The difference is that their teeth are at some helix angle to the. Could you help with this? With the correct inputs, will the resultant part be an accurate representation so that it could be used to create the mold? Thanks for your consideration. Helical gears, like spur gears, are cut from a cylindrical blank and have involute teeth.

I am having trouble understanding how to convert the helix angle into the inputs of the coil feature. Based on your comment "I think I would have used coil", you must agree. I have a strong belief that this strategy of using the design accelerator to create the helical gears, and then exporting the tooth profile to create the accurate model is the correct way to go. Now I am designing a pair of helical gears. It is important for me to have my models be accurate as they are directly used to create injection molds for manufacturing these gears. I have used these exported profiles to create spur gears successfully. It is my understanding that gears generated by the design accelerator are rough approximations of the ideal, and that the gear tooth profiles exported from the design accelerator are precise representations.
