Hi Angus,
Please see attached.
As in the pic (done in SKP), I want the outer surface/side of the slab to have 2 different finishing material/color (say yellow and white).
Is there a way ?
Please adivse.
Thanks

make two slabs, or very thin covering walls.

Hi all,
Thanks for input. Two-slab is what I thought of
But with one slab, can we do it ? Is there a way to split the surface ?

Please advise.
Many thanks

Hi all
With two-slab solution, is the joining lines (between slabs) on the floor plan visible ? If so, is there a way to hide it in the documentation drawings?
Please advise.
Many thanks

Why do you think your colleagues have suggested the two slab or wall veneer methods if there a magic way to do it otherwise?

make the slab edges white lines to hide them and if you dislike that, use the wall veneer method.

There's actually another method, but I don't really recommend it here. It may help in other situations.

When you do a solid element subtraction from something (the slab here), you can indicate that the subtracted faces get the material of the operator.

So, consider a slab into which you are cutting a hole for stairs. If the outside edge of the slab is brick for example (you are doing a crude core model without veneers for your walls) - and you cut a hole in the slab using the conventional method (slab selected, slab tool active, drag a rectangle to cut hole) - the edges of the hole will be brick.

But, if you want the edges of the hole to be white paint, you can subtract a big white paint slab from the first slab with 'use materials of operator'.

So, similarly - in this case - you can trim the edge of a slab with two different operators to apply two materials to the resulting edge.

Attached screenshot shows in foreground, two operators on the edge of an extended slab (resulting in the desired size) - one cube had white edges, the other had red. In the distance is the same sized slab with a normal hole (brick edges) and a hole cut via SEOp with a white slab - leaving white edges for the hole.

HTH,
Karl

seems that we have to use SEO as less as possible.

I use SEO very extensively with very few problems. The function is very mature now (I used to be more sparing in its use). The main problem that still persists is if you try to make recursive operations (like A operates on B and B operates on A) but this seems dangerous anyway and is easily avoided.

If you really hate those workaround... you can try this one.
Make a SEO subtraction, choosing the option to inherit the attributes from operators. Use two slabs with the two materials, allowing a very tiny overlapping (1mm) with your final slab.

Edit:
ooops.... seems I posted this too late.
Sorry

I wish we would not have to use the small overlap. Instead, AC would make it inherit even if they just touch and have that common edge.
