Summary0023190: offset Draw command raise exception "Offset with no C1 Surface"
DescriptionIf input shape have faces with C0 continuity then offset command raise exception "Offset with no C1 Surface".

It is possible to split C0 faces to several C1 faces in order to avoid such limitation. It is proposed to include such processing to offset algorithm.
Steps To Reproducesee tests:
offset shape A2 A3

C0 faces:
A2: s_6, s_10
A3: s_74, s_79
TagsNo tags attached.
Test case numberNot needed

I think it would be worth to have an algorithm that made splitting of C0 faces to C1 faces. Such algorithm could be used not only in offset, but in some other places. In offset, we could add an option that forces a call to the splitting algorithm. In this case, we should also carefully maintain the modification history.

This algorithm is available, see ShapeUpgrade_ShapeDivideContinuity

So, in the scope of this issue we will add the option of splitting the faces on C1 continuity in the offset algorithm.
