development of helical sector

[windreef]

Good morning
I should make the development (for laser cutting) of a helid sector.
in the sheet module I did not find the helical command, so I always created it in the sheet module but with 3d model command. Of course now it doesn't make me the flat model.
What passage do I miss?
Thank you very much
I attach the file

I have the 2019 version for which I can't open, but I vaguely imagine what you mean and tell you that being a processing of "snervation" sheet and not of simple folds the software fails to develop the figure. I have also struggled in the past with similar solutions but without success, the thing that approaches reality and directly make the model slowly building it starting from the size of the ellipse. measuring the 3d model with curved length of the sides of the helid and drawing it brutally. I try to post an example if it can help. Obviously then in the workshop they will "become" to adapt the development to the finite form.
