Did a Crown Gear with 87 tooth gear, and 17 tooth pinion, from the crown gear demo excel file.
The pinion is easy. It is just a spur gear. Pinion tooth cutout circular array is done in Top view
The gear steps can be easy, but it did take some time. For the half tooth cutout, mirror, loft, and join, and array circular, is done in the Front view
The .3dm file for the gear is 42,129 kb. (very large)
The .3dm file for the pinion is 647 kb.
The Boolean difference for the gear teeth was done in groups of 9 to 13.
The final gear had to be rotated 180/87 degrees (2.0689+degrees), to mesh with the pinion.
Ctrl-C copy from MoI, and Ctrl-V paste into Geomagic Design (Alibre) was successful.
