I'm looking to create an archimedes spiral feature in ProE 2.0. I've looked everywhere and can't seem to figure it out. The helical sweep only makes springs, so not sure how I can make it. Thanks in advance! Jay

I'm not sure what you mean by "the helical sweep only makes springs" - it makes whatever section you sketch, surely? If you're trying to model an auger (like a grain elevator, or archimedes water screw) then I'd probably start by revolving a solid "blank" and then using a helical sweep to cut away the slot (you'll need to leave a solid 'core' to stop it becoming a spring!). Really, this is just a male screw thread where the thread depth is nearly equal to the outside radius - and you can certainly use the helical sweep to model a screw thread.

Insert a DATUM CURVE feature by EQUATION, using the CARTESIAN type, and use a similar sets of equations as shown below. x=5*t*cos(10*t*360) y=5*t*sin(10*t*360) z=0 The 10 above controls number of complete turns, the 5 is straight line distance from the start of the curve to the end of the curve, or in this case 0.5 between successive turns. Once you have the desired curve you can sweep a section along it.
