I found this link today. There is some information in the video (about 35 minutes into part1) with a couple of demonstrations as well as documents under "Autodesk Architecture, Engineering, Construction & Geospatial 2010 Launch Press materials."
Things I like:
View in Context clash results
Grouping multiple clashes as a result of one issue
What I wanted to see (maybe it will still be there):
HTML Clash report customization interface (instead of editing xsl files)
What I didn't want to see:
Steering Wheel/View cube...they just get in my way.
I'd like to find out more about the new section box and align section tools, sadly there was no information about them in the webcast.
Thoughts everyone? Have you seen this information? What were you wanting to see vs. what they are promising?
