Drawing Profile Lines

A profile line defines the cross section or area that is displayed in the profile window. The line is made up of a start point, end point, and depth to define the area of the cross section. The points that are displayed in the profile window originate from the Active LAS Layer. The points that are drawn in the Profile Window (meeting the intersection criteria described above) are 100% of the points in the LAS files referenced by the active LIDAR Layer.

4. Move the mouse perpendicular to the line to specify the depth or width of the profile line. Click at the desired depth to complete the profile line.

To input an exact depth, right-click and then enter the depth value and press "Enter". Alternatively, if a profile line has been drawn earlier and a width was defined for it, you can double-click after defining the end point on the line you are drawing now to use the same width as previously defined.
