I think it's cool that a national authority also issues IFCs!

Since part of the Matterhorn is on the Italian territory, maybe part of a Matterhorn in IFC? ?

I asked on Swisstopo for the ifc data regarding area around Matterhorn. Data in dxf for buildings and surface can be downloaded for free. If we would like to have the data in ifc we would have to pay 64 CHF which is around 64 Euro.

Actually the buildings are also available for free in 3D shapefile. So it's quite easy to bring them with the terrain through BlenderGIS

I tested the example with https://validate.buildingsmart.org/ and there was a problem with IfcPerson.
I also found it a pity that IfcProjectedCRS was not used, instead this information was in a separate txt file.
I have written both points to swisstopo by e-mail.
