Subtract Command Problem

[dkadz12]

I am using autoCAD 2006 and have run into an issue when I try to subtract a sold from another solid. I keep getting an error message that reads Inconsistent Edge-Face Relationship. For some reason this is not happening anywhere else on my model. Does anyone have any ideas that might help me out?

Thanks!

I've had that before and it seems it was usually that I didn't have them aligned like I thought I did. One was slightly off-plane or something. Or the overlap wasn't actually what I envisioned it being, so there was the situation where the subracting face came out of contact with the other body. I've gotten to where, if possible, I make the solid which will subtracted from the main object longer/wider than necessary, since it goes away anyhow.

For instance, for the simple case of having a 6" dia X 12" L cylinder that I want to make a 2" dia hole through, (a the centerline, quadrant to quadrant, perpendicular to the axis), if you make a 2" dia X 6" L cylinder to do the subtraction with, you might get that error. But if you use an 8" L X 2" dia cylinder and let it stick out on either side, you won't.

Other times, I've had a drawing error where a face wasn't exactly as I meant for it to be.

try to extrude one of the solid into the other one and subtract.

Thanks, both of these helped!
