Road Analysis Module FAQ

Clearance Analysis

1. [Clearance Analysis] Failed to register scalar field 'ClearanceID'.
   • Error Reason: Failed to register additional attribute fields. The point cloud may be occupied by another program, or the LiData version is lower than 2.0.
   • Solutions: Close the occupying program and upgrade the LiData file version.

Hight Limit Analysis

1. [Hight Limit Analysis] No ground points to drape.

   • Error Reason: The analysis location lacks ground points.
   • Solution: Ensure that ground points exist in the analysis location and that the ground point category is correctly specified.

2. [Hight Limit Analysis] Layer '' was deleted.

   • Error Reason: The power line layer has been deleted.
   • Solution: Re-analyze and recalculate using Hight Limit Analysis.

3. [Hight Limit Analysis] Config record was deleted.

   • Error Reason: The relevant configuration for the analysis has been deleted.
   • Solution: Re-analyze and recalculate using Hight Limit Analysis.

Place Tile Array

1. [Place Tile Array] No trajectory segments.
   • Error Reason: No trajectory segments.
   • Solution: Select the trajectory segments on the 3D view trajectory first, then proceed with processing.

Section Analysis

Section Engineering Management

1. [Warning] "Cannot switch active project now"
   • Error Reason: The section engineering cannot switch the active project while the calculation is in progress and the 2D display window is open.
   • Solution: Wait for the calculation to finish and close the 2D display window.

Calculation Attribute

1. [Warning] "No valid data"
   • Error Reason: Measurement section has not been generated.
   • Solution: Generate the measurement section for the current group.

Export Section

1. [Warning] "Something wrong happens when exporting sections"
   • Error Reason: Export failed.
   • Solution: Remake the sections or contact technical support.
2. [Warning] "Export failed"
   • Error Reason: There is currently no active section project, leading to export failure.
   • Solution: Right-click on the section directory management number to activate the active project.
3. [Warning] "Import failed"
   • Error Reason: 1. There is currently no active section project, leading to export failure; 2. The data input path is empty.
   • Solution: 1. Right-click on the section directory management number to activate the active project; 2. Enter the correct data path.
4. [Warning] "No valid section"
   • Error Reason: No measurement section for the cross-section.
   • Solution: Generate the measurement section.
5. [Warning] "Exporting section failed in: ..."
   • Error Reason: The specified measurement cross-section was not found.
   • Solution: Rerun the calculation of the measurement section to synchronize the data.
