Aeccland.shx – Latest & Quick
In short, aeccland.shx is the "Rosetta Stone" for site design drawings inside AutoCAD Architecture and Civil 3D.
The humble aeccland.shx file represents a bridge between the early days of CAD-based land development and modern BIM-ready civil infrastructure design. While its active use has faded, its ghost continues to haunt drawings created in the late 1990s and 2000s. By understanding how to substitute, replace, or permanently resolve the missing SHX error, you ensure that your drawing data remains accurate, legible, and professional.
Next time you see the alert "aeccland.shx cannot be found," you will not panic. You will know exactly whether to browse for a substitute, copy the file from an old backup, or purge the text style reference. In the world of legacy CAD data management, that knowledge is power.
Still experiencing issues? Check your AutoCAD Support Paths or consult your IT department to verify that no migration tool (like the Autodesk Migration Utility) inadvertently skipped legacy font folders.

If you are an AutoCAD or Civil 3D user, you have likely encountered the "Missing SHX Files" dialog box specifically requesting aeccland.shx
. This file is a common compiled shape file originally distributed with Autodesk Land Desktop
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?
An SHX file in the AutoCAD ecosystem is a "compiled shape" file. Unlike standard fonts (TTF), SHX files are used to store: Specialized Fonts : Vector-based text styles. Linetype Shapes
: Symbols embedded within complex linetypes, such as those used for "Stone" or "Circle" patterns in civil engineering drawings. aeccland.shx aeccland.shx
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
: 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
: You moved to a newer version of Civil 3D or plain AutoCAD that no longer installs these legacy support files by default. Pathing Issues
: The file exists on your computer but is not in a directory listed in your AutoCAD Support File Search Path How to Fix Missing aeccland.shx
If your drawing keeps asking for this file, use these solutions provided by the Autodesk Support AUGI community 1. The "Ignore" Method (Quick Fix) When the dialog box appears, select "Ignore the missing SHX files and continue."
: The drawing will open, but any linetypes using shapes from aeccland.shx
will appear as simple continuous lines or display incorrectly. 2. Obtain and Install the File
If you need the linetypes to display correctly, you must place the file where AutoCAD can find it. Where to find it In short, aeccland
: It is often located in the support folders of older installations, such as C:\Program Files\Land Desktop 2005\Support Where to put it
: Move the file to your current version's font folder (e.g., C:\Program Files\Autodesk\AutoCAD 2024\Fonts 3. Permanent Removal (Purging)
If you want to stop the error without finding the file, you must remove the references to it: Purge Command command to remove unused linetypes and text styles. Change Linetypes
: If the linetype is in use, you must change it to a standard AutoCAD linetype that does not require external shape files. 4. Automatic Substitution
Aeccland.shx is a vital shape file for AutoCAD Civil 3D and Land Desktop users. It is an "out of the box" compiled shape file that contains essential symbol definitions, such as "Stone" and "Circle," often used in custom linetypes and topographical surveys. Understanding aeccland.shx
In AutoCAD, SHX files (Compiled Shape Files) serve two primary purposes: as text fonts or as symbol fonts for linetypes. Unlike standard TrueType fonts (TTF) used by Windows, SHX files are vector-based and specifically optimized for CAD performance.
The aeccland.shx file is typically bundled with Civil 3D and older Land Desktop installations. It is often referenced in linetype definitions (e.g., in aeccland.lin) to insert specific geometric shapes along a line path. Because it is widely distributed with Autodesk’s civil engineering suites, many CAD managers use it as a standard for creating linetypes that remain compatible across different machines—as long as the software is installed. Common Issue: "One or more SHX files are missing"
A frequent headache for CAD users is receiving a "Missing SHX Files" error when opening a drawing. This happens when a drawing uses a linetype or text style dependent on aeccland.shx, but the file is not in the program's search path. Why it happens: The humble aeccland
Drawing Transfer: The file wasn't included when the DWG was sent from another user.
Missing Support Path: AutoCAD is looking in the wrong folder.
Missing Software: The user may be using standard AutoCAD instead of Civil 3D, which includes this specific shape file by default. How to Fix Missing aeccland.shx Errors
If you are prompted to specify a replacement for aeccland.shx, you have several options to restore your drawing's integrity: Aeccland.shx-shape file needed - AUGI Forums
Sometimes the file exists, but it is corrupted. Symptoms:
Once you have resolved the immediate error, take these proactive steps to ensure it never returns:
When the missing SHX warning appears, AutoCAD offers a substitution dialog. You can manually choose a replacement:
Warning: This method only hides the error. Special survey symbols (like property line bearings, north arrows, or grade markers) will likely display as gibberish or question marks.
AutoCAD will automatically substitute the missing aeccland.shx with a generic font (usually simplex.shx or txt.shx). The result is catastrophic for drawing fidelity:
If you manage a team of drafters, you can prevent "aeccland.shx missing" errors from ever appearing.
