Part: Attacher intersection calculation fix
Part: Attacher intersection calculation fix

===========================================

In OCCT 7.4 (and apparently <= 7.4 too):

A GeomAdaptor_Curve obtained directly from BRepAdaptor_Curve will not work because it won't respect the
Location/orientation of the underlying curve.

This commit proposes to create a new GeomAdaptor_Curve from an intermediary curve handle to work around
this issue.
