Hello. I want to run a DMU kinematics on a main product which is comprised only by sub assemblies of n copies of sub product "a". The first product "a" was inserted as existing component, while the other copies where instantiate. The sub assemblies are flexible, and I added the needed tot joints between them. Nevertheless, the "assembly constraint conversion" recognizes only 1 rigid joint, giving a rigid mechanism. What I do wrong?? Thank you!
