You should be changing things using the Edit Selection Set command.<BR /> <BR /> This will only let you later create a 2D GDL object. To create 3D GDL from a dwg, you must open the dwg as an object.<BR /> <BR /> Cheers,.<BR /> Karl Thu, 30 Apr 2009 03:54:11 GMT https://community.graphisoft.com/t5/Project-data-BIM/Merging-DWG-to-create-a-GDL/m-p/126361#M7833 Karl Ottenstein 2009-04-30T03:54:11Z https://community.graphisoft.com/t5/Project-data-BIM/Merging-DWG-to-create-a-GDL/m-p/126362#M7834 It is also possible that the layer that SOME items are on is LOCKED... your first step might be to UNLOCK ALL LAYERS.<BR /> <BR /> <BR /> Guessing again...
