conversion in solid part of these particular steps

[F.Devis]

I would need to convert a solid part of this type having only the step. The design is a downside. Thank you.

Actually, you don't understand if the axes in model 3d are random or if the model really has a propeller twist.then, assuming that it is a cylindrical calandrate, I don't think it can develop as it is because solidworks develops only two things:
- sheet metal sheets (which are sweeping or simply bent handkerchiefs)
- there must be a straight flat flap that will remain the master of explanation (it should be added to the model)

I'll explain to you that it should be tempted. as I have freecad I can't try it directly, but I'm afraid it can't work because it's not cylindrical.
the system that can be valid I think is the reconstruction from scratch of the model, so you need to redefine the geometry and try to see if a subsequent development can go out, using a straight sacrificial flap.

I fear it is not developed in a classical way.

I tried with modeling v20 and couldn't, even with the trick you indicated.

I had the doubt that it was unfortunately so:

function insert bending
selections aboardbending tolerance 0.5 or similar
you will have your developable piece

 

[MassiVonWeizen]

I was wrong. not bending tolerance, but k factor

thank you all now I try
