Model complex triangulated surfaces

[Anonymous]

I am trying to model this object in ArchiCAD.

I have already done it in Sketchup and have exported it as a DXF to create an AC object out of it. The result of this process can be seen on the image attached.

Now, I need to add thickness to these triangular surfaces so I can add doors and have a good 2D representation.

What tool should I use? Slanted walls, roofs, shells?
Any idea how this should be done?

Thank you for your help and time.

This method seems good but I'm having trouble with connections:

On the attached picture, brown triangles are slanted walls and red triangles are roofs.

The line of intersection between 1 and 2 is where it's supposed to be but I can't get rid of the upper part of the wall. It should be cut off by the roof. SEO doesn't work in this case and the "connect to roof" doesn't either.

Intersection between 2 and 3 is fine.

Intersection between 3 and 4 does not work because walls 2 and 4 are connecting, resulting in an undesired intersection line. Roof 3 should trim wall 4.

Any ideas on this one?

I would recommend having an SEO layer that is hidden in the end but on this layer you would have roof planes or other objects that cut the walls as desired. Sometimes it is much easier to perform SEO with operators that are not involved in the actual structure itself. This will look messy when everything is shown, but after you turn the layer off everything will look clean if done properly. Wall 2 &4: Create a new layer for Wall 4 and change the layer intersection number so that it will not interact with Wall 2.

This layer can be set to Wireframe mode in the Layers dialog box, so the elements on it are Wireframe in the 3D Window, and the finished model is easier to see.
