Measure Area

A Measure Area annotation reports the enclosed area and the perimeter of a picked polygon, written as a single label at the centroid — for example Area: 412.500 sq ft, Perimeter: 84.250 ft.

Pick the boundary points and the shape closes automatically; the area comes from the closed polygon regardless of the order you picked, so a re-entrant or non-convex outline still measures correctly. Because the points snap like any other CAD geometry, tracing an existing deck outline or a hatched region is exact rather than eyeballed.

Use it for quantity checks — deck surface, parapet elevation area, a patch of overlay, a plan footprint — where you want the number on screen but not a formal dimension in the drawing.

Text and units

Label: Override text, replacing the measured values.

Prefix / Suffix: Text before and after the value.

Precision: Number of decimal places.

Unit Style / Length Unit: Units. Length Unit overrides the project geometry unit for this annotation only; the area is reported in the corresponding squared unit.

Typography

Text Height: Text size in real units.

Font Family / Font Weight / Font Style: Font controls.

Notes

Both numbers are recomputed from the polygon whenever a boundary point moves, so editing the outline updates the quantity — there is no stale value to remember to refresh.

For a measurement that belongs in the issued drawing, use the dimension objects instead; Measure Area is the working tool. Related: Measure Length.
