Graph viewer of IFC structure in Bonsai: Interested? Features?

JakobJakob
in General

Hi Community,

I am updating my suite of educational tools to teach uni students about open BIM concepts,
Among them I have created
https://github.com/jakob-beetz/ifcopenshell-notebooks
https://github.com/jakob-beetz/IfcOpenShellScriptingTutorial/
and other stuff over the years.
As I had used have been using Blender(BIM) in education for a long time and am thinking of rolling all of this into Bonsai.

Such a graph viewer comes in handy to understand and debug models, get insights etc.
I am not sure how interesting this might be to you.
If it is, I will clean the code, add some features and put it in a separate repo (it creates additional dependencies, and I'd rather not pollute Bonsai with a PR with it...)
Things on my agenda:

  • Interaction (click on a node, get the selection in Blender)
  • All attributes and on the node labels
  • auto-focus
  • UI elements for graph recursion depth, ENTITY blacklists etc.

Any thoughts?
Thanks for any comments and suggestions

Jakob

    I still consider myself a novice with IFC, so such a tool would be great!

    This is a good visualization of the fact that IFC is an entity relationship model.
    I have used this software to visualize IFC files. Since it is open source, I will introduce it to you. Please translate as it is in Japanese.

    This tool as another tab in the WebUI? How about it?

    Hi guys thanks for the feedback!

    Here is a first draft. Let me know if this works for you. Not sure about the installation on other platforms http://graphviz.org must be installed on your platform.

    fantastic!

    @Jakob I just give your graph tool a try - really nice.
    I had to tweak the code for an IFC4x3 model, otherwise, no issues at all. Super cool feature.
    Thanks

    Hi @Rick_Brice , thanks a lot for the feedback!
    I'd be very happy to learn more about and incorporate your IFC4x3 tweaks. I have a few (cosmetic) updates and could add your modifications. Pull Request or some snippets here ... whatever works best for you. I also had a brief conversation with @dionmoult discussing some options to add this to the debug panel in bonsai itself and/or createing a WebUI panel with some nicer SVG rendering, interactivity etc. as @walpa suggested.

    @Jakob all i did was change the hard coded IFC4 to IFC4X3 in init.py
    I think the ‘ifcopenshell.file.schema’ property gives the schema of the open file so maybe this works instead of hard coding. I haven’t tried it yet.
