After working with SW for a while, the "zero geometry" error pops up often enough to be a pest. Someone else who uses SW tells me it's because SW doesn't know what you want it to do when that happens, leave material or take it out. This person told me the only way around that as far as he knows is to move one of the dimension about .001 (a very small amount) to avoid that particular error. That's what I've been doing and it does meet my needs but is that the only way around this error?

Norm,
This sometime happens when you fill a void in a solid part to it's exact dimensions. An example is a web to support the top and bottm flanges of a C-shaped beam. If you use the inside surfaces of the C-beam to convert entities to your sketch lines for the web (or rib), you will someimes get the "zero clearnce geometry" message when you attempt to extrude. I believe the advice you got was correct. I have found that if you expand just one line your profile into the body of the C-beam, no matter how small the intrusion, the web extrudes normally.
Regards,
Dennis
