Helix constrain?

Is there a way to constrain 2 parts as a screw and nut? and How?

TIA

Hi,

If you mean that you want one part to follow the other as though on a
thread then you could maybe use a CAM mate. If you create a surface
using a sweep and the twist along path option you should get something
that looks like a helical screw surface. Then you could try mating to
an edge of that.

I dont have SW here to play with, it's just an idea - hope it helps.

Cam won't mate to the edge or surface of an helical cut. Tangent works, but
overconstrains the coaxial nut/screw.
Thaught there was a kind of "gear" constrain to have it work.

Thanks

Ended to mate the helical cut to a point on the "nut". Works, but not quite
what I was looking for.

 

JM,

Scott Baugh has an example of a helix mate on his site at

Look at the first file from Denny Trimble.
