# Bezier Envelope

This extension is similar to default Inkscape extension "Modify Path → Envelope" and is also similar to [Another Perspective](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/page/another-perspective).

Note: this extension does not work for svg:circle which were converted to svg:path. Those will contain a or A commands in their path. We need to convert those to paths with c or C commands!

## Draw the path you want to fit into the envelope

## Draw your 4-sided envelope around

**Please note!**

- Paths with more than 4 sides will not correctly apply. Paths with less than 4 sides will fail. So just draw a square shape (angles don't have to be 90 degrees)
- Start in the upper left corner and draw clockwise. Otherwise your result may get twisted in an undesired way

## Run the extension

First select the inner path. As second select the envelope. If you dismiss the order the extension will fail.
