Create A Spur Gear Help

[basty]

Hello everyone,

 

How to draw a spur gear in autocad 2014?

 

Someone told me that it was made using the spline tool.

 

But the spline curve is not similar as involute curve, they are different.

 

Please someone help me how to draw involute curve and a spur gear technically (technical drawing) in autocad 2014.

 

Or maybe the involute has an equation and was made using additional .lisp programming.

 

If yes, what is the equation and how to create the .lisp?

 

Please help me.

 

Thank you
