Length Measurement

The Length measurement tool places specialized markups that calculate a single, linear measurement. Length measurements can be given depth or a slope.

For the measurement of multiple line segments plus their cumulative length, see Polylength Measurements. For just the cumulative length of a multi-segment line, see Perimeter Measurements. For a similar markup without a measurement, see the Dimension 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.
