Skeleton
To find a medial axis or straight skeleton. Skeleton is a thin version of that shape in the middle like the roof ridge line, that is equidistant to its boundaries. There is also an option to create an Inner Contour from the boundaries, instead.
This tool is based on a solution contributed by Marco Vitale in the Facebook group Inside the Node. I have added some extra features, such as the ability to choose between “Medial Axis” and “Inner Contour”.
We have several refinements and aids: the ability to soften the effect in sharp corners, an option to see the curvature map used in the process, another option to overlay the initial shape on the result, and other controls for thickness and contraction degree applied.
