Aeccland.shx _verified_ ✰

You are likely using standard, plain AutoCAD, while the original creator was using Civil 3D. Since standard AutoCAD doesn't include the Civil 3D/Land Desktop support libraries by default, it doesn't know how to render the symbols. What Happens if You Don't Have It?

If you are editing the linetype file manually, ensure that the shape name ( TREE , CIRCLE , etc.) exactly matches the shape definitions inside aeccland.shx . A single typo will cause the entire linetype to fail.

If you are a recipient of a drawing (not the original author), you have three primary methods to resolve this error. aeccland.shx

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.

The file is usually installed with Civil 3D. If it is missing, search your local C: drive to see if it was moved, or repair your installation. 3. Redefine the Linetype (Advanced) You are likely using standard, plain AutoCAD, while

To permanently remove dependency on :

Instead of defining letters and numbers, it defines specialized structural shapes. For instance, a civil linetype representing a dense row of shrubbery references a "TREE" or "HEDGE" block script contained inside aeccland.shx . If you are editing the linetype file manually,

Paste the file into your local AutoCAD Fonts directory. The standard path is usually: C:\Program Files\Autodesk\AutoCAD 20XX\Fonts\

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