Slabs and floor plan cut plane

[Nik]

How do you stop slab elements that are above the floor plan cut plane from appearing on plan views? For example we have window reveals and other elements that are very high up (way above the cut plane), but are still appearing on the plan view despite setting the cut plane and range. Any thoughts?

Cheers, Nik

Very good suggestion. 

A staggered cut plane would solve a lot of things, but probably not quite rhis one.

The proper solution would be to be able to look up from cut plane.

However @mthd , do not be shy to wish for the staggered cut plane. That vould be highly valuable in split level car parks, atrium and all similar situations. 

When it comes to slabs plan representation, cut planes atm are not connected to slabs...

Connecting cut planes to slabs would also go a long way.

Hi @Karoly Horvath, yes it would certainly need someone who works on multi story buildings to make a wish like this. The ability to look up +ve or down -ve with various projection settings and even to set the line styles in the dialogue could help our cause.

Yeah, the most interesting fact is that the capability to show the model "as it is" from above already exists (using a 3d view with ortographic projection). Combining it with the simbolic view to "see" things as proyections above the cut plane shoulndt be THAT difficult.   

We already do this with some layout work anyway,  but it would be nice if Archicad showed the model based on industry standards for say 95% of cases AUTOMATICALLY, the other 5% being special cases or complicated projects that may need a little bit more fine tunning.

Thats right, but to make the most of it, having the ability to generate more reference leveles WITHOUT generating a floor plan would be nice.   It would allow to handle all split levels situations with ease.

Potentially a horizontal staggered cut plane tool that works like a section could solve not only this problem above but also for “Split Levels” as you say. It may also be useful for “Reflected Ceiling Plan” views, particularly if you can get it to look up as well as down. Kill three birds with one stone.

The coding is already there for staggered cross sections so you would take that patch out and modify it to cut or slice through the building horizontally.

It might just be “the best thing since sliced bread” or the best thing since horizontal sliced buildings 😆.

Version 30 wish maybe ?

@mthd 

Please put it through as a wixh!

[Karoly Horvath]

Very true!

Hi all, I found this official training video on the workflow for creating a reflected ceiling plan. It’s with the older interface of Archicad and it might actually help with the initial problem above hopefully ?

@Nik 

The solution is a combination of the window and wall settings. 

You can set the window to show as projected, but if you set the wall to cut only, it surely won't show the windows that are above the cutting plane.

This is exactly what does not work. 

I said it earlier, if someone suggests to to the ceiling plans as a 3 Ddocument, I will cry.

Now im crying.

- the ceiling will be correctly represented, but you can't show door swings.

- the view is completely static. You can't edit anything. This means documenting and modeling is totally separated.

- You have to work in the normal plan view and 3D views to get the geometry you need, then go to the 3D Doc ceiling plan to label and dimension things...

I still remember Archicad 4.5. There everything worked this way, but that was OK, since other tools couldn't even generate a decent 3D.

But it is absolutely not ok in 2025.
