Hi Gregory Perasso
Thank you for your response
You are right in both of your assumptions: the assembly is a prototype for testing and by parts I mean CAD parts.
I am sorry for not being 100 % clear in my question.
I was aware that there is such a thing as a baseline, but I don't know how to make one... I guess that will be the project of the day...
Thank you for the help
Sincerly
