I was using X3 previously. Never had a siginificant problem there. But now about 50% of the time my objects arn't combining or trimming properly. Reversing the curve direction worked, although it's a REAL pain in the butt, not to mention that I never had to do it before. I did however export everything as .EPS and reimported it and it combined fine then. I am guessing that something in the .EPS filter corrected the issue. Still though, this is a HUGE issue for me. I would hate to think that to merely combine some objects that I will have to export and import them.
