I'm sorry. but I've tried my best to understand complex profile since a long time ago, but I can't. could anyone help me to show the steps using complex wall for my roof?
There is another way to get what you want but it is not modeling with ArchiCAD only. Rendering with Displacement materials will do the job better.

Unfortunately, the rendering engines in ArchiCAD can not process displacement materials.

Below is a link to some scripts for displacement roof materials if your interested.

http://www.digitalxmodels.com/product/detail/442/3d_model_Displacement%20Roof%20Surfaces_maxscript

You need a rendering engine like Thea, Maxwell, Maya, Vray, 3dMax, C4d,etc... to use displacement materials. Displacement materials not only reduce the amount of modeling that is needed but it also allows you to add detail to your renderings that is not possible otherwise.


You can do a very good job of modeling the tiles with the Conoid object. It is very adjustable on the fly in 3d for tilt, thickness, taper, etc...




Just for fun, this model is made using only the conoid object and a mesh for the roof. It did take some rather clever modeling if I do say so myself.
Because the ridge and hips are curved, every section through the tiles will have a different curve and must match the one on each side of it. I am keeping a few secretes about how to do this.









Don't let the amatures discourage you. You can model this building in ArchiCAD very well, and with out .gdl scripting.

It's all about the dougong. 斗拱

Complex profiles may seem overwhelming to you at first but they are quite simple when you actually start working on them. To illustrate, the image posted yesterday took less than 5 minutes. Essentially, it's a two step process:

1. Draw a cross section of whatever you want to create, in the profile manager. In this case, one half of your roof from eaves to ridge.

2. Draw walls along the length of your structure using this profile (see the third image in Eric's article for how to choose which profile).

After that, you can move them in section or elevation to place them correctly and use SEO (Solid Element Operations) to trim the walls to this "roof".

Let's face it ArchiCAD at the present state is not 'ideal' (sorry for the terminology used!) to model this kind of sculpture.....SketchUp will do much better job
No hard feelings, just my opinion!

I have to say that I prefer the real to the ideal when it comes to getting things done.

The roof in question is difficult to model in any program. I am familiar enough with SketchUp to know that it would not be so easy as you suggest and once done, not so easy to revise (though the new component features would help).

The way I would do this in ArchiCAD is much as I would in SketchUp which would be to create some modular assemblies and put them together to make up the roof as a whole. The trickiest bit would be the curvature across the eaves and ridge. This might require making the assemblies into library parts to allow for the rotation. This is a bit tricky in ArchiCAD but very difficult in SketchUp.

Take a look at OBJECTiVE. It provides tools for profiling, rotating, bending, and cutting objects, and I think it will make this job a lot easier. I'll provide an example, and can show more if you wish - referring to the attached image:
  • 1. The easiest way to set out tiles fitted to a curve is to set them out in plan and then tilt them into the model. I'll use the standard conoid object, place one, and use OBJECTiVE > Tools > Rotate to tilt it on it's side.

    2. Then I used the standard Multiply to array the object along the arc of the roof where the section is cut.

    3. Then I rotate the tiles back into the vertical plane using OBJECTiVE > Tools > Rotate.

    4. You can also use OBJECTiVE's Split tool to cut the objects where they meet intersecting hips or ridges (simply trace the cut line over the objects).

    5. The finished array of tiles in 3D.
This only took a matter of seconds to complete - the entire roof could be done quite quickly once the basic setout dimensions have been established.

...or use Objective of course! I begin to wonder if there is anything it can't do 😉

Ralph, how about voice commands so we can just tell it what we want and have it model the building for us
