This function builds (in the parametric space of the plane P) a 2D curve equivalent to the 3D curve C. The 3D curve C is considered to be located in the plane P. Warning The 3D curve C must be of one of the following types: More...  
static Handle< Geom_Curve >  To3d (const Handle< Geom2d_Curve > &C, const gp_Pln &P) 
Builds a 3D curve equivalent to the 2D curve C described in the parametric space defined by the local coordinate system of plane P. The resulting 3D curve is of the same nature as that of the curve C. More...  
The GeomAPI package provides an Application Programming Interface for the Geometry.
The API is a set of classes and methods aiming to provide :
The API provides classes to call the algorithmes of the Geometry
For example to evaluate the distance <D> between a point
and a curve , one can writes :
D = GeomAPI_ProjectPointOnCurve(P,C);
or
GeomAPI_ProjectPointOnCurve PonC(P,C); D = PonC.LowerDistance();
