If you use(d) inkscape to create models for laser cutting, chances are you have ran into the following problem: the laser cutter first cuts the large shape, then it ever so slightly moves, then the holes in that shape are created but with a small offset. Thats why I created this simple extension to deal with this! The extension exists out of a couple lines of code that will re-arrange the order of the vectors for you, so the small holes get cut first.
You might need to combine the desired contours using ctrl + K to build up a long "total path" object.
Draw some closed contours.
Make some "bad" order (first rectangle in the middle, then a small one, then a large outer one)
Combine and check
Combine the paths to common contour using ctrl + K. Check the 'd' node of the XML item to see how the path actually looks alike.
Run the extension
Check the 'd' node again
