I have some hexagonal holes whose distance between opposing sides is specified (hex nuts). It would be nice to be able to create the hexagon using the inscribed radius (distance between opposite sides) instead of the proscribed radius (distance between opposite vertices) so I don’t have to calculate the proscribed radius. Please add an inscribed/proscribed radius option to the polygon tool.
