Gear generator from existed parameters

cherish

Hi all, is there any one used to design by using Inventor

There's a bit trouble for me when build model of pinion from table of parameters as picture below, I hadly know exactly which parameter is equivalent with abriviation in "insert ifeature", certainly not all parameter, just a few as modulus, pitch diameter, refence diameter, base diameter.... but will be the best if showing all input into insert ifeature




Please don't laugh at me, i really don't know, moreover, which grade or value of tolerances we should use with center distance 331.494 mm as in attached picture.

Thanks for sharing if any
