I can key in a math formula in the 3D program I’m using, which I’ve never done before. I’m searching the web for the handy formula that will just generate the correct coil, but haven’t found it yet.
… does your”helix” command have an option that’s something like “around curves”?
If so it might save you much time if you draw the wire that runs through the core of the coil as a flat circular curve first and then tell the software to wrap the helix around that curve. Hook it all up and “pipe” should do the trick.
