HVAC zones

New feature to Revit MEP 2009 is Zones. Zones will allow engineers break up the rooms in the building in to, based on engineering volumes. This adds another great tool that is part of the typical mechanical design work flow for system equipment selection as well as to perform accurate heating and cooling loads calculations.


The new zones integrate seamlessly into the current tools of Revit MEP. Zones will have the ability to export the newly created HVAC zone datafor use in the IES. Heating and cooling loads reports have also been enhanced to reflect the powerful HVAC zones and spaces functionality.

AutoCAD's 2009 Ribbon Bar

If you have seen AutoCAD 2009 release you know that Autodesk has change the interface. I noticed that if you have been modifying the dashboard and setting that up in 2008, it is no long in the 2009 release. The new "Ribbon" interface has replaced the dashboard. You can see a screen shot of the Ribbon from a previous post below.

Some new commands that will help you with the new interface:

ribbon - this command turns on the ribbon bar
ribbonclose - this command turns off the ribbon bar
menubar - this is a new system variable <0> menus turned off and <1> menus turned on

Hope this helps you in setting up your new 2009 seats of AutoCAD.
