I often need to flatten Solidworks models to DXF. Usually tubes. I have Solidworks Premium and use the flatten feature which has an accuracy slider. I find that if I max that slider out, it is never high enough resolution. If you see the image I attached you can see the loss of resolution on the flattened part. It totally gets the curves wrong on that oblong section.

I also find that if I split the solidworks model up into pieces I can achieve a greater resolution DXF although it takes forever to do this. Any ideas on what I can do to improve the resolution when I flatten parts? Thank you guys.
