Often i have to create dwg's of a drawing composed of specific layers which in many cases is already set up in my sheets. Now to have to go turning on all the necessary layers again to export to DWG-on layers is a pain. Cmon guys this is an easy one to build into the next version.
You can do this in v11 by using the File/Purge/Save As DWG...
You can use GTV's, MSP sheets, and Layers, or any combination of these.
