We're finding that whenever we export a project to IFC, no matter what classifications, translators or mapping we use the site meshes never export. Has anyone else found this problem, and found a solution? We use the our of the box classifications & translators but always seem to have issues!
Much of the time everything also exports as IfcBuildingElementProxyType too, with no obvious logical reason (walls are classified as walls, etc but still come out wrong!) It's obviously something we're doing this end, but although sometimes we get it to work there never seems to be one solution!
Cheers
