Hi all

Can anyone tell me how to create the adjustable screw in Pro-E? Does anyone know how to do this now.

I look forward to hearing form you.

I suggest making a helical sweep surface along the length of the screw for the center of the "thread".  Then make a variable section sweep using a curve along the axis of the screw as the primary trajectory and then the edge of the surface as the other trajectory.  Then the section can be the "thread"  the length of the thread can be controled with a relation such as "sd0 = 185-(185-27.5)*trajpar.  where sd0 is the length of the thread, 185 is the radius at the large end and 27.5 is the radius at the small end.

Good luck,
