If you do not close the polygon, AutoCAD calculates the area as if a line were drawn from the last point entered to the first. AutoCAD calculates the area and perimeter and returns the total area of all the areas defined by selecting points or objects since Add mode was turned on. Specify next corner point or press ENTER for total (ADD mode): Specify a point (2) All points must lie in a plane parallel to the XY plane of the current UCS. Specify first corner point or : Specify a point (1) or enter an optionĬalculates the area and perimeter you define by selecting points.
You can use the Subtract option to subtract specified areas from the total area. The Add option calculates the individual areas and perimeters of defined areas and objects as well as the total area of all defined areas and objects. Turns on Add mode and keeps a running balance of the total area as you continue to define areas. this feature is built into the area command already.
