BlenderBIM, Is a wall in a ifc-file based on a wire or based on a face or just a bound of faces

edited September 13 in General

I assume this can be found in BlenderBIM, but how?

If it is based on a wire. Where can the wall thickness be found and changed?

a sample ifc file is attached ...

cheers bernd

    Hello Bernd, Just guessing ti see if i can understand something :)
    Wall on line 62 for example has 2 representation. One Is the body and One Is the axis.
    The body Is an extrudedareasolid, based on a rectangle that has a thickness of 0.15m. so if you want to change the thickness you should change that parameter at line 49.
    The axis Is a 2 point polyline, defined at row 57, and has anything to do with the definition of the body representation and so with the thickness.
    I dont see in the file any informations about the material, so the thickness of the Wall seems only to be represented in the Wall body...

    Hope i didn't write any wrong thing :)

    This is what I know from all my ifc knowledge too. :-)

    But I am interested to know how this information could be retrieved and changed in BlenderBIM gui?

  • The IFC material Type of the IFC wall gives it it's thickness, you can change it from there

  • where do I find this in Blender BIM? Do you have a screen?


  • Here is a screenshot ^

  • And here is a video showing how IFC Object materials are created in BlenderBim:

    You can also just load from the IFC library that is available and just edit the wall materials found there
    The attached file is just my naming scheme you can download the latest libraries here:

    Which version of BlenderBIM is that?

  • I'm running 12.09.2021

    Normally I'm on the daily build,
    but this featureset has been there since 22.05.2021

  • You can find the latest build here:
    https://github.com/IfcOpenShell/IfcOpenShell/releases
    download the py39 version of whatever OS you use
