Polygen
Inkscape extension that creates a paper model from a silhouette.
Given an open path (silhouette) and a centerline, this program generates (1) one side of an 'n' sided polygonal paper model; top and bottom lids for the assembled model; and (3) a wrapper for the one-sided model.
Update: Now allows you to specify the color of solid score lines
Installing:
Copy polygen.inx and polygen.py into your Inkscape user extensions directory. Where is that? Open Inkscape and go to the System section of the Preferences menu (Edit --> Preferences --> System). You will find a User extensions item containing the path to your user extensions directory.
Usage:
See the file How_to_Use_Polygen.pdf for details.
Note:
This extension (for Inkscape version 1.1.) is functional, but not bulletproof, so be mindful of the input constraints in the usage document.
