I have a part where some 90° sketched bends originate from an obtuse corner (165°). In a swx drawing view, the flat pattern looks normal, but there appears to be some extra entities show up when I save as dwg (for a cnc cutter). So what appears to be a straight single line entity, is actually two colinear entities. The small extra entities seem to be within the bend radius. Is there any quick way within swx to eliminate the extra entities before making dwg files?

Thanks, Bill

Bill, it might be worth a try, save as a DXF first, than save that DXF to a DWG.

In the part file, under Flat-Pattern1, edit feature, make sure corner treatment is checked.
If you are using tear for auto relief, if the option appears, try the extend option. This option doesn't always appear in sketched bends.
If these don't work, I always check the dxf/dwg files for small lines manually - they play havoc with laser and punch programs. I have a utility that checks for short lines and arc called Cadcop. It's an autolisp program. We got it from NCell, but I haven't tried it yet. Theoretically it should run in DWGEditor.

Hi Bill,

Select the Flat-Pattern feature, edit feature and select merge faces. I would also set your templates with this option.

That should do it.
