Cubify Invent is remarkably bug free. But, it does have some behaviors that might have to be addressed in future versions.
Using EXTEND, MOVE, ROTATE we explore some behaviors that are a bit puzzling or surprising. We make an attempt to determine if these behaviors constitute a purposeful feature or a potential bug.
So far, there are no "Show Stoppers" that we've identified. In fact, almost all of the questionable behaviors that we have seen have relatively minor impact on our ability to design.
