Inventor Question about Opening .stp files

Awesome, Thanks for the link. It's just as good as the original.

While I have your attentions, I just have one last question.

I have been wanting to make my own gearbox for a couple of days now, but I'm just kind of lost as to how to approach this. I guess the main thing that is throwing me off is the distance between the center of the gears.

I was tempted to say that the distance between the center of gears would be equal to the inner radius of the gear + the outer radius of the other gear, but I know that gears don't sit tight into each other.

Then, I was just tempted to eyeball it, but that's not a "correct" workflow and it's not something that I wanted to depend on.

Thanks for any help.
