can archicad control wall heights to changing levels (revit)

Anonymous — Wed, 24 May 2023 11:05:56 GMT

I am also a very new convert to archicad.
But i have used revit for the last 3 years.
I wanted to know.
When i create two levels and make a wall.
can i attach this wall to the two levels, so later if the levels change, the walls will automatically follow?

Thanks.
Ian

In archicad you do this by setting a relationship between the wall and floors using Solid Element Operations (SEO). There are some tutorials on this that graphisoft posted on youtube.

In the 3D window select the wall and in the SEO settings box
click on the 'Get Target Elements' to set this as the 'target'.

Select the floors, and then set them as the 'operators by clicking on the 'Get Operator elements' button.

3. select 'Subtraction with downwards extrusion' for the operation. This will trim make the floors trim the wall that extends below the floor slab. If the floors will might be lowered, you can extend the bottom of the wall as the objects must overlap in space for the SEO to work.

4. Click the Execute button.

Unlike trimming with a roof which creates a fixed trim, this is a dynamic relationship. All elements must stay in the file for the trim to be in effect. In your situation the walls and floors are part of your model so they will stay in the file. If you wanted to use SEO to create a trim with an element that is not to be seen as part of your building, then you can create a layer for these SEO operators so they remain hidden but are still in the file.

At the risk of criticism, I must say that the answer is "No, you can't". The SEO method Erika mentions is nothing but a workaround and floor-to-floor-wall-height-option is something that has been long wished for; because in the end, while SEO might cut the extra parts of walls (or any other elements) and is a dynamic relationship, you still have manually adjust the wall's height so it overlaps and gets cut, and you have to keep an eye on floor display options as well.
The question is: if the wall-end tool can adapt to a wall height automatically, and you can get automatic floor-to-floor height coded in GDL using REQUEST, why can't there be a simple option in wall settings that says: WALL HEIGHT: manual / to next floor
Or am I missing something here?
Best regards.

On my ignorance about Archicad i would say that that feature doesn't exist in AC, and I hate. If I move the wall the atatched wall doesn't move with it, or if I change the story heights, all my walls are short.

Any workaround it appreciated.

In short , there is no identical option in ArchiCAD such the one that is in Revit.

the nearest you could have is the simple add-on _ story height_ :

IMHO, SEO will never replace the revit option simplicity (as explained by Since-V6)....not to mention the SEO in plan issue....

I hope that GS will give more serious solution to this request.

Fast, dirty, ugly, and simple proof its easy in GDL... please make it standard in wall settings.

place it in several floors and adjust floor height. should update. for ac13+, just be careful with home story setting for the object.

*EDIT*
removed attachment. scroll down to newer version

Archicad is not Revit. Using AC we create relationships when needed using SEO.

Indeed... archicad is not revit... I love it that way. But SEO will only get you that far. You still can't establish the other kind of relationships: the dimensional ones, where you need to keep an object to a certain distance of another one, or to keep it parallel, perpendicular, at a specific angle or constrained to the top level of a certain slab.

The fact that you need to model a wall with a 4m height for a 3m floor height and SEO away the top 1m just in case the floor height changes (and within that 1m one expects) is not really "BIM-correct", and is not really an intelligent relationship between parameters.

Best regards.

Has anyone used the new Trim to Roof/Shell element connection in AC15? I'm sure this same functionality could be added for slabs; however, it doesn't sound like it's much different than SEOs -- that is, it will trim but not extend attached walls.

In a non related answer, thanks for the simple add-on website, it's great!

You're welcome, there are indeed some interesting plugins there...

I had some free time and kept playing around with the previous fast, dirty, ugly, and simple object to see what came out and what other options could be available for walls.

I'll stop with this one here. I know it's not the GDL Forum or the Object Depository, but I still wanted to post it here since it is still related to floor-to-floor height, and the code is somewhat commented and could be useful to other people.

It´s a simple cube, with automatic height adjustment, with height options of manual, to next story, to top story, top bounding box and a specific story. These could be added to walls as well, of course with further study.

In its current state can be used as a 3D vertical shaft opening, that you can put in the bottom story, set its height to the top one, SEO from other slabs and forget about it. It'll self adjust to level changes.

If/when I develop it further (pens, materials, backgrounds, etc), I'll post it to the Depository.
Cheers everyone!!!

using the scroll ball of your mouse to pan

Hi There,

I'm new to archiCAD 14 (using MacBook Pro - Lion OS) so pardon my ignorance!

For some reason if I click down on the spin wheel of my mouse it won't allow me to grab and pan across the worksheet like I know it can, instead it goes to mission control - does someone know the magic trick to this?

I've fiddled with the mouse settings and mission control settings in system preferences and also just clicked the scroll ball in the ArchiCAD shortcut for pan but to no avail...

Thanks for you help!
Sarah

Odd that your post was added to this thread.

I do know that Graphisoft does not recommending using Lion yet -- that may have something to do with your problem.
