Great explaination on that scaling issue. I figued this was the case your explaination reaffirmed. Thanks!
On the "contour from scratch" I just selected the top edge of the wall and used SU's contour from scratch. From first glance it seamed to work fine with a little clean up.
I will look at it again.@dtracrh,
My walls would be titlted out ward as it follows the path. However, I would be interested in
what method you chose to arrive at your conclusion. -

......lapx,
Now I see what you mean, not "contour from scratch" (and not "from scratch" either) but "From Contours".
And you are quite right, that works perfect when no height corrections are needed.
When you have both the inner and the outer curves selected (spirals in scene 4, without their connecting edges at beginning and end) and apply "From Contours" you get a very good result that only needs some cleaning up.
I guess I was to much focused on "what if height corrections are needed for horizontal cross sections at the top of the wall". Even though the curves are slanted it's best to apply "From Contours".
(Leaving the face in scene 3 > 4 will give bad results when applying the "Smoove" tool)
Well, as I said: "maybe I can learn something".
Thanks for the suggestion.Wo3Dan

Thanks for clearing that up for me

<-- Why 
You drew my attention to something about the sadbox that I overlooked.

So that's at least worth a 'thanks' to you:!:
cheers,

Hi lapX
Here is how my example was put together.
I used your path and welded the spiral portion first.
The spiral portion was then extruded up using the vertical line of the path with the [extrudeline]with vector ruby.
This face was then extruded horizontally using the [jointpushpull] ruby.
(the keep face option found using the [tab] key was selected and there it was.dtr

Thanks Guy's, not to get to far off base but how come autocad, desktop and revit don't have a forum like this? They could learn a lot from this place.
cheers! -

It's overorganized (too many subforums with overlapping topics) but overall not too bad. I just learnt a lot about dynamic blocks.Anssi

Hello Jean,
How would you get your method to rise from a low point to high point. One advantage of your solution is the wall is same thickness from top to bottom.

lapx,
In this case smooving the top will not work.
Intesection with a vertical cone (preferably high poly) will do the trick.
Place the cone with its vert.axis right in the center of the bottom spiral.
Check if the slope is UP all the way to the center after intersecting, it should be.
(Otherwise undo and reposition the cone a bit)Note that there is a big difference between Jean's slanted wall and the previously uoloaded ones.
His wall is equally slanted all the way along the spiral.
Ours were going from 'slanted much' to almost vertical near the center. Due to scaling.
(It depends on what you need)
With Jean's wall go for the cone-intersection.Wo3Dan

Promise not to laugh?
I can't figure out how you draw a spiral like that to begin with.Hey! You promised not to laugh

Gidon, i only just figured out how to do, it took me blody ages!
Anyway, i do it by making a load of construction lines all parallel to each other and all on the same plane. I then draw a circle centered on one with the radius being the distance to the next one. I then split the circle in half with a line perpendicular to the construction lines. I then make each half of the circle a group. I then scale one half untill its touching the next construction line (scale using a corner handle). This is follwed by moving a copy of the other half in to line with the stretched end of the last one. Scale, move copy, scale, move copy etc untill you get a spiral as desired.
Im sure theres a much more elegant method for doing it, but this way gets it done.

The easy way is to use the K-Tools script, the spiral is slightly different from the one you get from successive quadrants - not that anyone would notice.
