Help With Continous Curved Ramp and Form !!!

[Anonymous]

H guys,

I want to create a building really similar to that of the cocoon office in zurich. The spiral ramps are continous and getting bigger all the way to the top. I have no idea on how to draw this on archicad. The curved ramp in the object folder does not allow me to achieve this effect.

Another question would also be on how to achieve the outher form which follows the spiral of the ramp. How do i cut the curved wall to be in line with the spiral ramp?? Your help will be greatly appreciated!! Please Help !! Thanks...

And this is the object (made by Mirco Sorgato from Italy - UI is in Italian):

Usage: Select the Stair tool > click the little triangle (Element - Open Library Part) > Load from File Dialog Box...select "Rampa a Spirale (m).gsm" > Open.

Guys please help me on this one. I couldn't get the curved walls out using SEO as it can only substract with upward extrusion and the walls doesn'f rollw the spiral form. Please help !!!

I would create two ramps for cutting and place them on a hidden layer with its intersection layer group changed. One ramp would cut the top of the wall and the other ramp would be used to cut the bottom of the wall. I would then create a third ramp for the actual ramp and butt it up against the lower cut. That's a quick way.

Here is an example of ramp I made using mesh and SEOs.

I played a bit and made a quick step by step tutorial.

So long as the ramp spirals inside itself all the way then this works beautifully as you have shown.
But if the ramp loops under the portion above (like a standard spring and as I assume it does in the original image) then you will need to break it down into 360° rotation segments.

I would imagine you would need to break the walls in the original image into 360° segments to trim as well or even less to make them more manageable.

It looks like LinRong is in for a lot of experimentation.

With the tool that I was developing (dragon) is very easy... you can define a mesh with free point and then you adjust graphically to the contour and in section o 3d adjust the height (graphically too).
For the walls you can put another mesh, define a cusom panel (windows), rotate and adjust in the section...
