title: Where is the documentation for Autodesk.AutoCAD.Interop?
body: <p>I've looked in the ObjectARX SDK, in AutoCAD Help, on the Autodesk Developer Network, in SO and the broader internet, but I can't find documentation for the Autodesk.AutoCAD.Interop dll, only documentation for the in-process .NET API.</p>
  
  <p>For example, there's plenty of info about the Application object:</p>
  
  <p><a href="http://docs.autodesk.com/ACD/2013/ENU/index.html?url=files/GUID-4E1AAFA9-740E-4097-800C-CAED09CDFF12.htm,topicNumber=d30e712496" rel="nofollow noreferrer">http://docs.autodesk.com/ACD/2013/ENU/index.html?url=files/GUID-4E1AAFA9-740E-4097-800C-CAED09CDFF12.htm,topicNumber=d30e712496</a></p>
  
  <p>...but no similar information about the AcadApplication object exposed by Autodesk.AutoCAD.Interop. Where can I find detailed information about the interop API?</p>
  
  <p>There are some examples of using it to start AutoCAD:</p>

  <p>...etc. But I'm looking for object graphs, method descriptions, etc. for the interop API, i.e., the kind of information available for the in-process .NET API.</p>
