tutorial three_attempt

After completing the pipes tutorial, I attempted to create a series of gear parts that could form into some sort of grander assembly.  

I set up a series of construction lines that were coincident with the center and the outside circle and the angle were established off of the other rays, creating a non-flexing angles, but the inner and outer circles diameters were assigned to parameters.  

 

 

Unfortunately, after multiple attempts, the geometry of the gear was not one that Digital Project approved of.

After multiple attempts, I came to the conclusion that the gear teeth would all have to separate sketches, each extruded on its own.
