There is a 2019 post with a similar subject, but I'm looking for a more general solution. I'm setting up modelling conventions based on IFC and need to confirm if this also works inside Archicad. Base Quantities for beams, columns and quite a few oth...

When you import an IDS file, every property/property set as specified in the IDS, will be included to get imported. However, this way, your Archicad model gets a bunch of Pset_WallCommon and Pset_DoorCommon etc... with no distinction based on classif...

Today I tried the buildingSMART validation service with an Archicad IFC exported file (from Archicad 27, but I don't think it's version specific). And one of the errors I receive is about the strict requirement of any Length to be positive (greater o...

With the current ISO publication of ISO 16739-1:2024 (aka IFC4.3) it would be good to gradually refine the mappings we can perform. E.g. I was looking at wall Coping and found that this now exists in the PredefinedType enumeration of IfcCovering sinc...

We’re trying to use IfcSpatialZone to model compartments. Alas, I don’t find a way to do this with Archicad. I’ve seen threads in this forum from 2020 asking for it. I guess this wasn’t a requirement to get IFC4 certified?

BIMdata.io webviewer has control over Layer visibility Catenda Hub as well (a little less intuitive - "hide" in the layer tree, no check-boxes).

Your question is unclear. What do you mean with a catalog? Just a series of objects put side by side in Archicad? Any IFC-viewer will highlight the object if you select it in the tree panel. And most of them also do the reverse: pick an object in the...

IMHO, the recommended approach is use a separate classification system for Elements (function) and another for e.g. materials. E.g., use the main Archicad classification mainly for functional description (and mapping to IFC schema) and use a separate...

That tip has quite a cumbersome workaround. You can simply filter out the "Beam Segment" and "Column Segment" and similar using the Element Type as a filter in your schedule criteria.
