Is2DClosed() added to reject an improper existing surface Add OnlyClosed=Standard_False argument Call BRepLib_FindSurface with OnlyClosed=Standard_True fix Is2DClosed() to check intermediate points of wire in 2D fix Is2DClosed() - correct tolerance used for the last point fix Is2DClosed() - correct getting 2d points to compare

class FindSurface from BRepLib
|
|
|
|
---Purpose: Provides an algorithm to find a Surface through a
|
|
-- set of edges.
|
|
--
|
|
-- The edges of the shape given as argument are
|
|
-- explored if they are not coplanar at the required
|
|
-- tolerance the method Found returns false.
|
|
--
|
|
-- If a null tolerance is given the max of the edges
|
|
-- tolerances is used.
|
|
--
|
|
-- The method Tolerance returns the true distance of
|
|
-- the edges to the Surface.
|
|
--
|
|
-- The method Surface returns the Surface if found.
|
|
--
|
|
-- The method Existed returns returns True if the
|
|
-- Surface was already attached to some of the edges.
|
|
--
|
|
-- When Existed returns True the Surface may have a
|
|
-- location given by the Location method.
