Pattern within a sketch, Solid Edge.

I want to create a circural pattern within a sketch. When I try to do it on the figure shown, it only creates an circle. The "tooth" is not patterned. Thanks

I would just create one 'tooth' in the sketch, then instance the rest of the features around a datum axis.


You can create expressions that define the pitch, diameter, number of teeth, angle, etc to control the instance...changing the number of teeth will automatically update the rest of the variables. Use the expressions 'angle' and 'teeth_number' in the instance dialog.


For example:


angle= 360/teeth_number


circ= pitch*teeth_number


dia= circ/pi()


pitch= .5


teeth_number= 18
