Working with BIM file
When working with BIM files it is recommended to separate the different parts of the scene into more modular pieces.
In general, we suggest separating the building "structure" from the building "assets". Structure would refer to slabs, floors, ceilings, walls, doors, windows etc. While assets would refer to the HVAC, plumbing, furniture etc.
When dealing with multi-storey structures, we recommend that each storey gets exported individually.
Example IFC hierarchy:
In this example, assume we have a basic IFC file with the above structure and only concerned with the first storey.
Modularising this would result in 3 glb files:
Contents of Storey_0.glb:
Storey_0.glb will only contain the structure of that storey. We do not include annotations or furniture.
Contents of Chair_0.glb
Contents of Table_0.glb
For repeating furniture, we only need to export one of each type.
Once we've planned how the scene is going to be modularised, the next step is to actually export it as a .glb file.
In this section we will explore how to export a glb file using Blender from an IFC file.
- 1.Export BIM file as IFC file
- 3.Import IFC file into Blender
- 4.Select objects to export with modularisation in mind.
- 5.Go to
- 6.Browse to directory to save
- 7.On the right panel of the export window
- 1.Twirl down
Limit to Selected Objects
- 8.Name the file
