The form of a surface of revolution is typically a general revolution surface (GeomAbs_RevolutionForm). It can be:

CGeomAdaptor_SurfaceOfRevolution  This class defines a complete surface of revolution. The surface is obtained by rotating a curve a complete revolution about an axis. The curve and the axis must be in the same plane. If the curve and the axis are not in the same plane it is always possible to be in the previous case after a cylindrical projection of the curve in a referenced plane. For a complete surface of revolution the parametric range is 0 <= U <= 2*PI. – The parametric range for V is defined with the revolved curve. The origin of the U parametrization is given by the position of the revolved curve (reference). The direction of the revolution axis defines the positive sense of rotation (trigonometric sense) corresponding to the increasing of the parametric value U. The derivatives are always defined for the u direction. For the v direction the definition of the derivatives depends on the degree of continuity of the referenced curve

CGeomConvert_BSplineCurveKnotSplitting  An algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree  Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot. It is possible to compute the arcs which correspond to this splitting using the global function SplitBSplineCurve provided by the package GeomConvert.

CGeomConvert_BSplineSurfaceKnotSplitting  An algorithm to determine isoparametric curves along which a BSpline surface should be split in order to obtain patches of the same continuity. The continuity order is given at the construction time. It is possible to compute the surface patches corresponding to the splitting with the method of package SplitBSplineSurface. For a Bspline surface the discontinuities are localised at the knot values. Between two knots values the Bspline is infinitely continuously differentiable. For each parametric direction at a knot of range index the continuity in this direction is equal to : Degree  Mult (Index) where Degree is the degree of the basis Bspline functions and Mult the multiplicity of the knot of range Index in the given direction. If for your computation you need to have Bspline surface with a minima of continuity it can be interesting to know between which knot values, a Bspline patch, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the surface, to obtain patches with a constant continuity given at the construction time. If you just want to compute the local derivatives on the surface you don't need to create the BSpline patches, you can use the functions LocalD1, LocalD2, LocalD3, LocalDN of the class BSplineSurface from package Geom

By default, the point mass is equal to 1 and the mass of a system composed of N points is equal to N. Warning A framework of this sort provides functions to handle sets of points easily. But, like any GProp_GProps object, by using the Add function, it can theoretically bring together the computed global properties and those of a system more complex than a set of points . The mass of each point and the density of each component of the composed system must be coherent. Note that this coherence cannot be checked.

These axes are the principal axes of inertia. Their origin is coincident with the center of mass of the system. The associated moments are called the principal moments of inertia. This sort of presentation object is created, filled and returned by the function PrincipalProperties for any GProp_GProps object, and can be queried to access the result. Note: The system whose principal properties of inertia are returned by this framework is referred to as the current system. The current system, however, is retained neither by this presentation framework nor by the GProp_GProps object which activates it

CHLRAlgo  In order to have the precision required in industrial design, drawings need to offer the possibility of removing lines, which are hidden in a given projection. To do this, the Hidden Line Removal component provides two algorithms: HLRBRep_Algo and HLRBRep_PolyAlgo. These algorithms remove or indicate lines hidden by surfaces. For a given projection, they calculate a set of lines characteristic of the object being represented. They are also used in conjunction with extraction utilities, which reconstruct a new, simplified shape from a selection of calculation results. This new shape is made up of edges, which represent the lines of the visualized shape in a plane. This plane is the projection plane. HLRBRep_Algo takes into account the shape itself. HLRBRep_PolyAlgo works with a polyhedral simplification of the shape. When you use HLRBRep_Algo, you obtain an exact result, whereas, when you use HLRBRep_PolyAlgo, you reduce computation time but obtain polygonal segments

CIFSelect  Gives tools to manage Selecting a group of Entities processed by an Interface, for instance to divide up an original Model (from a File) to several smaller ones They use description of an Interface Model as a graph 
CIFSelect_Act  Act gives a simple way to define and add functions to be ran from a SessionPilot, as follows : 
CIFSelect_Activator  Defines the general frame for working with a SessionPilot. Each Activator treats a set of Commands. Commands are given as alphanumeric strings. They can be of two main forms : 
CIFSelect_AppliedModifiers  This class allows to memorize and access to the modifiers which are to be applied to a file. To each modifier, is bound a list of integers (optionnal) : if this list is absent, the modifier applies to all the file. Else, it applies to the entities designated by these numbers in the produced file

CIFSelect_ContextWrite  This class gathers various informations used by File Modifiers apart from the writer object, which is specific of the norm and of the physical format 
CIFSelect_Dispatch  This class allows to describe how a set of Entities has to be dispatched into resulting Packets : a Packet is a subset of the initial set of entities 
CIFSelect_DispGlobal  A DispGlobal gathers all the input Entities into only one global Packet 
CIFSelect_DispPerCount  A DispPerCount gathers all the input Entities into one or several Packets, each containing a defined count of Entity This count is a Parameter of the DispPerCount, given as an IntParam, thus allowing external control of its Value 
CIFSelect_DispPerFiles  A DispPerFiles produces a determined count of Packets from the input Entities. It divides, as equally as possible, the input list into a count of files. This count is the parameter of the DispPerFiles. If the input list has less than this count, of course there will be one packet per input entity. This count is a Parameter of the DispPerFiles, given as an IntParam, thus allowing external control of its Value 
CIFSelect_DispPerOne  A DispPerOne gathers all the input Entities into as many Packets as there Root Entities from the Final Selection, that is, one Packet per Entity 
CIFSelect_DispPerSignature  A DispPerSignature sorts input Entities according to a Signature : it works with a SignCounter to do this

CIFSelect_Functions  Functions gives access to all the actions which can be commanded with the resources provided by IFSelect : especially WorkSession and various types of Selections and Dispatches 
CIFSelect_GeneralModifier  This class gives a frame for Actions which modify the effect of a Dispatch, i.e. : By Selections and Dispatches, an original Model can be splitted into one or more "target" Models : these Models contain Entities copied from the original one (that is, a part of it). Basically, these dispatched Entities are copied as identical to their original counterparts. Also the copied Models reproduce the Header of the original one 
CIFSelect_GraphCounter  A GraphCounter computes values to be sorted with the help of a Graph. I.E. not from a Signature 
CIFSelect_IntParam  This class simply allows to access an Integer value through a Handle, as a String can be (by using HString).

Thus, parameters of a Selection or a Dispatch (according its type) can be controlled directly from the ShareOut which contains them 
CIFSelect_ListEditor  A ListEditor is an auxiliary operator for Editor/EditForm I.E. it works on parameter values expressed as strings 
CIFSelect_ModelCopier  This class performs the Copy operations involved by the description of a ShareOut (evaluated by a ShareOutResult) plus, if there are, the Modifications on the results, with the help of Modifiers.

CIFSelect_Modifier  This class gives a frame for Actions which can work globally on a File once completely defined (i.e. afterwards) 
CIFSelect_ModifReorder  This modifier reorders a whole model from its roots, i.e. according to <rootlast> status, it considers each of its roots, then it orders all its shared entities at any level, the result begins by the lower level entities ... ends by the roots 
CIFSelect_PacketList  This class gives a simple way to return then consult a list of packets, determined from the content of a Model, by various criteria 
CIFSelect_ParamEditor  A ParamEditor gives access for edition to a list of TypedValue (i.e. of Static too) Its definition is made of the TypedValue to edit themselves, and can add some constants, which can then be displayed but not changed (for instance, system name, processor version ...) 
CIFSelect_SelectAnyList  A SelectAnyList kind Selection selects a List of an Entity, as well as this Entity contains some. A List contains subentities as one per Item, or several (for instance if an Entity binds couples of subentities, each item is one of these couples). Remark that only Entities are taken into account (neither Reals, nor Strings, etc...) 
CIFSelect_SelectAnyType  A SelectAnyType sorts the Entities of which the Type is Kind of a given Type : this Type for Match is specific of each class of SelectAnyType 
CIFSelect_SelectBase  SelectBase works directly from an InterfaceModel : it is the first base for other Selections

CIFSelect_SelectEntityNumber  A SelectEntityNumber gets in an InterfaceModel (through a Graph), the Entity which has a specified Number (its rank of adding into the Model) : there can be zero (if none) or one. The Number is not directly defined as an Integer, but as a Parameter, which can be externally controled 
CIFSelect_SelectErrorEntities  A SelectErrorEntities sorts the Entities which are qualified as "Error" (their Type has not been recognized) during reading a File. This does not concern Entities which are syntactically correct, but with incorrect data (for integrity constraints) 
CIFSelect_SelectExplore  A SelectExplore determines from an input list of Entities, a list obtained by a way of exploration. This implies the possibility of recursive exploration : the output list is itself reused as input, etc... Examples : Shared Entities, can be considered at one level (immediate shared) or more, or max level 
CIFSelect_SelectExtract  A SelectExtract determines a list of Entities from an Input Selection, as a sublist of the Input Result It works by applying a sort criterium on each Entity of the Input. This criterium can be applied Direct to Pick Items (default case) or Reverse to Remove Item

CIFSelect_SelectIncorrectEntities  A SelectIncorrectEntities sorts the Entities which have been noted as Incorrect in the Graph of the Session (flag "Incorrect") It can find a result only if ComputeCheck has formerly been called on the WorkSession. Else, its result will be empty 
CIFSelect_SelectInList  A SelectInList kind Selection selects a List of an Entity, which is composed of single Entities To know the list on which to work, SelectInList has two deferred methods : NbItems (inherited from SelectAnyList) and ListedEntity (which gives an item as an Entity) which must be defined to get a List in an Entity of the required Type (and consider that list is empty if Entity has not required Type) 
CIFSelect_SelectIntersection  A SelectIntersection filters the Entities issued from several other Selections as Intersection of results : "AND" operator 
CIFSelect_Selection  A Selection allows to define a set of Interface Entities.

CIFSelect_SelectModelEntities  A SelectModelEntities gets all the Entities of an InterfaceModel 
CIFSelect_SelectModelRoots  A SelectModelRoots gets all the Root Entities of an InterfaceModel. Remember that a "Root Entity" is defined as having no Sharing Entity (if there is a Loop between Entities, none of them can be a "Root")

CIFSelect_SelectRootComps  A SelectRootComps sorts the Entities which are part of Strong Componants, local roots of a set of Entities : they can be Single Componants (containing one Entity) or Cycles This class gives a more secure result than SelectRoots (which considers only Single Componants) but is longer to work : it can be used when there can be or there are cycles in a Model For each cycle, one Entity is given arbitrarily Reject works as for SelectRoots : Strong Componants defined in the input list which are not local roots are given 
CIFSelect_SelectRoots  A SelectRoots sorts the Entities which are local roots of a set of Entities (not shared by other Entities inside this set, even if they are shared by other Entities outside it)

CIFSelect_SelectSignature  A SelectSignature sorts the Entities on a Signature Matching. The signature to match is given at creation time. Also, the required match is given at creation time : exact (IsEqual) or contains (the Type's Name must contain the criterium Text) 
CIFSelect_SelectSignedShared  In the graph, explore the Shareds of the input entities, until it encounters some which match a given Signature (for a limited level, filters the returned list) By default, fitted for any level 
CIFSelect_SelectSignedSharing  In the graph, explore the sharings of the input entities, until it encounters some which match a given Signature (for a limited level, filters the returned list) By default, fitted for any level 
CIFSelect_SelectSuite  A SelectSuite can describe a suite of SelectDeduct as a unique one : in other words, it can be seen as a "macro selection" 
CIFSelect_SelectType  A SelectType keeps or rejects Entities of which the Type is Kind of a given Cdl Type 
CIFSelect_SelectUnion  A SelectUnion cumulates the Entities issued from several other Selections (union of results : "OR" operator)

CIFSelect_SessionFile  A SessionFile is intended to manage access between a WorkSession and an Ascii Form, to be considered as a Dump. It allows to write the File from the WorkSession, and later read the File to the WorkSession, by keeping required descriptions (such as dependances) 
CIFSelect_SessionPilot  A SessionPilot is intended to make easier the use of a WorkSession. It receives commands, under alphanumeric form, then calls a library of Activators to interprete and run them 
CIFSelect_ShareOut  This class gathers the informations required to produce one or several file(s) from the content of an InterfaceModel (passing through the creation of intermediate Models) 
CIFSelect_ShareOutResult  This class gives results computed from a ShareOut : simulation before transfer, helps to list entities ... Transfer itself will later be performed, either by a TransferCopy to simply divide up a file, or a TransferDispatch which can be parametred with more details

CIFSelect_SignMultiple  Multiple Signature : ordered list of other Signatures It concatenates on a same line the result of its subitems separated by sets of 3 blanks It is possible to define tabulations between subitems Moreover, match rules are specific 
CIFSelect_SignType  This Signature returns the cdl Type of an entity, under two forms : 
CIFSelect_SignValidity  This Signature returns the Validity Status of an entity, as deducted from data in the model : it can be "OK" "Unknown" "Unloaded" "Syntactic Fail"(but loaded) "Syntactic Warning" "Semantic Fail" "Semantic Warning" 
CIFSelect_Transformer  A Transformer defines the way an InterfaceModel is transformed (without sending it to a file). In order to work, each type of Transformer defines it method Perform, it can be parametred as needed 
CIFSelect_TransformStandard  This class runs transformations made by Modifiers, as the ModelCopier does when it produces files (the same set of Modifiers can then be used, as to transform the starting Model, as at file sending time) 
CIFSelect_WorkLibrary  This class defines the (empty) frame which can be used to enrich a XSTEP set with new capabilities In particular, a specific WorkLibrary must give the way for Reading a File into a Model, and Writing a Model to a File Thus, it is possible to define several Work Libraries for each norm, but recommanded to define one general class for each one : this general class will define the Read and Write methods 
CIFSelect_WorkSession  This class can be used to simply manage a process such as splitting a file, extracting a set of Entities ... It allows to manage different types of Variables : Integer or Text Parameters, Selections, Dispatches, in addition to a ShareOut. To each of these variables, a unique Integer Identifier is attached. A Name can be attached too as desired

This includes that all its views are kept too, but empty; and annotations are not kept. Drawing Name is renewed 
CIGESSelect_RebuildGroups  Rebuilds Groups which were bypassed to produce new models. If a set of entities, all put into a same IGESModel, were part of a same Group in the starting Model, this Modifier rebuilds the original group, but only with the transferred entities.

CIGESSelect_SelectLevelNumber  This selection looks at Level Number of IGES Entities : it considers items attached, either to a single level with a given value, or to a level list which contains this value 
CIGESSelect_SelectName  Selects Entities which have a given name. Consider Property Name if present, else Short Label, but not the Subscript Number First version : keeps exact name Later : regular expression 
CIGESSelect_SelectPCurves  This Selection returns the pcurves which lie on a face In two modes : global (i.e. a CompositeCurve is not explored) or basic (all the basic curves are listed) 
CIGESSelect_SelectSingleViewFrom  This selection gets the Single Views attached to its input IGES entities. Single Views themselves or Drawings as passed as such (Drawings, for their Annotations)

CIGESSelect_SetGlobalParameter  Sets a Global (Header) Parameter to a new value, directly given Controls the form of the parameter (Integer, Real, String with such or such form), but not the consistence of the new value regarding the rest of the file 
CIGESSelect_SetLabel  Sets/Clears Short Label of Entities, those designated by the Selection. No Selection means all the file 
CIGESSelect_SetVersion5  Sets IGES Version (coded in global parameter 23) to be at least IGES 5.1 . If it is older, it is set to IGES 5.1, and LastChangeDate (new Global n0 25) is added (current time) Else, it does nothing (i.e. changes neither IGES Version nor LastChangeDate) 
CIGESSelect_SignColor  Gives Color attached to an entity Several forms are possible, according to <mode> 1 : number : "Dnn" for entity, "Snn" for standard, "(none)" for 0 2 : name : Of standard color, or of the color entity, or "(none)" (if the color entity has no name, its label is taken) 3 : RGB values, form R:nn,G:nn,B:nn 4 : RED value : an integer 5 : GREEN value : an integer 6 : BLUE value : an integer Other computable values can be added if needed : CMY values, Percentages for Hue, Lightness, Saturation 
CIGESSelect_SignLevelNumber  Gives D.E. Level Number under two possible forms : 
CIGESSelect_SignStatus  Gives D.E. Status under the form i,j,k,l (4 figures) i for BlankStatus j for SubordinateStatus k for UseFlag l for Hierarchy

CIGESSelect_UpdateCreationDate  Allows to Change the Creation Date indication in the Header (Global Section) of IGES File. It is taken from the operating system (time of application of the Modifier). The Selection of the Modifier is not used : it simply acts as a criterium to select IGES Files to touch up 
CIGESSelect_UpdateFileName  Sets the File Name in Header to be the actual name of the file If new file name is unknown, the former one is kept Remark : this works well only when it is Applied and send time If it is run immediately, new file name is unknown and nothing is done The Selection of the Modifier is not used : it simply acts as a criterium to select IGES Files to touch up 
CIGESSelect_UpdateLastChange  Allows to Change the Last Change Date indication in the Header (Global Section) of IGES File. It is taken from the operating system (time of application of the Modifier). The Selection of the Modifier is not used : it simply acts as a criterium to select IGES Files to touch up. Remark : IGES Models noted as version before IGES 5.1 are in addition changed to 5.1 
CIGESSelect_ViewSorter  Sorts IGES Entities on the views and drawings. In a first step, it splits a set of entities according the different views they are attached to. Then, packets according single views (+ drawing frames), or according drawings (which refer to the views) can be determined
