This Inkscape extension lets you delete lines shorter than a given threshold.
The extension was made to clean up heavy PDFs exported from SketchUp, but can probably be used in various other situations too.
Copy the content in src/ into your Inkscape extension directory. The extension directory path can be found in Edit > Preferences > System inside of Inkscape.
- Fork and clone the repo to your computer (to other location than Inkscape extension directory).
- Set up symlinks in the Inkscape extension directory pointing to the extension files.
Developing directly in the Inkscape extension directory is not recommended. When doing so different extensions projects can't be in different repositories, as Inkscape loads all extensions from the same directory. Instead develop in a separate directory and use symlinks pointing to the repository files from the extension directory. On Windows the Link Shell Extension can be used.
