Measure Area has been expanded and enhanced in various places.
When you measure areas, the perimeter is also calculated and added up.
The area you are measuring is highlighted in color (new area identification; also in conjunction with many other tools).
You can measure 2D areas automatically using the Area detection tool in the dialog line. To identify cut-outs, you can use Island detection and Inverse island detection.
You can also measure areas in perspective view; the current area is highlighted in color.
