What type of application are you doing? AutoCAD .NET API plugin (the topic of this forum)? or an EXE app that automate AutoCAD via its COM API (because you use AutoCAD COM API here)? If it is former, then why do you need to use ObjectDBX's AxDbDocument?
AxDbDocument object cannot be "new"ed. You create an instance of it via an AcadApplication (e.g. a running AutoCAD session), calling its GetInterfaceObject() method. So, you have to post your code showing how/where you have/can obtain an AcadApplication object before you can use it to get an AxDbDocument.
When post your code. make sure you use "</>" button in the toolbar of the message window.
