How to create something like this (klein bottle house)

[Anonymous]

Hello,
I am doing some more modeling inside the archicad, and I was wondering what would be the best way of creating something like klein bottle house
klein bottle house

Maybe using a roof tool for every planar surface, that is too hard and paintfull I belive.. Any more ideas?
Thank you in advance

This kind of geometry is very difficult to model. I worked with Michel Rojkind on the Nestlé project for which we created some custom parts and had several advanced users banging on it. The really hard part is trying to close the shapes without a lot of triangulation (or any at all per Michel). There really is no easy way to do it that we found. I would suggest that you try sloping/slanted walls trimmed at the top and bottom as needed with roofs. The specific techniques have to be adapted to the particular design.

I'm sure there's an OBJECTiVE solution.

One very exciting method that I've been using recently is the SEO INTERSECTION...

1. Create a PROFILED WALL that is the cross section of the pointy roof element.. Don't work that it's a rectangle in plan...

2. Create a SLAB that matches the PLAN VIEW of the pointy roof thingy, making sure it "engulfs" the entire section of the profile...

3. Use INTERSECT in the SEO palette... (slab is the target)

4. I don't know the exact shape you are looking for, but with the concept, many shapes are possible.

5. Leave the SLAB OBJECT in the visible plan mode and put the PROFILED WALL on a hidden layer. It's easier to view the plan that way.

6. In addition, this new geometry is using the SLAB element, which is a solid, so it can, in turn, cut other walls that run beneath it....

If you give it a try, please post your results...

OBJECTiVE can do this. It's $300 US for a single license but for this kind of modeling, it's worth it.

I had to model a simple slanted filter sometime ago and yesterday I had to revisit the job. What I had done previously just looked like junk. Never liked the output but the customers seemed happy. Since then I've bought OBJECTiVE and really only used it for a decent rotate tool and a couple of simple shapes. I thought this might be a time to try OBJECTiVE and fix my mess and inside of half an hour I had modeled the filter perfectly and had it rotated exactly. But I can see how if I knew what I was doing it would have took me 2 mins with not good output, but perfect output.

I'm starting to become convinced that if you have to use ArchiCAD for anything other than standard construction or if you're not a GDL guru, then OBJECTiVE is next to mandatory. You definitely get the feeling these should be base tools in ArchiCAD.

Now where's my endorsement discount?

You should check out this thread. Maybe there are some pointers there.

I would also consider the Mesh Tool for some of these shapes.
What is good about the Mesh is that you can create a user ridge. It can be a line and you can specify the height of each of its two endpoints.

Hi,

you can use the mesh to roof add-on too, for some parts

its free and you can download it from here: http://www.graphisoft.com/support/archicad/downloads/ac14/INT.html

Model it like just like you build it and try to use only anatomically correct virtual components as much as possible.

In other words don't settle for modeling the walls as a blob and then try to figure out some way to apply a texture or something to make it look real.

If the exterior is clad, model each panel...that sort of thing.

As always, how you model it depends entirely on what you intend to do with the model.
