Is it possible to set the pitch of a propeller?

3D Design Volume Model

Hello

I want to make a propeller whose pitch would depend on a predefined equation. Namely that the pitch would be related to the diameter of the circle on which my propeller takes its source.

The goal is to have a constant ratio between my pitch and my diameter, a ratio that I manage by my equation parameters.

Thank you.

Hello

Yes, it is quite possible. What is the problem?

I can't assign a parameter to my step, I can only give a numerical value.

I would like my step to be related to an equation that depends on the parameters already entered in other sketches.

In fact  the trick is to create the propeller by validating it, then by double clicking in the 3D, you see the pitch appear.

From the dialog box, you can add an equation.

Here is an example found on the internet:
