Summary0000794: Offset produces invalid shape
DescriptionThe offset algorithm produced invalid result when offseting an attached face:

Draw[]> restore tooffset.brep a
Draw[]> offsetshape r a 10
Draw[]> checkshape r

The case comes from E-learning, so there is no urgency.

For information, original face is obtained from IGES (file to be attached) and
then converted from C0 to C1 by 'bsplres a <fromiges> 0.001'. The effect seen in
3d viewer: no shading on offseted shape
TagsNo tags attached.
