Slope - How to Use

  • Updated

The Slope application is used to measure and evaluate the geometry of a slope between two points. It provides detailed information such as start and end heights, horizontal distance, and slope inclination expressed in both percentage and degrees.

To use the Slope application, the tool must be stationed. For more information on stationing, please see this article.

A helpful video of the application can be found below:

How to Use the Slope Application

  1. Open Your Project: Start by opening any project on the tablet.
  2. Open Application: Open the Slope application either from the home screen or from the side menu in the CAD view.
    • If the application is not available on the home screen, select Add Shortcut and add the Slope application.
  3. Choose the Function
    • On the right side of the screen, select one of the available functions:
      • Capture
      • Mark
    • Each function serves a different purpose within the Slope workflow.

How to Use the Capture Function

The Capture function is used to measure two points and calculate slope information between them.

  1. Measure the Start Point: Move the camera to the first point of the slope (for example, the bottom of the slope).
    • Select the three‑triangle icon to measure and capture the coordinates of the first point.
  2. Measure the End Point: Move the camera to the second point of the slope (for example, the top of the slope).
    • Select the three‑triangle icon again to measure and capture the coordinates of the second point.
  3. Review Slope Information: After both points are measured, the slope information is displayed on the right side of the screen, including:
    • Height of the start point
    • Height of the end point
    • Horizontal distance between points
    • Slope inclination in percentage (%)
    • Slope inclination in degrees (°)
  4. This information describes the geometry of the measured slope.

How to Use the Mark Function

The Mark function is used after a slope has been captured. It allows tracking points relative to the measured slope directly on site.

  1. Select the Prism: Select the prism that will be used for tracking layout points and lock the camera onto the prism.
  2. Enter Prism Height Offset: Input the height offset from the prism to the bottom of the measuring tip. This ensures accurate height calculations.
  3. Track the Slope: Move the prism along the slope.
    • The application displays the height difference between the current prism position and the measured slope
    • The information indicates how much higher or lower the current point is relative to the slope
  4. This allows continuous verification while working along the slope.

Examples of Using the Slope Application

The Slope application is commonly used for layout, verification, and quality control tasks involving inclined surfaces.

Example 1: Measuring Staircase Slope (Capture)

The Capture function can be used to measure the slope of a staircase.

  • Measure the bottom step as the start point
  • Measure the top step as the end point
  • Review slope percentage and angle to verify design compliance

Example 2: Measuring Ramp Inclination (Capture)

Ramps can be checked to confirm accessibility or design requirements.

  • Measure the bottom and top of the ramp
  • Review slope inclination in percent and degrees
  • Compare values with project specifications

Example 3: Tracking Slope Height During Installation (Mark)

The Mark function can be used while installing elements along a slope.

  • Capture the slope once
  • Move the prism along the slope
  • Check how much the current position deviates above or below the slope

This is useful for formwork, screed installation, or grading tasks.

Example 4: Verifying Drainage Slopes (Mark)

Drainage or pipe slopes can be verified during installation.

  • Capture the intended slope
  • Track points along the installation
  • Ensure consistent fall along the slope
