how to generate a flat footprint

[loky121266]

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 think with acad, it's a little dizzying. there are programmes of development which would do for you, now I do not remember their names, not being in the field; but surely in the forum you will find more precise references.

try to put the same question in the "mechanical" sector.
