I am disappointed that C3D will not have a 64 bit version for the 2010 product.  This will give firms a year to upgrade their hardware to take full advantage of the future 64 bit version.  Civil 3D 2010 32 bit will benefit from running on a 64 bit machine now with more ram available you will see a great leap forward in stability and be closer fully realizing it’s dynamic modeling capabilities.

This post is a quick general Autocad tip as I recently discovered the built in SETBYLAYER command while looking for a LISP routine to change a selection set of entities color to ByLayer.

The SETBYLAYER command changes property and ByBlock settings for selected objects to ByLayer.

This command is a great cleanup tool if you have a drawing with a lot of entities that someone has set the color to a specific color rather than bylayer.
