As Side Door sign<\/a> v3 seemed to have fallen off, I needed to make a new one. With access to a laser cutter, I can make really permanent things now, so I designed this:<\/p>\n

In order to get the sign to hang correctly, I needed to work out the centroid of the pointy outline. thedatachef\/inkscape-centroid: Centroids for Inkscape paths and shapes<\/a> to the rescue! Well, kinda. First off, the installer had a bug that said a Ruby file was a dependency when the plugin was in Python. So I forked the repo, made the change, tested it, and issued a pull request. So yay, working centroid calculations in Inkscape!<\/p>\n

Secondly, the plugin only works well for simple shapes, like these:<\/p>\n
