So, I'm interested in making a spring in Inventor Mac (yes, I know, the free version). It seems that it is not possible. The revolve functions dont seem to support it and further, there is no coil option. Way back in the day I did this manually in Autocad and it was a big hassle. It seems the Pro version of Inventor had this feature. Is it planned for the mac version?
You are correct, there is no coil command in Inventor Fusion for Mac.
Fusion 360 will have a coil command and runs on Mac.
