First I congratulate you on your success in business. UG is a VERY expensive and VERY VERY capable program for manufacturing and when your business is at a point to require the high end software you're doing something right. I was an applications engineer for a local reseller for a while. I used UG NX in mold making and 5 axis CNC programming. Minimum cost of the multi axis CNC capable and assembly design in UG is in the $30k range. Probably another $5k for verification software. Don't forget another $10k for a post processor. Don't fart too loud near the software or it'll tack on another $5000 just because. And figure 10% per year subscription.

That being said... You can't go wrong. I much prefer the UG interface over CATIA.

One thing I haven't done in a while since I don't use Mastercam anymore... If you want to verify actual G-Code you can do reverse "post process" a g code and turn it in to geometry. Another thing you can try that I've had some success. Import a gcode in to MS excel, clean up the junk so you can isolate the XYZ coordinates, and import the file as a point cloud.

For my business I use VX and the much maligned BobCAD.
