Extrema_ExtCC and coincident curves
Mauro Mariotti 2013/01/29 13:28
Hello,

with two coincident curves, Extrema_ExtCC (called by either GeomAPI_ExtremaCurveCurve or BRepExtrema_DistShapeShape) is extremely slow.

Is this a bug, or should I check it before calling it?
In the latter case, is there any method to check if two curves are partially or completely overlapping?

Thanks.
Mauro

hey mauro,

i'm not sure if i understood. but when you want to check with two curves are partially or completely identical you can use something like that in the following link:
