Flat Pattern DXF exporting incorrectly

[frankVBVB4]

I created a screen cut out panel using a tool in Fusion. This cut out a fairly complicated pattern which I then exported as a flat pattern. See attached files.

I opened your DXF in Autodesk DWG Trueview and the file looks fine to me. What specifically is your problem and don't leave any details out. 

Nevermind, I see now where some lines are missing and in the wrong place.

Hi,

This way (almost) always succeeds.

I reported this problem in another post last week. There is a bug where elliptical arcs are flipped. If you create a sketch and project the face and bend lines into the new sketch, Save As DXF will give the correct output, see attached f3d.

Here in Rhino you can see the bad flat pattern and above what you get using Save As DXF.
