See, I need the drawing to be involute so I can take this drawing somewhere to be manufactured (edm, perhaps laser, etc.). I have a program (Geargen) that will make an involute external gear in a dxf, but not internal. Can I somehow convert it in Inventor or AutoCAD? Or are there any other programs that will make the drawing?
I found an involute internal gear on cbliss, but it does not seem to show anything when I open it. All the features are grey-ed out.
Is there any way to make a gear drawing good enough to cut in AutoCAD?

This is an add on program for auto-cad, it saved us countless work when we needed a rack for the window motor.

comes with a 15 day trial, after that 69.95 it does internal, external, sprockets, racks, and right angle. Very easy to use Good luck
