Pattern
Pattern
(OP)
I need some help with a pattern in a part file. I'm using SW2004 SP3. I have a cut sweep modeled on the end of a round part. I now need to pattern that cut sweep around the center of the part every 5 degrees, at the same time each rotation has to incrementally move in the Z axis (along the centerline of the part) 0.005. How can I accomplish this, I have been trying sketch driven pattern using a 3d sketch but cant get it to rotate about the center of the part even with the origin picked as the reference point. My 3d sketch is points that are placed on a helix with Height and revolution.

RE: Pattern
Perhaps you could create your sweep feature as a separate body, then pattern the body and adjust the rotation of each instance individually.
RE: Pattern
I need each step to also move the 0.005 down while also rotating the 5 degrees so I don't think the Circular pattern will work.

RE: Pattern
I found my problem with the sketch driven pattern, it takes the origin of the sweep, which is center of the part and moves it out to the points in the sketch that I'm trying to use to drive the pattern. My driving sketch I just made at any diameter because I cant put all the points on the origin. Any idea how to get around this? Also I'm not sure how to do the 2nd part of your post, I can create the separate body and pattern that, but how do I adjust each instance of it?
Thanks,

RE: Pattern
I think the easiest way would be to circular pattern the cut-sweep (as per Scott's suggestion) & then offset & cut-thicken a surface from each instance, incrementally increasing the offset by .005" per instance.
This will be a PITA as you will have to do it 71 times if you are patterning thru 360°.
