Good Day everyone:

I have a question about the installnation. I already install my Revit Architectural 2009 in imperial unit template and library. However, now I got a new project need to be use metric unit. How should I add metric unit into my program? The only way I can think is uninstall and reinstall Revit Architectural. Is there any easy way to do this? Just like other softwares, some of them have the ability to add the option. Thanks for your help!
