Align Vertical - How to Use

How to Use the Align Vertical Application

1. Open Your Project: Start by opening any project on the tablet.
2. Open Application: Open the Align Vertical 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 Align Vertical application.
3. Select the First Point (Base Point): Measure the first point on the vertical surface using either direct measurement or an existing control or layout point.
   • Select the three‑triangle icon to set this point as the base point.
   • This base point is used as the vertical reference for all subsequent measurements.
4. Measure Additional Points: Move the camera to the next point on the same vertical surface to read the measurements and correction values.
   • HD (Horizontal Distance): The horizontal distance measured from the true vertical line of the base point to the current measured point.
   • SD (Slope Distance): The direct slope distance measured from the base point to the current measured point.
   • dH (Height Difference): The true vertical height difference between the base point and the current measured point.
5. The following corrections are displayed:
   • Right / Left:
     • Right indicates that the measured point is positioned to the left of the base point and must be corrected to the right by the displayed value.
     • Left indicates that the measured point is positioned to the right of the base point and must be corrected to the left by the displayed value.
   • Forward / Backward:
     • Forward indicates that the measured point is positioned closer to the total station and must be moved away from the total station by the displayed value.
     • Backward indicates that the measured point is positioned farther from the total station and must be moved toward the total station by the displayed value.
6. Repeat this step for all points that need to be checked for vertical alignment.

Correction values displayed after measuring a second point:

• Right / Left:
  • Right indicates that the measured point is positioned to the left of the base point and must be corrected to the right by the displayed value.
  • Left indicates that the measured point is positioned to the right of the base point and must be corrected to the left by the displayed value.
• Forward / Backward:
  • Forward indicates that the measured point is positioned closer to the total station and must be moved away from the total station by the displayed value.
  • Backward indicates that the measured point is positioned farther from the total station and must be moved toward the total station by the displayed value.

Explanation of the measurements:

P1 is the base point, P2 is the current measurement of the 2nd point

• HD (Horizontal Distance): The horizontal distance measured from the true vertical line of the base point to the current measured point. (P* to P2)
• SD (Slope Distance): The direct slope distance measured from the base point to the current measured point. (P1 to P2)
• dH (Height Difference): The true vertical height difference between the base point and the current measured point. (P1 to P*)

Examples of Using the Align Vertical Application

The Align Vertical application is commonly used to verify vertical accuracy during installation and construction tasks.

Example 1: Checking Wall Verticality

The application can be used to verify whether points along a wall are vertically aligned.

• Set the base point at the bottom of the wall
• Measure additional points higher up
• Review correction values to identify deviations

This helps ensure walls are plumb.

Example 2: Verifying Column or Pillar Alignment

Columns or pillars can be checked for vertical alignment.

• Set the base point at the base of the column
• Measure points along the height of the column
• Use correction values to determine if adjustment is required

Example 3: Aligning Facade Elements

The application can be used to verify the vertical alignment of facade panels or structural elements.

• Set a base point on the first panel
• Measure points on adjacent panels
• Compare correction values to ensure consistent vertical alignment

Example 4: Checking Vertical Installation of Pipes or Shafts

Vertical pipes, shafts, or ducts can be checked during installation.

• Measure the lower reference point
• Measure higher points along the installation
• Use the correction values to confirm vertical installation

Example 5: Quality Control and Verification

Align Vertical is useful for quick quality checks.

• Identify deviations early
• Reduce rework by correcting alignment issues immediately
