v4

Configuring something as Bulk now also works for FBX (if imported into dProB v2025.1.5-rc2 or later).
This requires Custom Properties to be enabled in the FBX export dialog, so the Plugin now automatically registers an FBX export operator preset for FBX export to dProB.

The Plugin can now be installed without Bonsai (though every IFC-related feature only works if it is installed).

v3

New feature: dProB Rail Spline Asset export

V2.1 - Migration for Bonsai

Updates the imports to deal with the renaming of BlenderBIM to Bonsai

v2

More Tools, mainly for cleaning IFC Files.

New Feature: Clean and Reduce IFC

• per Default only removes non-relevant vertex data (all models should look exectely the same!)
• Option: Decimate. Per Default at "1.0", so preserves all mesh detail. Lower values reduce the mesh complexity. [Currently experimental, as the results are still meh. Default of 1 should be good for most cases]

Results:

• (Massiv) Reduction of vertices - tested between 25-60%
• Sometimes smaller IFC File-Sizes, but not always. Might sometimes even increase file size, model should still be way easier to use.

Further Improvements / Tipps:
Upgrade to IFC4 using Blenders tooling. This will further improve IFC File size and therefore loading / saving etc.
Might also be added in a future version of this system!
