Door threshold credibility gap

[Anonymous]

Let me first explain how this project is set up;

Finished floor level is set at '0'. Slabs of 15mm thickness are used to create various floor coverings such as wood, carpet etc. In 2D 'cover fills' generate our floor finishes drawing, and in 3D we get an accurate visual representation of floor finishes from room to room using this method.
Another slab is used for an entire floor area to indicate a structural slab in section. The top of the structural slab is set at -15mm.
The walls are set at -15mm up to ceiling height. This however means that when you place a door, I get this problem of not being able to 'see' my floor coverings meeting in the doorway. Why?
Lifting the door up to +15mm means I can see wall. Am I meant to be using this combination of elements in a different way to eliminate this problem?

This is in AC18. Thanks in advance.

I don't have access to my AC just now. Just a thought can you modify the threshold element of the door component and match your finishes? It may require the door opening size to be increased, which could affect schedules. Can be a catch-22 some of these problems.

Other option if door dimensions are critical would be to create a threshold slab and SEO subtract it from the wall.

dan_g:

I cannot tell from your screen shots: does the floor coverings Slab go into the door opening, under the Wall, or stop at the face of Wall. Also check the Building Material's Intersection Priority of the Wall and floor coverings Slab, the Wall may be cutting the Slab.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

Try to increase the Intersection Priority number of the Building Material of the Floor Covering Slab so it is stronger than that of the Wall. Right now Wall skins are stronger than that at the threshold, this is why you see that and not the Slab.

Why do you use 2 slabs (one for finish and another one for structure)?
Is there a problem with composites?

[alemanda]

I always model my building as dan_g did.
I think it is the more correct way to do BIM, at least when you have to manage all the disciplines (structures, block works, finishings, etc). So we model our project according the way it is built.
So we model a slab for structural purpose, and slabs for floor finishings. The same for block works and wall finishings.
Usually we model the thresholds. In fact We put the door at 10cm above the structural slab and increase the hole of the door downward so that we need to model the threshold. This helps us also for quantity take off. We don't use the thresholds included in the doors

It's true that you should model the way it's built, but there is no reason why you shouldn't use the composites. Two slabs on top of each other must be a pita to model / modify / update. The same with wall finishings. How do you insert a window or a door in multiple walls?

Why not have the Structural slab at 0 elevation, with the base of walls at 0, and thin finishes slabs above that? Undercut doors by 20mm and take finishes into openings, as it would be done in reality.

Reality is usually much more complicated than composites possibilities.

Multiple walls = multiple doors. For example when we model stone cladding we insert a door in the block work and an empty door(I mean just the hole)in the cladding (which isusually done with a double wall parallel to the main block work wall)

In this way we can control the model in a perfect way. Of course we have an addintional amount of work. But usually we do this when we have to produce construction drawings.
