Pitch Dimensioning Tool

Pitch Dimensioning Tool
This tool allows you to show the slope of an existing line in the drawing.

You set the behavior of the tool in the tool's dialog:

You may set to tool to decimals or fractions, the accuracy to be used, and the base number. In the metric world, slopes are typically expressed in terms of 300 -- simply because 300mm is very close to the 12-inch base that's used in the U.S. Or you may choose a rise of 1 so the tool can be used for slopes.

To use the tool, you click on a line and move the slope indication into position.
