I would like to suggest the following for the IFC export using the "Export to IFC" function:

An option to automatically exclude all linear objects from the export. I want the IFC to only include 3D meshes, but right now it also exports linear elements. I need some of these linear elements as help lines for further use in modeling, but I do not want them to be exported to IFC.

Alternatively, a way to automatically set the linear elements created from corridors on the "default" layer to the element class "construction", since the export of construction classes is disabled in the mapping file.
