Hi all,

I'm creating a mechanism with simmechanics second generation libraries, that it is composed of several compounds body and the dimesion of each body is related to the length of one body (i.e. body_length). 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. 
Hopefully to have explained correctly my question, if not, don't hesitate to ask me something. 

Best regards

Michele
