Variable Pitch Helix
Variable Pitch Helix
(OP)
I'm having difficulty creating a variable pitch spring where several sections of the spring have a close wound pitch (i.e. pitch = wire diameter = .003"). SW yells at me and says I have to choose a value greater than .00393701. Anyone know if this is possible?

The end result is rather hack and can be horrible for FEA, but it is a way to communicate your intention.

"pitch=wire diameter-0.003"
make the wire size 0.0029999" and the pitch 0.003".
If you set your dimensions to only display 3 decimal places it will round to 0.003 and the model will work.
