I have a max model object (fbx) and primitive objects of unity. A user can see it in a drive unit. Now I want to offer end users a feature allowing them to export the unit game object to the IFC file format. Since I mainly have objects related to architecture (such as building, floor or wall, etc.), these objects must be exportable to the IFC file format, Industry Foundation Classes IFC file format. ), managed by buildingSMART®.
