Slab to Terrain

[Anonymous]

Hi all,

Firstly, apologies if this is in the wrong section. I am trying to find a way to bring the slab down to the terrain level, so that there isn't a gap (as shown in the attached screenshot). The other side of the slab is cut out of the terrain, but as the land slopes away it creates a gap.

Hope that makes sense.
Cheers.

To move the slab down is easy - just change its 'offset to home storey' value in the slab settings or just drag it vertically in 3D or elevation.
However you will also need to adjust the height of all your walls, roofs, objects, etc.

It will be much easier to adjust the height of the mesh in the settings (bottom offset to home storey) or just drag it in 3D or elevation which is easier because you can see it visually).

You will now have to cut more out of the mesh on the other side - or you could add another mesh or modify this one so you can fill the gap rather than digging the whole building in deeper.

Thanks. I'll probably just adjust the height of the mesh I'd say, which I had done previously.

Surely there has to be an easier way to move soil, terrain, etc. when you're doing a cut/fill on a site.

If you are happy with the surface levels on the mesh but just want to move it relative to the building model then that is what you do - just move the entire mesh.

But if you are wanting to adjust cut and fill levels then you can adjust the 'Z' height of individual nodes on the surface of the mesh - either by dragging or setting actual values.
You may need to add extra nodes to the mesh so you can adjust them as you want.
I draw 2D splines for where I want the cut/fill extents and then 'Magic Wand' these into the mesh to create the contours and nodes in the mesh surface that can be adjusted.

I am sure there used to be movies in the Archicad YouTube channel (HELP menu) that explained meshes a bit.
It is much easier to see it rather than explain it.

Barry.
