Geometric Options

Geometric options are available from the Geometric menu. They calculate the length of lines and the perimeters or areas of polygons in a particular feature layer. These options perform calculations on fields in the data store, but the results of these calculations are not saved back to the data store. In AutoCAD Map, you can create a calculated field to store this information. These functions are available for every data provider except for raster, WFS, and WMS providers.

To use these options, select the object whose length or area you want, and then create the exact expression shown in the example below. Do not replace the argumentGeometry with an actual vaue.

Option	Definition	Syntax	Example
LENGTH2D	Calculates the length of lines and perimeters of polygons	LENGTH2D(Geometry)	LENGTH2D(Geometry)
AREA2D	Calculates the area of a polygon	AREA2D(Geometry)	AREA2D(Geometry)
