I have attached an example of the need for the ability to nest parts within parts.  Large window area 61.5x25.5 that is cut out.  There are a lot of parts on this project that would fit and to make matters worse there are a lot of these on this project.  Yes that portion can be taken to a beam saw and used by manually entering the size and placing parts on it but why?  Why can we not get this in Microvellum?
