The Curve from BRepAdaptor allows to use an Edge
of the BRep topology like a 3D curve.
It has the methods the class Curve from Adaptor3d.
It is created or Initialized with an Edge. It
takes into account local coordinate systems. If
the Edge has a 3D curve it is use with priority.
If the edge has no 3D curve one of the curves on
surface is used. It is possible to enforce using a
curve on surface by creating or initialising with
an Edge and a Face.

Public Member Functions | |
DEFINE_STANDARD_ALLOC | BRepAdaptor_Curve () |
Creates an undefined Curve with no Edge loaded. | |
BRepAdaptor_Curve (const TopoDS_Edge &E) | |
Creates a Curve to acces to the geometry of edge <E>. | |
BRepAdaptor_Curve (const TopoDS_Edge &E, const TopoDS_Face &F) | |
Creates a Curve to acces to the geometry of edge <E>. The geometry will be computed using the parametric curve of <E> on the face <F>. An Error is raised if the edge does not have a pcurve on the face. | |
void | Initialize (const TopoDS_Edge &E) |
Sets the Curve <me> to acces to the geometry of edge <E>. | |
void | Initialize (const TopoDS_Edge &E, const TopoDS_Face &F) |
Sets the Curve <me> to acces to the geometry of edge <E>. The geometry will be computed using the parametric curve of <E> on the face <F>. An Error is raised if the edge does not have a pcurve on the face. | |
