`LAB`

Controls the degree of tessellation used in the calculation of area properties. If

= DEFAULT, area calculations will use the degree of tessellation set through the`LAB`

**/FACET**command. If= FINE, area calculations are based on a finer tessellation.`LAB`

Calculates and prints geometry statistics (area, centroid location,
moments of inertia, volume, etc.) associated with the selected areas.
**ASUM** should only be used on perfectly flat areas.

Geometry items are reported in the global Cartesian coordinate system. A unit thickness is assumed unless the areas have a non-zero total thickness defined by real constant or section data.

For layered areas, a unit density is always assumed. For single-layer areas, a unit density is assumed unless the areas have a valid material (density).

The thickness and density are associated
to the areas via the **AATT** command.

Items calculated via **ASUM** and later retrieved
via a ***GET** or ***VGET** command
are valid only if the model is not modified after issuing the **ASUM** command.

Setting a finer degree of tessellation will provide area calculations with greater accuracy, especially for thin, hollow models. However, using a finer degree of tessellation requires longer processing.

For very narrow (sliver) areas, such that the ratio of the minimum
to the maximum dimension is less than 0.01, the **ASUM** command can provide erroneous area information. To ensure that
the calculations are accurate, subdivide such areas so that the ratio
of the minimum to the maximum is at least 0.05.
