I'm learning how to use TurboCAD. I have two solids (call them A and B). I would like to align one surface of solid A such that it is parallel to one surface of solid B. I can't find a way to make this happen. Is there a simple way? Alternately, is there a simple way to align a selected surface of a solid  parallel with a given workplane? If so, this would address my problem.

Note that I do not want to change the shape of the solids. So the tool that make one face align with another face is not what I need. I just want one solid to be rotated to make two faces parallel.

Thanks.

Howdy R!   prolly the best route would be to do a rotate of the (moveable) part via the rotate/ or mirror tools. ( workpin normal would be the 90 degree view= top side etc) with the Option button being the copying "switch" button to turn on.

Try using the Align tool.

Are you referring to one of the global work planes or a custom one? Either the gripper or rotate tool will work.
