Accessing Civil 3D with AutoLisp

[abain.117305]

We're using Civil 3D to design storm sewer pipe networks (pipes and manholes or inlets).

I want to use AutoLisp to access the pipe network data to generate some special reports that Civil 3D doesn't provide. However, I can't figure out how to access the network data.

Can anyone give me some direction?

Very basic... for 2010, and no error checking included....

(vla-GetInterfaceObject 
   (vlax-get-acad-object) 
   "AeccXUiPipe.AeccPipeApplication.7.0"
)
