046] How to Create Parallel Offset Lines in Global Mapper
Learn how to generate multiple parallel offset lines from selected vector features at precise intervals.
This tutorial demonstrates the dedicated parallel line creation tool in Global Mapper. We move beyond the old workaround of converting buffers to lines and explore the settings for spacing, directional orientation, and non-overlapping geometry to streamline your GIS drafting workflow.
In this tutorial, we will learn how to create precise parallel offset lines in Global Mapper using the built-in Advanced Feature Creation tool.
Previously, this specific feature was not available in Global Mapper. In the past, we had to draw buffer lines and then convert those buffers back into line features to achieve a similar result.
Let’s get started.
Creating Parallel Offset Lines in Global Mapper
First, draw a line on the screen and select it.
Right-click - Select Advanced Feature Creation Options - Create Parallel Lines Spaced from Selected Line Feature(s).
The settings window will then appear.
Understanding the Parallel Line Settings
- Number of Parallel Lines: The number of parallel lines to be created in each direction.
- Parallel Line Spacing: The distance between the parallel lines. You can change the units here.
- Create Parallel Lines on: Select the direction for line creation. This is based on the direction from the starting point to the end point of the segment.
- Create Non-Overlapping Lines: If the reference line is complex, this option prevents the generated lines from overlapping each other.
When you click OK, a window appears to configure the attributes of the lines to be created.
After adding styles, layer names, and attributes, click OK.
Generated Parallel Offset Line Results
Yes, they have been created correctly.
It’s quite simple. You might find it hard to believe that this feature wasn't available until recently.

That's all for today!
