Thank you for your suggested workaround to this missing Carbide Create feature. I can see where this method would work for poly objects that can be easily scaled up to a second boundary object, one cutter width size larger all around than the original, and broken into pieces so a pocket toolpath can be created rather than an outside/right path to leave "tabs" and remove most of the material around the object to be cut completely free. However, having tried it for real when making components for a wooden clock project its still a significant design effort, if I understand your methodology correctly, and much more time consuming if the poly object has indentations, for lack of a better word, since the original boundary of the object cannot be simply scaled up.
Many of my parts have this problem and for this reason I'm looking at spending $ for a program capable of auto-creating the tabs and easily re-positioning them (Trialing VCarve). If I knew Carbide Create had this feature scheduled to be released I would hold off. It's too big a deal for me to wait indefinitely on though. I can't walk more than a few arms length away from the jobs right now without worrying about how close the part is to being freed and the part being destroyed or damaged. I've tried the Winston Moy suggested double sided tape, and I've tried leaving a few thousands of an inch and cutting around the object and sanding. Both of these methods are more problematic than tabs; 1) the tape doesn't always do it's job and leaves residue and 2) accurately leaving a few thousands of an inch is guesswork in reality on stock produced from a thickness planer - the planer does not cut the entire stock this accurately.
Carbide Create probably needs this feature added more than any other imo.
