DXF file weird interpretation

When editing some DXF files in Trace I get this weird curve. It only appears if the kerf value is above zero. The lines are all “poly lines” from QCAD. Any ideas?

Yup this is a tough one with .dxf for the ArcDroid… DXF is a 40 year old format so it comes with a lot of baggage. And sometimes that baggage breaks the Kerf Algorithm.

Make sure you are running the latest version of Simple Trace as we’ve added a lot of little fixes into the software so far that take care of some of this broken kerf baggage.

I’ve forwarded the file to my code as perhaps you’ve found a new bag for us to work around.
