While learning the 2010 product one of the simplest improvements is one that got me the most excited, especially from a troubleshooting standpoint. This can be very useful not only to us in Product Support, but to our Resellers providing support and also end users reviewing clients drawings. You ever get a drawing with a corridor from a customer that has 10 different baselines and 25 different regions? Needless to say you could spend a bit of time trying to find that one specific region that your customer or client had a question about. In Civil 3D 2010 they made this process a whole lot easier. In the Corridor Properties dialog box you now can select the region, right click, ZOOM TO, and there you are. Finding those Corridor Regions has never been easier!
