Perimeter Measurement

The Perimeter measurement tool places specialized markups that calculate the length of all sides of a given shape or of a multi-segment line. Perimeter measurements can appear to be similar to Area Measurements, but they are not closed shapes; even when they are created such that their start and end points touch, they are always treated as open shapes. Perimeter measurements can be given depth, if desired, though they cannot be assigned a Rise/Drop value (for a similar measurement that can be given a rise or drop value, see see Polylength Measurements.

For single length measurements, see Length Measurements. For a similar markup without the measurement, see the Polyline Tool.

Before placing a measurement, it is recommended that you set the page scale for the document first. When trying to place a measurement on a page that does not have a page scale, you will be prompted to set the scale.
