You can use a gear connection in Pro/ENGINEER Wildfire 5.0 to convert a rotation into a linear move

I model all of my threads with a helical swept cut using the actual thread dims for major/minor rott width etc.. If you do this you can create a curve at the pitch diameter on the male and female thread (ill assume you can figure this out). Then I create a point on one of the curves. Create a slot connection with the point and the curve. Works like a charm.

Clever solution, Paul! Also note that, outside of the Mechanism and Connection realm (using regular assembly constraints), you can write a Relation that controls a rotational constraint value based on a mate offset value to give you realistic positioning.
