3D Pattern stuck a 180 degrees

It does. Use 'copy -dependent' to copy the feature or group of features (I do gear teeth like this) once, rotated through the correct index angle about the centre axis of, well, whatever. Then pattern the copy (there's only one driving dimension for the copy) and hey presto: all fixed. Don't ask me why.

The other that I've seen frequently is related to the way Pro/e makes circles ~ as two, 180 degree arcs, from zero (@ 3 o'clock) to +180 and to -180. Maybe that lets them avoid double bookkeeping every point on a circle by its positive and negative value (+90 as -270), then using plus and minus as purely directional indicators, clockwise and counter clockwise. In any case, in past revs, features referencing a circular edge, especially those with an arc segment created with 'use edge', often couldn't pattern past that that break at 0 or 180. Even now, in WF2, when you use an outside cylindrical surface as a sketch reference, it picks only half the cylindrical surface, but it shows the reference as a circle. And, using the Axis pattern, it has no difficulty patterning a full 360, or not that I've experienced, so far, even with surfaces. If you still have trouble, try sketching with referencing circular edge or cylindrical surface, just an axis in the middle. Make an arc, using the axis as the center, the same size as the o.d. but not locked to the edge. These are just some of the ways to eliminate trouble before it starts.

The angle needs to be part of the feature. So for your sketched curve, you should do a make datum for the section references with your initial angle. You should than be able to pattern that dim successfully.

Jas> I was creating a 3D part in Pro-E WF and needed to pattern it 360

You can also use construction circles concentric to the reference circle. arcs then sketched on top of these are more reliable than ones made with 'use edge'

Thanks David, I'l try the axis pattern functionality - as usual, I was just sticking with what I knew.
