The Sections Interface in VisionLidar allows users to generate cross-sections along an alignment for detailed surface analysis. These sections can be used to compare existing surfaces with proposed designs, analyze terrain changes, and calculate volumes between different layers.
1. Key Features of the Sections Interface
✔ Automated Section Generation – Creates cross-sections at user-defined intervals along an alignment.
✔ Customizable Offsets and Scales – Adjust horizontal and vertical scaling for better visualization.
✔ Reference Surface Comparison – Compare original terrain with a design surface (e.g., road or embankment).
✔ Volume Calculations Between Surfaces – Compute cut/fill volumes between multiple layers.
✔ LandXML Export Support – Easily export cross-sections for external use in civil engineering software.
2. Key Section Parameters and Settings
Section Configuration
Option | Description |
|---|---|
Section Name | Name of the section configuration (appears in the tree structure). |
Surface | The base surface used to generate the cross-sections. |
Scales | Horizontal and vertical scaling for section visualization. |
Offset | Distance on each side of the alignment to include in the section. |
Interval | Defines the distance between two consecutive sections along the alignment. |
Reference Line | List of available alignments for section generation. |
Start / End Chaining | Defines the starting and ending points of the sections along the alignment. |
Reference Surface | Optional secondary surface for comparison (e.g., road surface vs. terrain). |
Drawing and Viewing Sections
Option | Description |
|---|---|
Preferences | Selects the section drawing style, as defined in preferences. |
Draw | Displays sections in the main window. |
Erase | Removes drawn sections from the main window. |
View | Opens the section viewer for detailed inspection. |
Report | Generates a volume report for cut/fill calculations. |
Drawing Origin & LandXML Export
Option | Description |
|---|---|
Drawing Origin | Specifies the first section’s origin in the drawing. Right-click to set by point number or coordinate. |
Update Cross-Sections | Adds new sections along the alignment for LandXML export. |
Volume Calculation Between Two Layers
Option | Description |
|---|---|
Add Volume Calculation | Adds a volume computation between two surfaces. |
Name | Assigns a name to the volume calculation (displayed in reports). |
Origin | Selects the original layer for volume calculation. |
Reference | Defines the reference surface for cut/fill comparison. |
3. Best Practices for Cross-Section Management
✔ Use reference surfaces to analyze design differences between existing and proposed projects.
✔ Optimize offset values to ensure all relevant features (e.g., road shoulders, embankments) are included.
✔ Set appropriate intervals for better accuracy while keeping computation time reasonable.
✔ Enable volume calculations to track earthwork requirements and material quantities.
✔ Export LandXML files for seamless integration with CAD and civil engineering software.
