Hi @drafting_nufab. I am glad I was able to help you some. I do not use the Frame Generator or Content Center stuff that much anymore, and even when I was, I was not controlling them by code. I know that the files they generate are generally ReadOnly, like Library files, are given 'generated' names, and stored in a specific location/file structure. Some of these aspects did not work very well with how we need to be able to do things, or with our filing system/structure. What few things we did use from those resources, we sometimes copied a file externally, then converted it into a 'regular' part, then controlled its size/shape by other configuration means, such as by using iLogic. So, I am not personally sure how you would 'map' one detail to another within that Content Center system by code.
As for learning to control Inventor by utilizing its API and iLogic, that is something that most folks just seem to learn as they go, by trial & error testing, looking at existing examples and breaking it down logically, and reviewing every little iLogic related resource we see available along the way. There does not seem to be a super good one stop place to learn everything there is to learn about the Inventor API, or the iLogic API. However, I have attached a PDF that you might find helpful. Good luck. It has been a very rewarding journey for me, so I hope it will be for you also.
