PCB Edge Cut Calculations

Six "sided" LED Randomizer a.k.a. an electric die

I originally intended on using Inkscape to design and export a DXF file to specify the edge cuts on the PCB in KiCAD. However, I had a bit of difficulty understanding how to use Inkscape for precise layout. Instead, because my design was a rather simple geometry made up from a series of triangles, I could calculate the coordinates for each point and use KiCAD's coordinate system directly. The strange thing in PCBNew is that the origin is a random point in the upper left, outside of the border of the design space, but I just used that origin (instead of calculating offsets) and then moved the final polygon into the layout space.
