Hi Im trying to figure out if its possible to move hinged assemblies on- screen by selecting & dragging the moving part of the assembly. I currently assemble the hinge with the standard commands, ie, Insert both axis together, Align the central planes & finally Mate Angle to define the open/closed position of the hinge. Then if I want to open/ close the assembly - I go into & redefine the above angle & then regenerate. Im sure there is a more slick way to do this - searched everywhere for instructions but cannot find it anywhere. Ive played around with the Pin Constraint but could not get it working. Is this possible?? I do not have the Mechanism Application add-on. Im running WF4.0. Id appreciate any advice on this Thanks i advance Mark
