Can't draw small gears

Can't draw small gears

Can't draw small gears

(OP)
I'm having dificulty drawing up some small gears I need manufactured for a cryogenic system. I'm fairly new to solid edge and I'm using the solid edge rack and pinion designer in SE V.20, and I want to draw a module 0.5mm gear with 20 teeth, but keep getting the error "Pinion tooth is short and has zero tip thickness".
Can anyone tell me how to overcome this problem (other than by reducing the pressure angle)?

The designer will happily design a 20 tooth module 1 gear, so all I really need it to do is draw the same gear but half the size. An alternative would be to draw the mod 1 gear, and scale it down. Does anyone know a way of scaling a part? Short of individually changing every dimension.

Finally, can anyone confirm that solid edge generates an accurate, true involute tooth profile? I'd like to be sure before I send it to the workshop.

RE: Can't draw small gears

You can scale it down by inserting it as a part copy into another part.
