I need to know in detail, how to create a rack for a spur gear? Answered

I have the spur gear, but i want to make cuts in the rack using the shape of the spur gear's shape, but i'm stuck in how to get it up and running.  :( 


Take some shape lock and melt - run the spur gear over it to produce the rack.

Do you mean MAKE it , or just DRAW it ?
