Aeccland.shx [NEW]

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

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

The aeccland.shx file is a specialized compiled shape file used by Autodesk Civil 3D and AutoCAD to define symbols, linetypes, and markers for civil engineering and land development projects. Purpose and Functionality

In the AutoCAD ecosystem, .shx files are vector-based files that define either text fonts or shapes used in complex linetypes. Specifically, aeccland.shx is part of the AEC (Architecture, Engineering, and Construction) object library.

Symbol Definition: It defines specific shapes such as "Tree," "Box," and "Circle" that are embedded within linetypes.

Linetype Rendering: 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

Civil 3D Design: Used for topographic mapping, site planning, and representing physical objects (like trees or hydrants) as part of a custom linetype. aeccland.shx

Standard Directory: 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

One of the most frequent reasons users search for this file is due to a "Missing SHX File" error when opening a drawing from another professional.

The "Dots" Bug: If the file is missing or corrupted, complex linetypes (like a scalloped treeline) may appear as a simple line of dots or arcs. Resolution:

Manual Loading: Use the COMPILE command to recompile the source .shp (if available) or the LOAD command to ensure the shape file is active in the current session.

File Replacement: If the file is corrupted, users often copy a healthy version from a colleague’s computer and replace it in their local Autodesk Fonts folder.

Audit/Purge: For persistent display issues, running AUDIT and PURGE can help clear orphaned data referring to old versions of the shape file.

Are you experiencing a missing file error when opening a specific drawing, or are you looking to customize a linetype using these shapes? ERROR WITH LINETYPE FILE: acad.lin - Forums, Autodesk

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

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

: 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 How to fix corruption:

3. DWG Migration from a Different Workstation

You received a drawing from a colleague, client, or government agency whose CAD template relied on aeccland.shx. The SHX file resides on their local machine but was never transferred with the drawing file.

What is aeccland.shx? (The Technical Definition)

aeccland.shx is a compiled shape file (hence the .shx extension) developed by Autodesk. It is specifically associated with Autodesk AutoCAD Architecture (formerly ADT - Architectural Desktop).

Unlike standard text fonts (like txt.shx or romans.shx), a SHX file can contain two distinct things:

  1. Shape definitions (complex line types, symbols, or linetypes).
  2. Font definitions (text characters).

In the case of aeccland.shx, the file serves a dual purpose within the AutoCAD Architecture environment:

1. If you actually want to create an AutoCAD shape/font definition (.shx is also a compiled shape/font file used by AutoCAD):

You need to write a .shp (text-based shape definition) file first, then compile it using AutoCAD's COMPILE command.

Example of a .shp file (which compiles to .shx):

;; aeccLand.shp - Custom land use symbols
*0,4,AECCLAND
6,2,2,0
*1,6,ARROW
001,2,010,014,002,0
*2,14,TREE
003,5,001,001,001,001,001,001,001,001,001,001,001,0

You then compile this with:

COMPILE aeccLand.shp

Which generates aeccLand.shx
