We have an FEM of a bridge and would like to convert this in some way to a BIM. Preferably using some OS solution with an open data format. I'd be very happy to use the (still) experimental IFC4.3 / IFC Bridge as open data format in combination with the BlenderBIM add-on, but I don't think that is possible yet, as IfcOpenShell only supports IFC2x3 & IFC4.
Is there somebody that is working / worked on something similar or wishes to do the same? Maybe somebody has suggestions on what software to use? I don't think anything supports IFC4.3 yet does it? I was also thinking using CityJSON with a self-made bridge extension, based on the CityGML Bridge ADE. Wouldn't exactly qualify as BIM, but would be fit for the purpose of providing a range of end users (with and without expertise) information. And would make for a nice research :)
