I have just downloaded the "Bridge Modeler" extension to Civil 3D, but the instructions are rather lacking. I did a quick search on Civil 3D blogs, and when BM was in labs.autodesk.com, there was a PDF called "Getting Started Guide Bridge Modeler for Autocad 2011".
Did a Google search, Bing - any and all search engines, and no luck finding it, other that in grainy individual pictures. Anyone out there care to share the PDF with me?
