Frame generator would be a much more powerful tool if it were not limited to one-of situations. What I would like to see is the ability to place iLogic driven assemblies that use frame generator so that configurators can use frame generators powerful functionality. An example would be a configurator for cabinets that use Frame Generator for the face frame.
You can do this with iLogic Design Copy, but that is a work-around, not a solution. Having Frame Gen designs available in Place iLogic Component would allow those who create configurable elements for much larger designs to be far more productive.
