Sheet Metal Question

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.

 

1. In the part file, under Flat-Pattern1, edit feature, make sure
corner treatment is checked.
2. 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.
3. 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.
