# Optimize Sequence: Small Holes First Souce of Documentation: [https://github.com/L0laapk3/inkscape-laser-sequence-extension](https://github.com/L0laapk3/inkscape-laser-sequence-extension) 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.

Also have a look at [Line Sorting](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/page/line-sorting) and [Optimize Sequence: Travel Distances](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/page/optimize-sequence-travel-distances)

## Example ### Draw some closed contours. Make some "bad" order (first rectangle in the middle, then a small one, then a large outer one) [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/ngjRRoJcF5v7Qk3v-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/ngjRRoJcF5v7Qk3v-grafik.png) ### 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.
