Measure the horizontal distance between two points
You can measure the horizontal distance between any two points in the viewport. When you click two points, Measure calculates the distance between them on the x-axis. The points do not have to be attached to any elements.
To measure a horizontal distance,
1. Click Annotation, Geometry, or Insert and then, in the Utilities group, click the arrow next to .
2. Click Horizontal. The Measure dialog box opens with the Distance Output box at the bottom.
4. Specify two points by entering coordinates in the user input line, or by clicking in the viewport. After clicking the first point, use the graphical feedback horizontal line as a guide.
The horizontal distance between the two points is displayed in the Distance Output box.
5. Continue specifying pairs of points, or click (Apply) or Cancel to complete the command.
You can click (Apply) to use the output from Measure as input for an interrupted operation.
