My friend and Vectorworks teacher, Jonathan Pickup, recently turned me onto a Vectorworks 3rd party plug-in that is fantastic!
Jon sent me his manual and I downloaded Camera Match from Matt Panzer in San Francisco. The tool allows you to insert models accurately into photos.
This is especially useful for me to demonstrate what a building will look like in its future site. I found the tool to be very easy to use, and by following Jon's
manual produced my first example in about 10 minutes - and here it is.....
This is the fishing cabin I previously wrote about sitting on the future site of the frame that I just blogged about.

I can see myself using this tool extensively for not only presentation drawings, but also to use in designing renovations and additions.
Here is Jon's youtube video that does a nice job of demonstrating camera match: http://www.youtube.com/watch?v=3229qXnJ9-8
