This applies not only to geometry but also inertia, color, force constants, joint state targets, etc. In other words, you can use this approach for almost any situation where two different blocks rely on a common parameter.

I created a body and I parameterized it through the creation of a subsystem and a mask. Now I have to create the second body, but I don't know to make the length of the first body as global so the second body can see it.

Hi Tony,

thanks for your reply. It works but:
1- the dimension of each element of a body is connected to the parameters with some formulas, many of them are not straightforward ones. To reuse all bodies in other models, I need to inizialize the body length in the subsystem and not in the model workspace. How could I do that?
2- I start the simulation in a objective function. How can I change the paramater though it?


Best regards
