I am curious to know it you are looking for a spiral shape such as this

The spiral was made with a helix tool. So I think it will probably have a smoother shape than trying to drag around bezier handles.

 

The flat spiral at the base (outer side) is 4401mm. So it is 1mm over what you show in the original post

The overall height is 4413mm. So this is 23mm over what you show in the original post.

The thickness of the wall is 101mm

So if you do decide to use a spiral for the plan view shape of your curved rake wall, then to dial in the shape, and length you want along that spiral, you're going to have to do a little bit of trial and error or number of iterations to get what you want. It’s a process that might take 5 or 10 minutes or maybe even longer to get that particular shape and length.

In the video below, I begin the process by adjusting the START RADIUS. Later on in the video I dial in the END RADIUS.

You could see in the video that I don’t move at the speed of light. I’m not a fast user of any interface now days. Would be terrible as a CAD draftsman.

So as this is a realtime recording by a slow user, it is feasible for anybody to do this in the same length of time if not faster.

Now even though I am slow at the keyboard and UI, I am still able to get a shape I like and a length of 14’-4” (along the spiral) in about 4-1/2 minutes

Once I have that dialed in, in the dialog box for the Helix-Spiral, I would DESELECT the FLATTEN, and do as shown in the previous post video.

All in all, the 2 stage process could take as little or less than 10 minutes to come up with a 3D model of a curved rake wall.

 

The basic procedure in the below video is —

Use the HELIX-SPIRAL tool

UNGROUP to see the length

UNDO and try again

Whenever I look at someone's problem I tend to answer, as to how they are doing it.  They have a methodology in mind and it does not introduce noise.  But, there are lots of ways to make this. 

In the video below, except for the initial flat curve, the new curve is made without being handled.  All Object Info Palette.  About 50 seconds to make the spiral curve.

Hi Paul,

 

Yes there are definitely a number of ways to do this from looking at everything in this string.

 

It’s hard for me to determine exactly what @rouan is looking for as I didn’t see a good plan view of the curve he wanted.  It could be something that looks kind of like a spiral for all I know but is more or less, just a freehand curve of sorts.

 

I don’t know the underpinnings of how the Helix-Spiral tool works. But to me, what I like about the tool is it appears to be making a beautiful Logarithmic Spiral. Whatever it is, it is something that I would personally find time consuming to try and make by dragging handles. In my case I figure, leave it up to the computer to do what computers do better than me.

Hi Steve,

I don't think it was an exact mathematical spiral.  The original curve was quite disjointed.  They should be able to make it now.  

 

You showed some nice work above, although I never use deform tools, except in animation.  That is where their real strength is.  Deform tools tend to be the end of the line and that seldom works for me.

Thanks Paul,

 

Your videos are always great to watch.

 

I agree with you on deform. It really is not something I am going to use very much either as in the case of what I did above. It really was a freehand way of going about it. Bend on top of bend with no coordinates typed in, blah blah. You know what I mean. No precision with that example. But, it was the first thing that popped into my mind, so I went with it. LOL

 

The second method was something I played with first in Plasticity, and then figured how to do it using Vectorworks.
