BooleanUnion is serious math… Hats off to Rhino team - it gets better every release.
Have got a closed solid polysurface and need to booleanunion extruded letters into the poly… Have got most of the letters to union by using the trick of first using split and then doing the union… However, a few letters just wont do the split,then,union (even when I move their positions slightly to goose the split math).
See attached file. Need a trick of two, if you guys can think of something…
