Aeccland.shx !new!

: To prevent this for others, use the eTransmit command in AutoCAD, which automatically packages all necessary dependent files, including shape files, into a single ZIP.

If the reference persists, use the tool inside the Civil 3D Prospector tab.

It sounds like you have stumbled upon one of the most important "hidden" tools in AutoCAD, particularly if you work in Civil 3D or Land Desktop.

Because the font is constructed of simple linear strokes rather than complex Bezier curves, it offers:

Below is an overview of what this file is, why it often goes missing, and how to resolve the errors it causes. What is aeccland.shx?

When the missing SHX warning appears, AutoCAD offers a substitution dialog. You can manually choose a replacement:

Understanding the root cause of the error is the first step to fixing it. The aeccland.shx error typically appears under four common scenarios:

Here are the most effective ways to resolve this error, ordered from easiest to most permanent. 1. Place the File in the Same Folder as the Drawing

In the Autodesk ecosystem, .shx files are built from plain-text ASCII shape definition source code ( .shp ). AutoCAD reads compiled .shx binary files much faster than uncompiled paths, optimizing computer performance when rendering complex layouts.

Here are some features and facts about "aeccland.shx" and its potential use:

[aeccland.shp] ---> (Compiled via AutoCAD) ---> [aeccland.shx] (Human-readable text) (Binary resource file)

Instead of dictating text styles, it stores compiled geometry embedded directly into a matching linetype file ( aeccland.lin ). Civil engineers use these to map topographical features—such as stone walls, tree lines, or utility markers. When a drawing calls for a custom civil linetype, AutoCAD queries aeccland.shx to fetch the specific vector shapes needed to build that line pattern. Why the "Missing SHX File" Error Occurs

Some complex linetypes (e.g., gas lines, water mains, or contour labels) in older civil drawings are hard-coded to reference the shapes inside aeccland.shx . Without it, these linetypes will not generate correctly.
