@matthew85 Check the scale of your dwg import, it seems as if it is coming in smaller than what I imagine it should be. Revit doesn’t allow for rooms or spaces to be created in boundaries with a distance less than ~275mm.
As for obtaining the room name and number from your dwg, the only way to do that is to bring the dwg in with the text layer only and exploding it (this will create Revit text elements). You can then obtain these text elements and their values and push those into room parameters. This thread should help: Data attribution using information from a CAD file
