So I have this assembly of some concentric parts - basically it's a hydraulic swivel. I have created a configuration in which I have a couple of Cut Extrudes to cut through various parts of the assembly - some parts are cut to 180 degrees and others are cut to 270 degrees to show all of the bearings and o-rings and all that.

Now I want to rotate 2 parts in that assembly - I'm working on just 1 right now to get it to work, then I'll go to the other one. I set the plane of the part I want to rotate to 0 degrees with the top level front plane. I tried to apply a mate change from 0 degrees to 180 degrees over a short time period (a few seconds). I then hit the "calculate" thing and waited for that to finish, then hit the play button. Nothing happened.

I think that what is happening is that maybe the part is rotating but that my assembly section cuts are "dead zones" that keep sectioning the part as it rotates - in other words, I might need to rotate the assembly section cut, not the part itself... But at the same time there are some holes in the sides of the part and they aren't moving...

In the help file there's a section called "Using mates in animations" and they have a little movie in there showing three "oven knobs" rotating out 90 degrees, at the same speed, then coming back at different speeds. This is almost exactly what I want to do, but with my assembly section...

Is there any hope?

Thanks.
