Hello, I am looking for some help with changing a property set def in ADT2004/2005. This is where I'm at, but I don't see the specific entry for the RoomObjects dictionary, or where to get/change any of it's properties. (vlax-dump-object (vla-get-Dictionaries (vla-get-ActiveDocument (vlax-get-acad-object)))) Specifically, inside RoomObjects I'm looking to change Data Type : Auto Increment - Integer to Data Type : Auto Increment - Character Any help would be greatly appreciated. Thank you.
