Help! How to make a spiral like a paper?

Super cool! You guys just save me!

It's a dog.

I'm confused. I see what might be a tail, an organ, and an orifice but at that point my imagination can't hack it.

               **EDIT:** Now I get it. Before, I could not hear the splashing.

Great tips on the model, folks. First I'm going to try Pilou's 5 second method. Be back in the morning sometime when I finish.

I'm back but for me the use of TIG's tool is not intuitive. I don't doubt that that is more a reflection of my limitations but one might need reminding that TIG's tool needs curves for the rails, as Pilou mentioned. So you need to draw even a straight edge as multiple sections or divide it and then weld it into a curve.

Very conceptual avatar!

Thanks for learnin' me a little, after which, for me, extrude edges by rails works best, simply because I could not make the length of the helix and the diagonal to match so shape bender had an annoying error (the little projecting tab). How to make these equal? Note also the disagreement about the length of the scaled helix curve info=112', label=245'. I assume the scaling threw a wrench in the works?

#1 draw the path ( helix )
#2 select it, open entity info to get the length
#3 draw the line the same length
#4 draw the diagonal sheet the same length
#5 draw the sheet with circle tool set to 4 segments ( if you want a square sheet )
#6 erase the diagonal
#7 group the sheet
#8 run shape bender.....wait....
#9 resize the model with tape tool. done

it takes five minutes.

Thanks for that.

Perhaps that method it is more accurate than 'extrude edges by rails' even if a little slower.

If your paper is square it's fast as you already have the diagonal.

Anybody tried Spirix on this? I am not sure if it can be applied here. Some more info, I think is in a thread back about 4months. As far as I know, the author doesn't post here.

Heck, man. That thing looks real nifty.

I like your way because it has the rotated sheet (corner up). I cannot do it faster than EEbyR, though.
