How do I create a helix with varying (increasing-decreasing but nonlinear) pitch in Catia?
Hi, I need to create an helix with varying pitch in Catia. The profile, radius does not matter but I need a helix for example, first pitch is 5.594mm, second one is 6.097 and third one is 6.176 with three or revolutions. So I need a law but there is only s-type. It creates a helix which has inputs just starting pitch and ending pitch and the rest is auto calculated. I need to give every pitch individually. If I can insert a law what kind of curve should I draw? Thank you.

I thought an "Advanced Law" could be used, just like other geometry with varying length or angle inputs. But when I tried to use a Law for the pitch of a Helix, I only have 2 options: Constant or S-Type.
So, I don't know how to to this with CATIA V5.
But why would you want a helix with a constantly varying pitch?
Use PTC Creo to do it.
