BRepBuilderAPI_Copy and meshes

Istvan Csanady's picture

I have noticed that BRepBuilderAPI_Copy does not even try to copy the meshes of edges. This causes BRepMesh_IncrementalMesh to recalculate the mesh of the entire copied shape, even if the underlying meshes existed in the original shape.

So currently the copyMesh flag is misleading. Is this a bug, or an intended behavior of OCCT?

This is a bug

Dear Istvan,

The problem you described is really a bug. It is forgotten to copy meshes from edges while implementing copying procedure.

I have registered issue #26897 in Mantis.

Thanks for the report,
Artem
