Basic properties

This part of the Mass Properties window is always displayed. The exact items displayed on the left side vary depending on the last element measured and the tool used to measure it.

Length

Length, in working units, of a linear element. For surfaces, the length of the wireframe geometry.

Perimeter

Perimeter, in working units, of a closed planar element.

Surface Area

Area of a closed planar element or the surface area of solids in square working units.

Volume

Volume enclosed by a solid, in cubic working units.

Mass

Mass, computed by multiplying the Length, Surface Area, or Volume by the Mass Per <Length/Area/Volume> setting.

Centroid

Coordinates, in working units, of the center of mass.
