How do I split faces that have been stitched intelligently by Solid Edge?

Screencast for the issue: http://screencast-o-matic.com/watch/cIjIXDVgId

 

So I was working on a part, I had two concentric surfaces... one was an arc based surface and the other was a cylinder. They had different radii, but as I was fooling around with dimensions, they became equal. As soon as they were equal, SE stitched them together into a single complex surface. From there I was unable to detatch them from eachother.

 

I'm just curious if there is any way to detatch these (or not attach them at all!) in the future.

 

Not attaching them at all would have been best, as Mastercam was unable to detect the loop properly for machining without me adding in arcs at every stitched point.

 

Thanks again guys, you all have been such an excellent resource. Smiley Happy

in Synchronour we dont typically have to split the face since we use the region concept.  If you draw a sketch line it seperates areas.  each area is its own region and can be modified as such.  If you do need to use the split face command there is such;   you can easily find it by using the command finder "split"  this will show you a few options.

Hi, what do you mean by "region concept?" Thank you

Luke,
The function you've come across most people see as a good thing. If you made two surfaces the same radius and they were touching each other like that, you'd be kind of disappointed if they didn't merge. It's a function of Parasolid and the NURBS topology.

Still, it's one of those "quirks" of direct edit methods, that once you merge two faces like that, you can't really "unmerge" them. The easiest way to make the top area a different radius again would be to cut it down, either with an extrude or a revolve.

There are some other things you could do to "cheat" it, such as the split Matt J talks about, or keep the upper area as a separate body, or put a tiny groove between them, or make one just a few .00001 off from the other. I wouldn't recommend any of that, though.

MLombard, I can certainly see how this would be excellent in many circumstances. Smiley Happy I was hoping there was some kind of face relation like "don't stitch these two faces, ever, NEVER!"

Thank you both
