Missing Line - How to Use

Use "Missing Line" as a live tape measure, giving you height, slope, and distance information

1. Open Your Project: Start by opening any project on your tablet.
2. Select "Missing Line": You can find "Missing Line" on the home screen menu or in the side menu within your CAD view.
3. Measure Values: The application uses the measured values between locations, so you don't need to worry about station or point coordinates.

You're ready to use the "Missing Line" feature.

Clarify what you are measuring

Before you again, recognize that you are going to be measuring the distance, angle, slope, and height between two points. Find the first point you would like to measure from, and when you are ready, press the red measure button.

Once this is measured, your instrument is going to give you a “live read” of the measuring data from that point. For instance, if you measured your first point with a prism, as the instrument follows the prism as you move, it will automatically start reading out dimension data to you regarding the measurements of your location back to that original starting point.

To “lock in” the second point for this application, simply press the red measure button again. Press the green check mark or the back button to restart the application.

Understanding the Data

Pulling out the menu screen on the right, you will notice that the measurement information is blank before you begin, but after measuring your first point, the data will populate.

In the example below, the distance from our first point measured to the second point is a horizontal distance (HD) of 5.463m, a slope distance (SD) of 5.892m, and a difference of height (dH) of 2.207m). Notice the HD is exact horizontal distance between the two points, without taking the difference of height into account. The SD, or slope distance, is the data that incorporates the diagonal distance between the two points, considering their height difference.

The “tilt” data describes the incline angle from the first point to the second point. You will see this incline described in both percentage format, as well as degrees.
