Hello,
from what I know there are 2 ways of doing depending on the laser cutter.
- Some laser cutting company asks for one drawing for each shape. For some of my project I doing that. I use a plugin to be able to output dxf. See there Low Table PatDef
- For some uses you’ll have to nest the curves. And for that the free and good choice is OpenNest
