development of a cylinder

hi to the whole forum, I don't know if the title of the discussion is clear, but I didn't really know how to explain. I would need help from the forum to solve a problem that could help me in the yard:
I designed in 3d a spiral staircase to be made in c.a., and I would like to make as quickly as possible the wooden docking without buying polystyrene molds. as can be seen from the attached design I extrapolated, from the solid of the staircase, a surface that is the imprint of the staircase left wrapped on the central pillar. If I could print with the plotter the surface (turned to the pillar) on the top of the sheet, I could cut it and physically wrap it to the reinforced concrete pillar after which I could mark it easily and fairly easily realize the docking. How could I do that? Thank you very much to those who will help me.

I did it with rhino and inventor but I'm sure with two miserable calculations you could do the same.
the scale of the drawing is that of your attachment.

beautiful design but I'm afraid that without the use of polystyrene a gender scale you could never do ... seen the various models of the panels that are exclusively plan becomes impossible to realize the curvature that qmc must follow a precise trajectory . my modest opinion and that using polystyrene you save both in terms of finance and as time of commissioning.

Thanks stefanobruno, too kind, as soon as I get to the office I open it.
Thank you for your compliments, but I assure you it is very feasible. It remains to be seen if the customer is good to spend to pay the trouble of such a complex realization. a similar scale I made it 7/8 months ago and came great, happy customer and ready money at work. I attach photos.

Please! I have a great experience on the yards but given the quotas I imagine it is an internal ladder that had to connect a attic or something like with the underlying plan ....so little to spend on polystyrene .certo that in the yards today as today it does everything .poi maybe I have the fixed for this type of solutions .we have to say it pero, to the forumists that raises are done after the walling, cmq I appreciate his achievements... precise and accurate work.

I still couldn't get my hands on the job you did. As soon as I can let you know.
