Hi
I'm trying to export a DGN to IFC with some modifications to the elements colours. I found this thread on the subject:https://communities.bentley.com/products/building/building_analysis___design/f/aecosim-speedikon-forum/217732/maintaining-materials-colours-when-exporting-dgn-to-ifc/667233#667233
Alifur Mandal says that "Till now, if we export a dgn file to IFC, only wireframe colors will be visible in the IFC. None of the material color will be visible in the IFC. If in DGN file, in the wireframe mode it is red, the IFC material color will be red, if it would be green in dgn wireframe then it will be green in the IFC file"
In my DGN i have level override on and set to display certain levels to red:
But they are exported as green anyway (The levels original colour):
So, is there any other way to change the colour of an IFC-element without changing the levels colour?

Hello Robert,
The community thread you are referring is an older thread when there was no support for material color to export to IFC so by default takes the color from Parts. Now after Update 9, OBD is able to export material colors to IFC. Please see the below image. The textures are not being exported to IFC yet.

Ok, so that is solved.
Although, I just wanted to export to IFC with my level override colours, or change the colors some other way. As the case was in the other tread, I'm not after the material colour. I only saw your comment that IFC is exported as it looks like in wireframe, but I didn't get that to work.
So, is there another way to change the colours?
As you can see in the below image, if you use OBD update 9 then a wall & window assembly would look something like this, which is easily distinguishable. Also if the material of the window is glass then it would have transparency too.
I hope this is what you want as an outcome.
Also, I wasn't able to export IFC with the material either, is there any configuration variables I need to set, or anything else I have to do?
In my experience it also depends on the type of IFC export. I once made a comparison of the same model exported as IFC2x3 CV2.0, IFC4 RV and IFC4 DTV (from left to right in the picture below). As you'll see the colours are not always exported in the same way. This was done in U9 when it just came out:

No, not really. The projects BIM-manager wanted different colours depending on type of builing-elements (beams, columns, wall).
