Engineering drawings often use "Treeline" or utility lines that require recurring symbols. The software references this file to draw these symbols efficiently without bloating the file size. Common Usage Scenarios
When a linetype in a drawing references a shape stored inside aeccland.shx , AutoCAD looks for this file to draw the symbol correctly on the screen. Why am I Seeing the "aeccland.shx" Error?
: You received a drawing from someone who used Land Desktop or a template containing its linetypes, but they did not include the .shx file in their delivery. Software Migration
specifically contains shape definitions used in legacy Civil and Land Desktop linetypes. Because these linetypes are still embedded in many templates and project drawings, AutoCAD continues to look for the file decades after Land Desktop was retired. Why the Error Happens You will see a "Missing SHX" prompt if: Project Collaboration If you want to stop the error without
If you are a recipient of a drawing (not the original author), you have three primary methods to resolve this error.
The warning message: "One or more SHX files are missing: aeccland.shx" typically occurs for three main reasons:
Aeccland.shx is typically a , meaning every character occupies the same amount of horizontal space. This is a critical feature for civil engineering drawings for several reasons:
A: The drawing contains a reference to the file (perhaps in a frozen layer or a hidden viewport) even if no visible geometry uses it. Use -PURGE > Regapps to remove the reference. Replace or Purge the Reference : If you
Unlike standard SHX files that typically act as vector-based text fonts, is a "shape" file. It stores geometric symbols—most notably "Stone" and "Circle" —that are embedded into linetype definitions used for civil engineering and landscaping plans. When a drawing uses a linetype that requires these shapes, AutoCAD must "see" this file to render the line correctly; otherwise, it may display question marks or trigger a "Missing SHX File" warning. Troubleshooting Missing AECCLAND.shx
If you have the file from a colleague or a backup, you must place it in a folder AutoCAD can see:
On a typical Windows installation, it is usually found in the font directory, such as C:\Program Files\Autodesk\AutoCAD 20xx\Fonts . Known Issues & Troubleshooting
Most people only worry about text fonts. aeccland.shx is a shape file for geo-spatial data . Losing it loses data, not just aesthetics.
It compiles from an uncompiled ASCII text shape description file ( .shp ) into a lightweight, high-performance binary file ( .shx ) so AutoCAD can regenerate complex drawing maps instantly without experiencing hardware lag. Why Is the "Missing aeccland.shx " Error So Common?
