IFCStructuralCurveMember axis component: how it works?
Hi there.
I'm trying to express the orientation of beam elements using the axis component of the IFCStructuralCurveMember entity:
But I've noticed that when importing [url=https://standards.buildingsmart.org/IFC ... member.htm]the example on the BuildingSmart site[\url], this component is ignored:
And if I try to set this component FreeCAD moves the corresponding beam. Could you help me to understand how it works?

I can not find a example ifc to test on this page.... But I've notices that when importing https://standards.buildingsmart.org/IFC ... member.htm the example on the BuildingSmart site, this component is ignored ...

Hi Bernd!
I'm asking about the Axis component of the IFC structural member object. I think it must contain the orientation of the beam element (so you know how the steel shape web -for example- is oriented in the space).

Ahh only the stupid shapes are imorted, none of the parametric smarteness of the arch component is used on import of structural members. This would need to be implemented before it would work.

Re: IFCStructuralCurveMember axis component: how it works?
You are correct. This has been implemented in the BlenderBIM Add-on by Jesusbill. How about a screenshare so we can share the progress done so far, and see if FreeCAD can perhaps copy some of the paradigms that we've been developing?l_pereztato wrote: ↑Sun May 16, 2021 9:07 am Hi Bernd!

The screenshot below shows the implementation. The user is presented with a single euler angle to manipulate it.

Re: IFCStructuralCurveMember axis component: how it works?
Thanks Moult!
I think I'll move my development under BlenderBIM and when it works there, I'll test it with FreeCAD.
Thanks again.

Cheers! I recommend contacting Jesusbill either on the OSArch chatroom or on the forums because he is the IFC structural guru!l_pereztato wrote: ↑Wed May 19, 2021 7:51 am Thanks Moult!

Re: IFCStructuralCurveMember axis component: how it works?
If you have a volume object in FreeCAD and set the structural axis for them it will use this axis for export to structural analysis ifc.
But what does not work ATM is on importing a structural analysis IFC the axis property will not be set.
@Moult:
Is it possible to export a structural analysis IFC from a volume modell? This is what is possible in FreeCAD and this is where the structural nodes (structural axis) can be moved without moveing the volume geometry.
