This tool displays the area and perimeter of a selected hatch. Because hatching can be an extremely detailed collection leaving room for error, it temporarily solid fills the area that it has determined. Visually confirm the solid filled area matches.
Keyboard Command: HatArePer
The hatch must be a true hatch object. Hatching done in AutoCAD versions prior to R14 were not true hatch objects but rather a bound collection of linework.
