Hi guyss.. i'm facing another problem with this building..

I modelled the circular tube using the latest fredo curviloft plugin. But when I tried to slice them, it says that "there is no volume to slice"

Same things happened when I tried to use Tools -> Solid Tools -> Substraction
it said that the geometry is not solid.

therefore, I tried to use the intersect with selection method (1.jpg) but as soon as I press the intersect button, the program crash, probably because of the number of geometry that i tried to intersect.

What Im trying to do is to make the inside of the building (offset the tube at the beginning to create the interior facade.
Or is there any better way to model the inside of the building? Because before with the slicer tools Thoise hundreds of facade will still joint with the interior, and what I want is to distinguish the facade with the inside of the building.

I'm sorry but one more question.. how to make these sharp edges into smooth curves like the one in the image below

OH MY GOD TIG.. ur plugin is just simply friggin awesomeee.. i've made it in less than a minuteee... THANK YOU SOOO MUCCCHHHHH......
(I wish i've found this plugin a week ago) sigghhh... but still.. THANKS HEAPSSS...

Hi TIG,

That looks a very useful plugins. where can I download it?

If I could make the 3d sculpture similar I think I might be able to use the section plane to cut through and get the desired plan view. Or is there any other way?
perhaps I need to use AutoCad, and i've tried to browse around the tutorial but still cant find any useful tools to draw these crazy lines.

Is there any sketchup plugins out there that might be able to help me? coz these lines is pretty much similiar with a countour lines but with constant disctance (approx 50 cm each riser width)

Hi Gaues, and TIG

Thank you for the reply. but the problem with this staircase is that the staircase is part of the facade.

It is true that those staircase work similar as a contour line.
BIG program was to substract a circular tube around the circle, and use the space within as the staircase.

I've tried to advanced copy a lot of squares layers to the substracted cube, but still cant get the desired controlled of the cube.

Hi guys, this is my first post.. I'm just wondering how to model/draw an unusual curved staircase (link attached) by Bjarke Ingels Groups for TEK building Taiwan in Google SketchUp.
I've tried to use the copy along the path, but still cant control the interval along each riser of the stairs. All possible solution and advice is very much welcome and appreciated. Thank you.http://static.dezeen.com/uploads/2011/02/dzn_TEK-by-BIG-25_1000.gif
