[BlenderBIM] How to create a simple StructuralAnalysisModel?

1. S by smr02 on 4 Oct 2022, edited 24 Mar 2023 #

   Hello,

   I'm new to blenderBIM and i want to create a simple Structural analysis model. For example a frame structure with a line loading, supports and maybe a hinge.

   I would be very thankful for some guideline on how to start.

   Would this file help you get started?

   @Jesusbill might have some more insight, as well.

   @theoryshaw thank you! That was helpful.

   I've managed to create Beams, hinges/connections and supports. However, how do I add a load e.g. on a beam?

   This might help too...

   https://sourcegraph.com/search?q=context:global+IfcStructuralLoadGroup+file:%5C.ifc%24&patternType=standard

   just replace what is circled below, with an ifc entity you're curious about, to find examples of IFC files out in the wild.

   Also, here's an exhaustive list of all the IFC entities, for your viewing pleasure. :)

   Found this.

    Hi @smr02 at the moment it is not possible to assign loads, load cases and load combinations; the development was done up to the model definition point (create model + elements + connections) with Dion, then some initial work on creating loads and load assignment was done but it was not completed (thus the "ghost" icons in the screenshot of @theoryshaw :D) and this was more than a year ago and before the refactoring of BBIM. Unfortunately I haven't got the time until now to work or further support this process, but the will to conclude it is definitely there.

    The good news is that from this month I can start allocating some time on this, so hopefully we can bring it forward and conclude load, load cases and load case combination assignments.

    PS: Thanks @theoryshaw for the shoutout

    Hi @Jesusbill, I am also very interested in creating a StructuralAnalysisModel using Blender BIM. Is it possible to assign loads now? I also have another question. How to assign IFCStructuralCurveMember to IFCBeam (something like IfcRelAssignsToProduct) in Blender BIM? Thank you for your help!
