DeleteFace1 -> Compute Failed

[xplsek01]

Insert mesh from STL file.
Generate Face Groups (Accurate).
Convert Mesh (Parametric, Faced).
Select a facet and try to delete one.
The error message appears: DeleteFace1 -> Compute Failed.

Expected behavior:
1. The facet is deleted and a gap is self-treated.

2. More meaningful error message about what is really going on is printed out.

If this were my work I would use the stl mesh only as reference in creating proper native geometry.
