hello, when i assemble these parts, i cant move the part that should open and close. the hinge doesnt rotate. I need to solve it asap. hope someone can help me out.
There seems to be some models missing from your uploads and the assemblies don't build properly so I'm going to take a guess that you need to select the subassembly with the hinge that is supposed to move and edit it's 'component properties' to 'solve as flexible'
