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.

Re: IFCStructuralCurveMember axis component: how it works?

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).

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: buildingsmart_ifcstructuralcurvemember_axis.png But I've noticed that when importing [url=https://standards.buildingsmart.org/IFC/RELEASE/IFC4_1/FINAL/HTML/annex/annex-e/...

Re: Implement IFCStructuralLoadLinearForce and IFCStructuralPlanarForce in the BIM module

Hi. I'm trying to get a better understanding about IFC load definition, and I'll return with my thoughts. Nevertheless, I think that the model must be as «FEM agnostic» as possible, namely, you define the geometry, the materials and the loads (the geometry and the values of the loads) and then it is...

Re: Implement IFCStructuralLoadLinearForce and IFCStructuralPlanarForce in the BIM module

Hi, Bernd! Thanks for your reply. Maybe I'm wrong, but I don't think that those attributes are intended to be used on the geometrical objects used to define the structural element. I think they must be used with the corresponding IfcStructuralSurfaceAction which can contain an IfcFaceSurface that de...

Implement IFCStructuralLoadLinearForce and IFCStructuralPlanarForce in the BIM module

Hi. I'm using the FreeCAD BIM module to create FEM models and import them to XC . I've no problems defining the model geometry, but when trying to define loads I've noticed that IFCStructuralLoadLinearForce and IFCStructuralPlanarForce are not implemented yet. Could you put me in the right direction...

Re: XC, opensource structural engineering FEM code

Well, thanks for your interest! Yeah we use Ubuntu but it must compile under Debian too. If not let me know and we'll fix that. About preprocessing: we have developed some meshing tools based on block topology (k-points, line, surface (quad), volume (cuboid)). For really complex meshes we use Salome...

Re: Structural IFC interface for XC.

Well, thank you very much!
I'll take a look to IfcOpenShell.

Thanks again!

Structural IFC interface for XC.

Hi. We are evaluating the possibility of developing an structural IFC interface for XC , using FreeCAD to translate from IFC to a Python file with the k-points, lines, surfaces, volumes used to generate the finite element mesh in XC. Is there a document that explains the document for newcomers (some...
