Hello cats252,

Many times (regardless of the CAD system) you can eliminate a modeling error by undoing the operation just prior to the operation that is causing the error. Sometimes problems occur that do not show themselves until the very next operation on the model is attempted. It's easy sometimes to be missdirected into believing the problem is with the attempted operation and not the previous one.

So.. if you are getting an error, try undoing back prior to the operation that preceeds the one causing you the error. Then try a different appraoch if possible or tweak some operating geometry, then try again.

Good Luck.
