Hello everyone,   I am wondering if it is possible to export multiple site models within the same drawing into a single IFC file.  As you can see below, I have modelled a project in several areas each as their own model.  The best result I have had so far is just getting one site alone with the constructed elements.  Perhaps there is another solution or workflow? (will be trying from mesh surfaces next)   Much thanks for any tips, and the file is attached. Test2.vwx
