Hi. I was wondering if someone could help me figure out how to view the separate composite materials in the 3D window please. I've seen other examples where it is done, but all my composite walls are shown as different shades of grey. I have checked the 'Use Element Attributes' checkbox under Cut Surface Display in the 'Filter and Cut Elements in 3D' dialogue box but that hasn't helped.

I am using Archicad 20 on a Windows computer.

Go to: Options > Project Preferences > Legacy

And review that "Use legacy intersection and Surface methods for model" is OFF.
Unchecking this, will use Building Material intersection priority for skins - so you're model and intersections will likely change as a result. Also, skins will be visible in the model.

It's good to review the Help here: ... rinciples/

(from this page onwards).

Also, what is telling the floor slabs and the ceiling to look like timber (This is not their material property) and the footing to look like brickwork? That seems to be the setting I need to find..
Now you need to set the correct building materials for your elements.
And for those elements made with a composite or complex profile (i.e. wall or slab) you will need to set the correct building materials in those composites or in the profile editor.

For your external surfaces you either need to override with the surface material you want or turn the override off and let it use the building material.

Thanks Barry. I had the correct materials set up but all the building materials were set to the surface 'General' which was making them not view. Now I know! Thanks for your help.
