Is there a way to measure the perimeter of a building?
Walk around it and count your steps. Just kidding! In "Area Mode", create an area for the entire building then right click on it. It will be under "Info".
You could also switch to SITE mode and generate a building outline. I think this creates a closed polygon. You can click on it for area, permiteter, and volume if you give it a height.
This also comes in handy as you can export the building outline as a dwg for import into a PDF if you have something more than reader.
Thanks guys for the help.
