Hello all,
I am currently modeling a historical window for testing purposes. How do I get a 1:1 result (or LOD 200) from the laser scan? is there a Grasshopper file for this? Theoretically I could model a 2D/3D block… But then it is not a real BIM window when I export it as IFC 2x3.

Solved in a first step. There are certainly other and better ways. Everything generated in window mode and partially 3D modeled + IFC classified. If someone of you has a .gh file, I take very gladly…
Hi @Boris_87,
You can tag a block with an IFC type, so that it will be recognised as a BIM object when you export it.
You can also create a window from a block: https://www.visualarq.com/support/tip/how-can-i-create-customized-doors-or-windows/
Hello Alfonso
Thank you very much for your help.
Theoretically, yes. But it is not defined what the parts are. Window frames, glass, etc… Even already windows designed with the window style wizard, ArchiCAD for example does not recognise that it is glass. As you also mentioned, this probably has to do with the IFC2x3 coding. Or is there a solution for this? I have also contacted ArchiCAD support. Theoretically you would only have to extend the IFC import with the programming of VisualARQ or .val or a direct .3dm import with addition. Then the Boolean connections would have been solved without errors, etc. Also the IFC-ID trunk would be much more accurate + classifications.
Many greetings
Boris

Hello @Boris_87,
Yes, if you create a window from a block frames, glass, etc. will not be defined.
This information is being exported from VisualARQ to IFC, but I am not sure if ArchiCAD is importing it.
There is a plug-in to connect Rhino with ArchiCAD from Grasshopper, so you could use it to take VisualARQ objects to ArchiCAD (similarly as done with Rhino.inside.Revit): https://www.food4rhino.com/en/app/rhinoceros-archicad-connection
Hello Alfonso
Thank you for your help
I would very much like to use the plugin from Grasshopper… But unfortunately I have almost (still) no knowledge about Grasshoppers! That’s why I’m always very happy when I can download a .gh file. It’s actually about an import .gh file for Revit and ArchiCAD 
Many greetings
Boris
