Honeycomb

The honeycomb motif as in FVS-222 is an advanced design that step by step creates (helper) points by interpolating and the use of the fred function. It is a "Projected crossover" used in a way to get a perfect honeycomb pattern. Note that the actual cuttings angles are computed and adapt when the starting position changes due to e.g. optimization. GemCad allows designing (by using Shift-click) checkerboards but not more "free form" patterns like this one.
