I have an assembly model with some threaded parts. How can the parts be mated so that the threads appear to be properly engaged when viewed in cross-section?
I have no good idea but previously my method is using angle mate to define the relative rotation angle of the screw and the hole and adjust the angle mate manually until no overlapping.
If you create your own thread always start the helix at the same spot, 0, 90, 180, 270 degrees that way when you mate them you'll be right on..
I have a dimensions named ThreadStart@xxxxx in both the internal thread and external thread sketches. This dimension allows the center of the thread to float either direction parallel to the thread axis. In one part make this dimension value P x 1, P x 2, P x 3, etc. In the other part make this dimension P x .5, P x 1.5, P x 2.5, etc. Then create an axial mate that corresponds to origin of the ThreadStart dimensions and a mate where both sketches are coincident.
