[IfcViewer] Is there an IfcViewer that can show all the elements of the Structural analysis model?
Since IFC2x2 there is IfcStructuralAnalysisDomain. Here is the link to IFC4 documentation from IfcStructuralAnalysisDomain.
Is there an IfcViewer that shows not only the geometry, but also the loads and the results?
There is an example IFC file in the IFC4 documentation. I have tested this with the following IfcViewer:
BlenderBIM Version 230929
KITModelViewer Version 0.7
BIMcollab ZOOM Version 6.8
Structural BIM Viewer
xBlM Xplorer
Solibri Anywhere Version 9.12.10.20
FreeCAD NativeIFC
FreeCAD
So far I have only seen at least the geometry in the viewer, but no load or resulate. Does anyone know a viewer where you can see all elements from the IfcStructuralAnalysisDomain?

BlenderBIM shows and allows editing structural elements (plates, linear elements & fixity constraints), there also seems to be a tool for adding load-cases and loads. It doesn't look there is any tool for viewing results:
@brunopostle In the example IFC file it has the entity IfcStructuralCurveMember, this linerar structure was not displayed in BlenderBIM. But I see that IfcStructuralSurfaceMember is displayed as a two-dimensional structure in your scrennshot. Can you upload an IFC file with IfcStructuralSurfaceMember here in the forum so that I can confirm it myself in BlenderBIM? In the documentation of IFC4 there is unfortunately only one example concerning IfcStructuralAnalysisDomain. Are there more IFC examples from bSI somewhere else?
For me, the visualization of loads and results as shown in the IFC4 documentation is important. See the following pictures:
I don't want to create or change the loads in a GUI at the moment, but look at the loads, visually and the exact numbers.
More IfcViewer tested:
Autodesk Navisworks Manage 2020
Autodesk Construction Cloud
I'll try and upload a model later, this was created by the Homemaker add-on (which generates a structural analysis model with every IFC).
The structural analysis stuff has a dedicated BlenderBIM tab:
I am also keen to use BB for not only viewing but also editing structural analysis models.
I'm sure that in older versions of BB I was able to open the Analytical Model (line structural model, without loads). When I tried to open it in v230902 I can see just the vertices/nodes (without line structural elements:). Similar debate occurred in this thread from a year ago when the author explained that the coding was not completed. The code state seems to be unchanged since the attached thread?
Since I cannot help with code, I'd like to ask the authors @Jesusbill and @Moult to finish the "structural" code.
Regardless, thank you guys for the awesome work and tools.
PS: Having a tool like this for structural engineers will be awesome.
nice overview ... you should add this: https://ifcquery.com/ AFAIK the first one ever who even had shown structural geometry years ago. But AFAIK no results and no loads either, but conections, but no nice geometry inside the viewer for a connection.
years ago (really years ... ;-)) I collected a few ... with some information about this topic ... (but as said years ago) https://github.com/berndhahnebach/Ifc_StructuralAnalysisView. Thes examples are Ifc2x3 but AFAIK there has been nothing new in IFC4 in the regard of StructuralAnalysisView, or has there ?
Have you tried the KIT-Viewer https://www.iai.kit.edu/english/1302.php with the IfcTruss Plugin https://github.com/KIT-IAI/SDM_Plugin_IfcTruss ?
Have not tried it, but it looks like it can display the loads.
