I've been given a structural IFC, containing two submodels in its model tree. the structural steelwork is in one model, and the trusses and framing are in another model within the same file. If I open the IFC in Solibri, I can see the elements of both models. see below scree...

We have a problem in our office that seems to occur any time we set up a new machine with archicad. I've seen it with AC27 and 28.We use a font, Century Gothic, as our office standard. This is not a standard macOS font and is installed via font book as part of the machine se...

What is the process for hotlinking an IFC4x3 model? I get an error message when I try. This is a huge problem for anyone working on large collaborative projects where the the BEP specifies IFC4x3 as the standard for file exchange.

In my situation right now, getting the structural engineer to give me two separate files is the way forward, and I have asked for this. In the situation in the thread that Cosmin linked to, where they have many more ifcBuildings in one IFC file, this isnt really a viable opt...

Hi Cosmin,Having all the hotlinked elements end up as morphs or objects is a long way from ideal. makes the file extremely heavy. Seems clear it's an issue with Archicad's IFC reader implementation that Graphisoft could easily resolve - but perhaps they aren't even aware it'...

Hi Laszlo, No, I am not using merge. I am hotlinking a structural IFC into the main design project file so that I can check wall thicknesses, clearances, etc. I do not wish to merge the IFC into my project file. File->External Content->Place hotlink. then select module. the ...
