Compared with AREA command, AREASUM tools is more flexible and powerful. When using the traditional area command, users usually need to redraw the boundary of the region, or convert the boundary into a single object, and then get the area of the closed region.

When the boundary is not a single object, AREASUM tool can automatically search the boundary of a complex graphic. After selecting multiple closed regions, the command line will add the current region value and area sum sequence faster in real time. You can access it from Menu: Express tools>Modify>Areasum.

After picking points, the command line will show up in real time the region value sequence and area sum in (mm2):
