Measuring slope
You'll use the Elevation Tool to measure the change in elevation between a starting location and an ending location.
To measure the change in elevation:
1 Click the Elevation Tool.
2 Hold down CTRL, then hold down the left mouse button on the starting location.
3 Drag the mouse along the slope to the ending location.
4 Release both the CTRL key and the mouse button at the slope's ending location.
The difference in elevation is shown in the default unit of measure on the Status Bar.
