I have problem with toolbox, I want to make a metric spur gear with a specific module (2.125mm) witch is not in the pre-determined modules available. the problem is when i try to add this mesurement. it appears that toolbox will not allow me to type ''.'' (as in 2.125) when i do, it tells me to type in a valide value and doesn't allow the custom mesurément to be created. I tried to type "," instead. it worked but the value results to be 2125 instead of 2,125 witch is not better. I tried the classics of closing and reopening everything, restarting my computer many times and nothing changed. starting to lose my mind on this can someone help?
