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...

Since older topics seem to have been locked, I cannot expand the already existing topic... https://community.graphisoft.com/t5/Project-data-BIM/Schedule-the-U-Value-of-an-element-from-Energy-Model/m-p/323131#M3918 Is it possible in some way to schedu...

As some of you may know, Ruben Van de Walle @Ruben V and myself wrote a book on Archicad for Packt publishing. It's about 600 pages and takes you from start to a level where you should feel confident in setting up a project, make the model, and prepa...

With IFC export, the translator provides the option to split elements into parts. I'm trying to export a door with its parts, but it remains a single object upon export. Does this setting also require a specific setup of the GDL code to distinguish b...

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.

IFC2x3 Coordination View 2.0 is still widely used. And it has some support for extrusions upon export, but every time you have geometry that is not a strict extruded shape, it will become BREP. This is try for Archicad IFC export and for Revit IFC ex...

Layers = a single tag (each element can sit on only one layer) which controls visibility and a few other aspects (locking/freezing) Revit formally lacks layers, but has means to manage this with Filters & Worksets Layers is recognisable for CAD users...

I'm old enough to still remember 3-year release cycles of BIM and CAD software. And frankly, I preferred it this way. While I don't necessarily object to new and shiny features, stability and compatibility may be jeopardised this way. With a new rele...
