SketchUp IFC Manager extension

Hi Everyone!

For the past year I have been working on a new version of my IFC Manager extension.
The first versions were very much focused on the dutch specific way of working with IFC surrounding the “BIM Basic IDM” and it’s dutch matching “NL-SfB” classification system (implemented as a native SketchUp classification!).

The main goal of this extension is to quickly setup an IFC model structure and create a better mapping of SketchUp properties (like classifications and IFC attributes) to IFC than is done with the current native exporter.

I took a stab at internationalising it after Malte Palmen contributed the German “DIN 276-1” classification system.
Now it’s possible to add more classification systems, so if anyone is using “uniformat” or “Omniclass” or “ETIM”… Let me know if you need some help adding those.

Information about the BIM Basic IDM:

Before I try to get the plugin into the extension warehouse I would like to do some more testing, especially in using the new dialog. Are there people interested in helping me out with that?



New version 3.2.0 adds common PropertySets when applying IFC types.
For example when labeling a component as “IfcWall”, the official propertyset “PSet_WallCommon” is added.
This gives the possibility to set parameters like “IsExternal” and “LoadBearing”


Another update, version 3.3.0, the last one for 2020! :grin:

  • Big improvement in exporting of properties
  • Added site to context menu

New release containing a lot of clean up and some improvements in performance. Also fixed a bug that got into the DIN 276-1 classification export.

Also included the improved NL-SfB classification by @MikeWayzovski!


Ok, new release that I consider the definitive 3.x version!
Should be pretty stable by now. If you do find any issues, please let me know.


and 3.5.0


Note: Currently this is a “Pre-Release” and not yet a “stable” version.


Hi brewsky I am interested in using Omniclass in my SketchUp files. Can you tell me if I can use your plugin to do it?

Technically it should be pretty simple, but the license for those kind of classification systems (uniformat,omniclass etc) has been keeping me from including them because it’s not clear to me of it’s allowed to redistribute those lists (in another form like the Sketchup skc/xsd)

OmniClass_EULA.PDF (37.2 KB)

Here is some information about the licenses. As I understand it the lists can be distributed without modification.

To be able to load the list into sketchup it must be converted into a SKC file, and I believe that is prohibited due to the fact that it would be a “derivative work”.

But it would be great to have that! Might be interesting to check if the “NBIMS-US” guys could create an official SKC.
