Maybe concept like this
Draw helix by P Brawn explode it (because it is a group) length as you want (
Draw 2 Straight lines Curves normaly in your case similar (minimum 2 Segments) inclined as you you want
In your case redraw 2 spirals against the 2 lines a & d
Call Extrude Edge by Rail by TIG
Click b & Clik c are on the same curves
Et voilà

Ps In fact your model is 4 spirals

You can draw a rectangle, divide it on the diagonally a bunch of times. figure out how many degrees around total the finished paper will be. The yellow one is about 28 sections bent at approx 15 deg. Bend in at a bigger angle alittle as you go will tighten the spiral at the end.

Again Extrude by 2 rails
2 Spirals, 2 arcs
Just increase the number of turns of the spiral and adapt radius size for have that you want

Why not use shape bender?

I think shape bender is more likely to be closer to the original paper size and shape.

OK gilles I have to ask, what IS that avatar supposed to be?

Pilou you have to say how you made the spiral.

With FredOscale Free bending tool. I just like using it for the fun of it. Way more fun than doing my taxes.

Start with rectangle. Make component. Put another rectangle vertical along direction of curl (I drew corner to corner) for setting the rotation. You have to bend a portion (I used 1/3). take off the straight portion (using edit component, choose flat face and edges, make component, cut, exit component, paste in place), bend that-- and repeat for total of three or more times, because you can only go 180 in each bend. Probably faster other ways? But this feels more "realistic" and you can adjust procedure for the curl you want.You explode and rejoin the portions at the end.

"distinguished"? Now I'll have to grow a mustache.

Manual SU by my above method. I'm sure it's a little slower than fredoscale and probably a little harder. Took about 25 min. and I should be doing something else, but this is more fun.

you have to say how you made the spiral.

Like the first post with the draw Helix
Draw any Helix / Copy Move then Scale it

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.

Re: Help! How to make a spiral like a paper?

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?

Re: Help! How to make a spiral like a paper?

#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.

Sly:
#5 draw the sheet with circle tool set to 4 segments ( if you want a square sheet )

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.

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

Re: Help! How to make a spiral like a paper?

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.
I take the slow, deliberate approach in my aimless wandering.
