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? ![IMG_20231211_182509137](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/0/0cee1a729dd9ee6df9d677764d9a786eb79e3a52.jpeg) ![IMG_20231211_182434443](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/0/02ba034ea457a5f6a6e70814c79c76b657245b51.jpeg) ![IMG_20231211_182421000](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/3/3c76c49a21e95f098d5abad1e1c0c692e5171e7e.jpeg) The DXF file [mathew.dxf](https://forum.arcdroidcnc.com/uploads/short-url/ak0GASGAgP6XE5VinOziMD4sF4a.dxf) (259.3 KB) ---

@Matt_UK 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. Cheers AM
