class Curve from BRepAdaptor inherits Curve from Adaptor3d
|
|
|
|
---Purpose: 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.
