Habbe, I like your comment that SolidWorks is something that Solid Edge is not. I think you may be mistaken as to what Solid Edge ie - it is not Edgecam. As you may not realise, Solid Edge and SolidWorks are built on the same kernel. This means that they have exceptionally similar capabilities. They are both fully funtional 3D modellers, each company will claim that theirs is better, but they are very similar. They do have their specialist capabilities, but as to normal assemblies they have the same capabilities.

Chris007, As to the actual problem, making gears accually mesh and work is difficult. Habbe's suggestion to look for a file that does it already is a good one. I suspect that you will not have much luck. The upgcomming new release of Soild Edge has some new fuctionallity it this area, and I suspect that means SolidWorks is not far behind. wether these changes help you is a different matter. I would be interested to see if you made it work.
