AECCLAND.shx is a specialized shape file used primarily in Autodesk Civil 3D and Land Desktop environments to define complex custom linetypes. Core Purpose and Function
Unlike standard SHX files that typically act as vector-based text fonts, AECCLAND.shx 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 encounter errors when opening a drawing, it is usually because the file was not included in the project transmittal.
Standard Location: For Windows users, the file is typically stored in the AutoCAD Fonts folder, located at: C:\Program Files\Autodesk\AutoCAD 20xx\Fonts. Resolution:
Request from Source: Ask the drawing creator to send the aeccand.shx, aeccland.shp, and aeccland.lin files.
E-Transmit: 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.
Manual Installation: If you obtain the file, copy and paste it into the AutoCAD Fonts directory to stop the recurring prompts. Managing PDF Output Missing Shx File(s) - Forums, Autodesk
I notice you're asking me to create content for a file named aeccland.shx. Based on the extension .shx, this appears to be a shape file index used in AutoCAD or other CAD/GIS software, specifically part of a shapefile pair (.shp + .shx + .dbf).
However, I cannot directly generate a compiled .shx binary file here, as it's not a simple text file. But I can help you in several ways:
If you are a recipient of a drawing (not the original author), you have three primary methods to resolve this error.
aeccland.shx is the unsung hero of civil drafting. It is the visual dictionary that tells AutoCAD how to draw the complex symbols surveyors rely on—turning simple polylines into intelligent representations of the physical world.
If you are looking at this file because you are missing it, you likely need to install the AutoCAD Civil 3D Object Enabler or copy the file from a colleague's C:\Program Files\Autodesk\AutoCAD 20xx\Fonts folder.
aeccland.shx is a specialized AutoCAD Compiled Shape File used primarily in land development and civil engineering projects created with Autodesk Land Desktop or AutoCAD Civil 3D.
This file functions as a container for shape and font definitions, allowing CAD software to efficiently render custom symbols and complex linetypes used in site grading, parcel layout, and surveying. Core Functions of aeccland.shx
The file is essential for the visual integrity of drawings that rely on specific civil engineering symbology. Its primary roles include:
Defining Linetypes: Many custom civil engineering linetypes (like those for property boundaries or silt fences) use shapes stored within aeccland.shx to display correctly.
Symbol Rendering: It traditionally contains shapes like "Stone" and "Circle", which are used as building blocks for more complex drawing elements.
Performance Optimization: Unlike TrueType Fonts (TTF), SHX files use simple vector strokes, which allow for fast rendering in large-scale infrastructure drawings without sacrificing system speed. Troubleshooting "Missing SHX File" Errors
If you open a drawing and receive a warning about a missing aeccland.shx file, it usually means the sender used Land Desktop or Civil 3D symbols that your local installation cannot find. 1. How to Fix the Error
To resolve the issue, you must place a copy of the file in a directory that AutoCAD searches. Missing Shx File(s) - Forums, Autodesk
If you are seeing a prompt for aeccland.shx, it means your drawing is looking for a specific shape file originally bundled with Autodesk Land Desktop. Even if you don't use Land Desktop anymore, this file is often "baked" into custom linetypes—like those used for hedges, treelines, or complex site boundaries. 🛠️ Why does it keep popping up? aeccland.shx
Legacy Data: You’ve received a drawing from someone who used Land Desktop or a custom template.
Custom Linetypes: Your drawing uses linetypes (like TREELINE or BUSH) that reference shapes stored inside that specific .shx file.
Missing Support Path: The file exists on your computer, but AutoCAD doesn't know where to look for it. ✅ How to fix it:
The "Quick Fix": If you don't care about the specific shapes (like little tree icons in a line), you can just hit Cancel or Ignore when the box pops up. AutoCAD will usually substitute a simple line.
The "Permanent Fix": Find a copy of aeccland.shx (it is widely available in Autodesk community forums) and drop it into your AutoCAD Support folder.
The "Pro Fix": Use the PURGE command or specialized tools like Batch Save Utility to strip out legacy DGN linetypes and shapes if they aren't actually needed in your project.
Stop the "missing file" madness! Save this for the next time your CAD manager asks why the treelines look like dots.

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
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 AECCLAND
If you need the linetypes to display correctly, you must place the file where AutoCAD can find it. Where to find it
: 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:
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

The Complete Guide to aeccland.shx: Resolving AutoCAD SHX File Errors and Font Mismatches
Best Practices for CAD Managers
If you manage a team of drafters, you can prevent "aeccland.shx missing" errors from ever appearing.
- Standardize Fonts: Do not rely on vertical product SHX files for critical data. Convert all site symbols to vanilla AutoCAD blocks.
- ETRANSMIT: When sending drawings to clients or consultants, always use the
ETRANSMIT command. This packages all dependent SHX files into a ZIP file automatically.
- PDF Underlays: Before sending a DWG, create a PDF. Even if the client loses the SHX file, they have a visual reference of what the symbols should look like.
- Migration: If upgrading from AutoCAD Architecture 2015 to 2025, note that
aeccland.shx rarely changes, but the path may shift. Copy the file manually if running side-by-side installations.
The Legal and Ethical Consideration
It is important to note that aeccland.shx is a copyrighted Autodesk file. While you may copy it from a legally owned licensed copy of Land Desktop for personal or internal business use, redistributing the file publicly (e.g., uploading to a free font website) violates Autodesk’s End User License Agreement. Always obtain the file from your own licensed legacy software.
