Having a display similar to Dynamo or the 3ds Max material editor showing the masses, reference planes, dimensions, and paramaters and how they are linked would make trouble-shooting complex families (like there is any other kind?) especially those families made by other people or companies, far easier. I've had to manually do this with workflow diagram programs like Praxis thus far and it is time-consuming and error prone. If I have a family from someone else hat doesn't work quite right, it's often faster and easier for me to recreate the family from scratch than to try and diagnose and resolve the problem. Having this visual mode to see the connections would make diagnosing the issue much easier and save me tons of time.
