I know that there was a way to do this before, but I haven't used the Engineering Reference for a while. How do you get the engineering reference to use english units for the gear designer. I want to get away from having to input module and use diametral pitch. I know how to convert, but it is a pain.
if I understand your request, you wish to use english units in Engineering Reference. I do this by going to ApplicationButton->Properties->FileUnits and change the length unit to in.
Not sure if that helps but hopefully it does.....
