How to draw simple gear teeth in CAD?

[LinearMotionFan]

Hello,

I am trying to draw a gear with simple triangular teeth.

I know the number of teeth and the major and minor diameter of the teeth.

How do I easily and accurately draw the teeth around the circumference of the gear? I found a lengthy article with all the math to draw fancy rounded teeth, but is there a simple method for basic triangular teeth like this?




Thanks!

Draw one tooth at 90° to the center and use a polar or circular array to do the rest.
