Use the Pulley dialog-box to edit the number-of-teeth around a Pulley.

The Pulley dialog-box also has this 'read-only' information:

Pulley's Pitch Circle Diameter [P.C.D.].
Tooth-Pitch [Edit the Tooth-Pitch parameter in the Motion-Path dialog-box].
Belt Length [Edit the Target Belt Length parameter in the Motion-Path FB dialog-box, or edit the sketch directly].

To Open the Pulley dialog-box

Tooth-Pitch - see Motion-Path FB dialog-box
Belt Length - see Part-Editor


If there is a Pulley, then, in the Part-Editor, its radius becomes a 'read-only' dimension - it is grey.
