I search around and did not find this question on these forums.
I am trying to create a swept "cork-screw" (I'm actually using a rectangular closed profile but we can stick with a circle at first) that starts out thick at the bottom and ends at a sharp tip at the top of the helix. I was hoping I could use Equations to vary the diameter of the swept sketch as a function of the Z coordinate, but I cannot figure out how to insert the Z coordinate into the equation. Solidworks shows a file property variable "SW-Pz" which I assumed meant "Position on Z" but I get a syntax error and the equation fails. SW help menus aren't very helpful as well.
Any one have tips or a different method? Thanks in advance.
