Aug 14, 2013 · A few days ago a Quantum GIS user sent me a polygon shapefile that was giving her a big headache. When she needed to digitize new polygons using the "avoid intersection" feature (that allows to draw perfectly adjacent polygons, without worrying too much with the snapping), the new geometry didn't stick in the canvas. Reuleaux's original motivation for studying the Reuleaux triangle was as a counterexample, showing that three single-point contacts may not be enough to fix a planar object into a single position. The existence of Reuleaux polygons shows that diameter measurements alone cannot verify that an object has a circular cross-section.
