i have something to discuss abut the ifc-import to sketchup.
i am writig a ifc-viewer for sketchup and test a lot in different skp-versions.
so i came across the following problem:
i have a file, which i can import well in to sketchup 2021.
this file includes ifc-spaces, which are not filled with elements and they are at the same level as the ifc elements in the file
so you have imported:
…storey >> ifc_space
… storey >> ifc_window
or at two lowest ifc-levels
… storey >> ifc_curtain wall >> ifc-plate
here it is important to see, that there are 2 levels of ifc-elements unter ifc-storey at the lowest level of the ifc-path.
this can be imported in skp 2021 !!!
in 2023 this structure cannot be imported. sa soon, as you have nested elements in 2 levels unter the “ifc-storey”,
skp 2023 will not import.
here you get
… storey >> ifc_space >> instance
the instance has no classification, so the ifc-space is the deepest ifc-element.
that seems to be an import problem in skp 2023.
that in my opinion is the reason why some ifc-elements are not imported in 2023.
someone else with ideas or experience with this? i would be very interested, if somebody has another ideas to this problem.
