046] Global Mapper - Parallel Line Offset: Create Parallel Lines Spaced from Selected Line Feature(s)

Today, we will explore the "offset" function, which is commonly used in CAD software.

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.

First, draw a line on the screen and select it.

[img 2 : Right-click menu showing Advanced Feature Creation Options]

Right-click - Select Advanced Feature Creation Options - Create Parallel Lines Spaced from Selected Line Feature(s).

The settings window will then appear.

  • 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.

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.

My body feels a bit sore after spending the day carrying, bending, and cutting pipes. That's all for today!

This is the first session of the Global Mapper series. Among the many things you can create using GIS software, I plan to cover topics essential for preparing landscape-related reports, such as: Creating a DEM (Digital Elevation Model) Using Online Maps Contour, Slope, and Aspect Analysis Path Profiling (Terrain Sections) Viewshed Analysis Using the Map Layout Editor for saving images in Global Mapper As with my CityEngine series, I believe in getting started first to build a framework as posts accumulate. I won't go into every tiny detail right from the start; instead, I will provide deeper explanations and supplementary information as we progress. First, you'll need to download the trial version. If you visit the  Blue Marble Geographics  website, you will see a menu for a "Start Free Trial." Please note that personal emails (Naver, Gmail, etc.) are generally not accepted; you must use an email associated with a ...

However, in actual CAD drawings you receive, the parcels and the planned elevations are often placed on separate layers. Of course, if there are only one or two, you could manually enter the elevation value for each parcel, but if there are hundreds of parcels, the story changes. Take a look at the data below.
