1. Set Forward View Filled Visible Edges. The window appears with blue fill.
2. Generate DV drawing - Dynamic
3. Mstn generates DV and opens the Drawing model. Blue window fill is visible. Expected behaviour.
4. Go back to 3d model and generate DV as before but use CVE (Cached) setting
5. Mstn generates CVE and opens the Drawing model. Blue window fill is gone. :-(
