To use FreeCAD with a Lasercutter, design your project with the “part design” workshop, assemble it with the “assembly2” workshop and then fire the “LCInterlocking” workshop on your assembly.

Now you need to export it to a SVG file, except that if you use the “export to flattened SVG” function on the Shape2DViews generated by the LCI workshop, the circles are going to be exported with a really low poly count.

To solve this issue, create a new page in the Draft workshop, add views of each of your parts generated by LCI (named testXXX), to the draft and then use the Draft workshop function to export to SVG.
