Hey everyone,So I have a question regarding parameters in a block definition, or more specifically how to constrain parameters. I have attached a PDF showing exactly what I am working on. Basically I have an arm for a monitor which I need to add some parameters to. I need to be able to have a point that I can grab where the "primary grab" is located, and when I grab that I need the arm to pivot at the indicated pivot point, but be restrained by the first arm that is constrained to the circle. Is this possible to do in AutoCAD?Hopefully that makes sense, and really hope that someone can help me out here!uploads/66884/Parameter_Example.pdf
