Hi, I have opened a dxf file in CAM only for the file not to open correctly. Can you advise why this is? screenshot attached of simple dxf (correct) and they same file shown in CAM with changes.
See docs:software:file-errors [OpenBuilds Documentation] - your overlay hides the document tree, but I would bet you can see a lot of non-polyline entities in the document tree in the top right. Convert everything to Polylines.
