oCAdaptor3d_SurfaceOfRevolutionThis 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. Curve and Axis are coplanar.

oCAISApplication 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:
oCAIS_AngleDimensionAngle dimension. Can be constructed:
oCAIS_AttributeFilterSelects Interactive Objects, which have the desired width or color. The filter questions each Interactive Object in local context to determine whether it has an non-null 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
oCAIS_AxisLocates 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
oCAIS_BadEdgeFilterA Class

oCAIS_Chamf2dDimensionA framework to define display of 2D chamfers. A chamfer is displayed with arrows and text. The text gives the length of the chamfer if it is a symmetrical chamfer, or the angle if it is not
oCAIS_Chamf3dDimensionA framework to define display of 3D chamfers. A chamfer is displayed with arrows and text. The text gives the length of the chamfer if it is a symmetrical chamfer, or the angle if it is not
oCAIS_CircleConstructs circle datums to be used in construction of composite shapes
oCAIS_ColoredDrawerCustomizable properties
oCAIS_ColoredShapePresentation of the shape with customizable sub-shapes properties
oCAIS_ConcentricRelationA 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
oCAIS_ConnectedInteractiveCreates 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

oCAIS_DiameterDimensionDiameter dimension. Can be constructued:
oCAIS_DimensionAIS_Dimension is a base class for 2D presentations of linear (length, diameter, radius) and angular dimensions
oCAIS_DimensionOwnerThe 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
oCAIS_EllipseRadiusDimensionComputes geometry ( basis curve and plane of dimension) for input shape aShape from TopoDS Root class for MinRadiusDimension and MaxRadiusDimension
oCAIS_EqualDistanceRelationA 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
oCAIS_EqualRadiusRelation
oCAIS_ExclusionFilterA 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
oCAIS_FixRelationConstructs 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
oCAIS_GlobalStatusStores information about objects in graphic context:
oCAIS_GraphicTool
oCAIS_IdenticRelationConstructs a constraint by a relation of identity between two or more datums figuring in shape Interactive Objects
oCAIS_IndexedDataMapNodeOfIndexedDataMapOfOwnerPrs
oCAIS_IndexedDataMapOfOwnerPrs
oCAIS_InteractiveContextThe 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:
oCAIS_InteractiveObjectDefines 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
oCAIS_LengthDimensionLength dimension. Can be constructued:
oCAIS_LineConstructs line datums to be used in construction of composite shapes
oCAIS_ListIteratorOfListOfInteractive
oCAIS_ListNodeOfListOfInteractive

oCAIS_MidPointRelationPresentation of equal distance to point myMidPoint
oCAIS_MinRadiusDimension– Ellipse Min radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset))
oCAIS_MultipleConnectedInteractiveDefines an Interactive Object by gathering together several object presentations. This is done through a list of interactive objects. These can also be Connected objects. That way memory-costly calculations of presentation are avoided
oCAIS_OffsetDimensionA framework to display dimensions of offsets. The relation between the offset and the basis shape is indicated. This relation is displayed with arrows and text. The text gives the dsitance between the offset and the basis shape
oCAIS_ParallelRelationA framework to display constraints of parallelism between two or more Interactive Objects. These entities can be faces or edges
oCAIS_PerpendicularRelationA framework to display constraints of perpendicularity between two or more interactive datums. These datums can be edges or faces
oCAIS_PlaneConstructs plane datums to be used in construction of composite shapes
oCAIS_PlaneTrihedronTo 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:
oCAIS_PointConstructs point datums to be used in construction of composite shapes. The datum is displayed as the plus marker +
oCAIS_PointCloudInteractive object for set of points. The presentation supports two display modes:
oCAIS_RadiusDimensionRadius dimension. Can be constructued:
oCAIS_RelationOne 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:
oCAIS_Selection
oCAIS_SequenceNodeOfSequenceOfDimension
oCAIS_SequenceNodeOfSequenceOfInteractive
oCAIS_SequenceOfDimension
oCAIS_SequenceOfInteractive
oCAIS_ShapeA 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 non-HLR - 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
oCAIS_SignatureFilterSelects 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 non-null 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:
oCAIS_StdMapNodeOfMapOfInteractive
oCAIS_SymmetricRelationA 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
oCAIS_TangentRelationA framework to display tangency constraints between two or more Interactive Objects of the datum type. The datums are normally faces or edges
oCAIS_TextLabelPresentation of the text
oCAIS_TexturedShapeThis 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
oCAIS_TriangulationInteractive object that draws data from Poly_Triangulation, optionally with colors associated with each triangulation vertex. For maximum efficiency colors are represented as 32-bit integers instead of classic Quantity_Color values. Interactive selection of triangles and vertices is not yet implemented
oCAIS_TrihedronCreate a selectable trihedron there are 4 modes of selection : mode = 0 to select triedron ,priority = 1 mode = 1 to select its origine ,priority = 5 mode = 2 to select its axis ,priority = 3 mode = 3 to select its planes ,priority = 2 a trihedron has 1 origine,3 axes,3 planes. Warning For the presentation of trihedra, the default unit of length is the millimetre, and the default value for the representation of the axes is 100. If you 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 Prs3d_Drawer_FirstAxisAspect. You 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
oCAIS_TypeFilterSelects Interactive Objects through their types. The filter questions each Interactive Object in local context to determine whether it has an non-null 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

oCBRepFeatBRepFeat 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:
oCBRepFeat_BuilderProvides 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
oCBRepFeat_FormProvides general functions to build form features. Form features can be depressions or protrusions and include the following types:
oCBRepFeat_GluerOne 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
oCBRepFeat_MakeCylindricalHoleProvides a tool to make cylindrical holes on a shape
oCBRepFeat_MakeDPrismDescribes 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:
oCBRepFeat_MakeLinearFormBuilds 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:
oCBRepFeat_MakePipeConstructs compound shapes with pipe features. These can be depressions or protrusions. The semantics of pipe feature creation is based on the construction of shapes:
oCBRepFeat_MakePrismDescribes functions to build prism features. These can be depressions or protrusions. The semantics of prism feature creation is based on the construction of shapes:
oCBRepFeat_MakeRevolDescribes functions to build revolved shells from basis shapes
oCBRepFeat_MakeRevolutionFormMakeRevolutionForm 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:
oCBRepFeat_RibSlotProvides 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:
oCBRepFeat_SplitShapeOne 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

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).

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.

For a B-spline surface the discontinuities are localised at the knot values. Between two knots values the B-spline 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 B-spline functions and Mult the multiplicity of the knot of range Index in the given direction. If for your computation you need to have B-spline surface with a minima of continuity it can be interesting to know between which knot values, a B-spline patch, has a continuity of given order.

oCGProp_PEquationA framework to analyze a collection - or cloud
oCGProp_PGPropsA framework for computing the global properties of a set of points. A point mass is attached to each point. The global mass of the system is the sum of each individual mass. 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. Nonetheless, you are advised to restrict your use of a GProp_PGProps object to a set of points and to create a GProp_GProps object in order to bring together global properties of different systems

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

oCHLRAlgoIn 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
