Not able to get SEO to work correctly

[heathldesign]

Hello again,

i have a composite slab, and a complex wall sitting on it. i'm trying to get the SEO to get the wall to cut the carpet and underlayment of the slab. the wall materials are all stronger than the floor finishes, but whether i subtract or downward extrude the SEO i get the same result. and of course i can't merge a wall and slab.

I don't have the same composites and building materials as you, but there should be no need for SEO at all.

If the building materials are all correct, the strongest will cut the weakest automatically.

But also check that the skins for carpet and underlay are set as 'finish' or 'other' and not 'core'.

hi barry,

i checked the skins and they are finish. so i have no idea. i restarted and no change.

I don't think this is the problem, but who knows?

Go into Options > Project Preferences > Legacy and see if the box for legacy intersection is ticked (it shouldn't be).

Otherwise, maybe we can try something.

Select that wall and slab in plan, then save selection as a module.

Zip that MOD file and attach to reply here (can't attach MOD files directly).

I should then be able to open that MOD with all of your building materials.

Ensure the layers of your Complex Profile are also correctly asigned skin or core.

Is your floor not trimming the lower wall either? Looks like it is overlapping...
