# Offset Paths

Create offset for open or closed paths. Python library **pyclipper** needs to be installed. Use [Approximate Curves by Straight Lines (Flatten Beziers)](https://wiki.stadtfabrikanten.org/books/in-house-extensions/page/approximate-curves-by-straight-lines-flatten-beziers "Approximate Curves by Straight Lines (Flatten Beziers)") extension in advance of this plugin.

## Draw some [Ratchet](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz-shape-generators/page/ratchet) (as example)
