Problem summary Modo can not Slice through a degenerate polygons.
Customer reported version modo.n/a
Customer reported platform windows10
Steps to reproduce
1) Open the attached scene file. It contains 2 mesh layers:
Good: 2 quads and 1 triangle. The triangle is not degenerate.
Bad: 2 quads and 1 triangle. The triangle is degenerate.
2) Activate the Slice tool.
3) Use the Slice tool to create and edge across the Good mesh. An edge will be created across each polygon, the triangle is sliced.
4) Use the Slice tool to create and edge across the Good mesh. The Slice tool will not create and edge on the degenerate triangle. To see this accurately:
5) Select the mesh layer Bad and switch to Vertex mode.
6) Go to Select > Use Selection Set. Use the selection set 'Vertex', which will select one of the degenerate vertices.
7) Move the vertex out and observe that the degenerate triangle has not be sliced.
It does not matter how many vertices the degenerate polygon has.

Earliest version tested 10.2v4 - This issue appears to be in all versions of the product
Expected behaviour Slice tool should slice degenerate geometry.
Actual behaviour Slice tool can not slice degenerate geometry; no edge is created.
