Width Between Lines
Function Description: Specifies a target line, densifies its nodes, and calculates the distance between each densified node and a reference line. Results are represented as vector lines.
Steps
- Click the Distance Between Lines 
 tool to open the settings dialog. 
 Parameter Description
- Result Layer: The layer where the calculated distance lines will be saved.
 - Sampling Interval: The interval for node densification on the target line (default: 1 meter).
 - Calculate Line Nodes:
- Checked: Distance is calculated for both original nodes and sampled points.
 - Unchecked: Distance is calculated only for sampled points.
 
 
Left-click to first select the target line, then click the reference line. Right-click to cancel and reselect.
- Click Calculate to generate results.
 
 Example: Yellow line = Target line, Red line = Reference line
 Result: Distance lines (vector representation)
