How to recognize gear teeth profile?

Here you go Anoop, FeatureWorks didn't work with this one ironically but not surprisingly ...
But I was able to recreate the basic shape by remodeling it with the imported body as a reference.

I think you have to use the mechanical mate feature and click on the centre axes of both gears. But I might be wrong. The tutorial files will cover gear mates definitely.

Just open FeatureWorks and click on the green button.
It should recognize it as an extrude boss for spur gears ... if not or that's not what you want, post the part.
