Extruder for 3-d Papercraft
Sue Zakar
This extension creates the pieces needed to construct a 3D extruded papercraft project from a path (composed of straight segments) that defines its shape. Tabs and score lines are included. Both the decorative an the structural pieces are created. When installed, it will be under Extensions -- Papercraft Most recent documentation and code are at the link provided Updated to correct scoring color: 08/19/2022

Tabgen 3D Papercraft Extension
Sue Zakar
Tabgen Papercraft Extension for Inkscape 1.1 by Obzerving Use the tabgen extension to add tabs on pieces for assembling papercraft projects. Please read the important setup info below. After installing, it is available under Extensions->Papercraft->Tabgen Using it is very simple and straightforward. Select the path that you want to put tabs on. Run the extension. It will generate a new piece with tabs along the outside edge, and/or any enclosed path (i.e. along the inside of cutouts.) The tabs have scorelines. The path MUST contain only straight segments, as tabs cannot be generated on curves. Every segment will create a tab, so eliminate stray nodes. New version allows for selective tab placement. Options/Parameters The angle of the tab is the angle used at the edges of the tab. The height of the tab is how far away from the path the tab extends. The length of the dashline is how large any one cuts making up the score line is. Making this number too large may result in missing score marks. If zero is used, the score line will be solid, and will not be part of the path, but will be a separate path grouped with it. The choice for tab placement are outside, inside and both. This affects whether tabs are placed along the outer path, inner paths (holes), or both. Dimension units are the units in which you specify your setting for height and length. Keep this consistent with your document parameters.

Polygen - 3D Papercraft Extension
Sue Zakar
Polygen is used to create the pieces needed for 3D papercraft objects like vases. It takes a path (composed of straight segments) that describes the shape of the objects profile, and a centerline. Then, with the number of sides as a parameter, it constructs the shape of the pieces needed to form that shape in 3D, including tabs and scorelines, and untabbed pieces for use in decorating the outside. Latest version will be at the external link.

Horizontal Lines Effect (hlines)
Sue Zakar
Inkscape extension for "unwinding" paths For each selected path element consisting of straight segments, this extension creates an additional path element consisting of horizontal line segments which are the same size as the original line segments. Installing: Copy hlines.inx and hlines.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. NOTE: As of this time, this extension works under Inkscape 1.0, but not the 1.1 release candidate. However, it will work on 1.1 (and above) by commenting out line 45 of hlines.py and uncommenting line 46. Update: 06/24/2021 new version handles transforms better
