right.. drawing all the pieces to subtract can be the part that takes the longest.
one thing to note, if you do end up going that route, is that you can have multiple solids inside a group and it will still count as a single solid. (so the Boolean action can happen once instead of doing each 'C' (in this case) individually.).. it can't be soild groups inside a group though.. all raw geometry inside one single group.
in other words.. draw two unconnected cubes.. group them together.. these cubes will be recognized as a solid group and can be used with the solid tools.
good luck.
True, ultimately it may just easier to automate the cutting object process through ruby. Something like "Lines to cube tube" Something like Didier's "Lines to Tubes" except that it will create 4 sided solid cutting object or shelled multiple objects. Unfortunately free users would not benefit from this. I wish Profile Builder worked on multiple paths at the same time.
