How to draw a BIM compatible Irregular shape- column, beam & lintel

Anonymous — Tue, 09 May 2023 13:48:47 GMT

Dear Archicad User
I am using ArchiCAD for the last 5 months to produce Architectural Construction Drawing. The experience was really good. The question arises when I am planning to send the model to a structural engineer. I need to be sure My model is good enough to integrate the structural model. What is the best practice to make this model BIM compatible? I mean, anyone using the BIM platform can use my model without any trouble.

I need to draw an irregular column, beam, and lintel. ( see attachment-1). Here is my method to do these?
1. For the column-
It has a capital on top ( see attachment-2).
I drew this using 2 columns( one top of another ).
2. For the Beam -
I used 3 beams ( see attachment-3).
3 For the Lintel or sunshade (for Door Window) -
I want to use a complex wall profile. ( see attachment-4).

I need to be sure these modeling methods are for irregular shapes is BIM compatible

Sincerely
Avi

In version 23, your beams and columns can all be one element with multiple segments.
Have a look a segmented beams and columns.

Like barry said, archicad 23 solves the problem,
But, i want to ask about something i didn't test it before, when exporting segmented beams and columns as IFC, to structural engeneer, and they are too comple, ( complex profiles with modifiers, custom surface overrides, etc... they export correctly to revit ? and when the engeneer finishes his work, do they come back correct like they are medeleed in the beginning ?

bouhmidage,

I think they should go through to Revit just fine because if you export geometries as BREP the geometry will be correct. Avishiplu, because of this, I would suggest that you model these Beams and Columns as multi-segment Beams/Columns and do not model them out of multiple elements. Then Revit person will see that the segments belong to the same element.

bouhmidage,

If I understand correctly you ask whether if you export multi-segment Beams/Columns as IFC, open them in Revit, then export the file from Revit as IFC and open that in Archicad, will those Beams/Columns come in as multi-segmented parametric elements?
The answer is no, and this should not be expected. File formats are so different that it is impossible to exchange geometry without data loss. This is the holy girl that will probably never happen.

The recommended workflow that works very well is to use IFC files received from others only as Reference Models and model everything that belongs to you in your own application. So if avishiplu exports his Beams and Columns as IFC, the Revit using engineer should import that, use it as a Reference, but still model the structural elements in Revit to create the structural model. Then he can export his structural model as IFC, which avishiplu can import into Archicad and use as a Reference Model.

Yes, your answer was about what i'm searching exactly,
So, IFC serves as a reference, and this seems to be logic, since structural engeneer won't model on archicad and calculate on revit, he would choose tekla for exemple,
And an Architect working on archicad which receives a strcutural model from frvit as IFC he will use it to check if there is some mistakes, or clashes, that's it ,
