Gear Generator Calculating Wrong

[acrease]

It seems like the gear generator is not performing the correct calculations when I enter a diametral pitch. The gears that it is creating are an order of magnitude off. First of all, "Diametral Pitch" has units of 1/length, and in the gear generator the units are in cm, which is confusing and not true. It seems like I can only obtain the correct gear that I want by entering a diametral pitch 10 times its "correct" value.

Gears I've work with are normaly specified in DP (Diametrical Pitch) for imperial and M (Modual) for metric. To get metric gears from the gear script you need to divide the module by 25.4 then divide by 2.54. So if you want a 1.25 module gear with 10 teeth it's (25.4/1.25)/2.54 = 8. The gear generated will have an OD of 15mm and the pitch diameter will be 1.25x10.
