Aeccland.shx Link
To understand aeccland.shx, you have to understand the format.
Most people know .shx files as Fonts (like txt.shx or romans.shx). However, AutoCAD also uses .shx files for Complex Linetypes. If you want a line that looks like a fence, a gas line, or a row of trees, the definition for those "shapes" lives inside an .shx file.
If you have access to a computer that still runs Autodesk Land Desktop (or an old Civil 3D version pre-2010), locate the file:
Copy this file to your current AutoCAD Fonts directory:
After copying, restart AutoCAD. The error should disappear permanently. aeccland.shx
Note: Autodesk no longer officially distributes this file as a standalone download due to deprecation of Land Desktop.
In many cases, the drawing does not actually require aeccland.shx—it was simply the default font of a template. To purge the reference:
If you manage a team of drafters, you can prevent "aeccland.shx missing" errors from ever appearing.
Yes. Because aeccland.shx is obsolete and unsupported, many firms have migrated to: To understand aeccland
If you need specific land surveying symbols (e.g., property corner dots, monument symbols, or bearing ticks), consider using Shape files from the mapbase.shx or geomap.shx included with AutoCAD Map 3D.
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:
In the case of aeccland.shx, the file serves a dual purpose within the AutoCAD Architecture environment: Most people know
The name is a dead giveaway if you break it down:
This specific file contains the shape definitions for Civil Engineering linetypes. Without this file loaded, your survey drawings would look like broken text or question marks.
Common shapes defined inside aeccland.shx include:
Understanding how aeccland.shx fits into the SHX ecosystem helps with diagnostics.
| File Name | Category | Purpose | Replacement Risk |
| :--- | :--- | :--- | :--- |
| aeccland.shx | Shape Symbol | Site planning, trees, utilities, contour arrows | High (Drawing breaks) |
| romans.shx | Text Font | Standard roman simplex font | Low (Letter substitution) |
| ltypeshp.shx | Shape Symbol | Standard linetypes (GAS, HWY, Fence) | Medium (Lines become solid) |
| aecblk.shx | Shape Symbol | Architectural door/window tags | Medium |
| aaaahx.shx | Text Font | AEC hatching text | Low |
Key distinction: Most people only worry about text fonts. aeccland.shx is a shape file for geo-spatial data. Losing it loses data, not just aesthetics.
