If you watch the Autodesk Civil 3d Webcasts on Friday, have you wanted to re-see or have the Powerpoints that they use. You can download PDF versions of them while you are watching.
Let me explain. During the Webcast if you enter "Ctrl+P" or select the "File" pulldown in the "Live Meeting" screen then select "Print to PDF", a PDF file of the Powerpoint will load on your machine. You can then either print or save it to a file.
This allows you to revisit much of the important content from the session.
