I ran into the "Missing SHX File" error when opening a civil drawing today. The file in question was aeccland.shx .
The file to display specialized civil engineering symbology, custom linetypes, and technical text fonts. If you have ever opened an AutoCAD drawing from a consultant or surveyor and been interrupted by a "Missing SHX Files" dialog box, there is a very high probability that aeccland.shx was one of the missing assets.
Because Land Desktop is no longer supported or installed on most modern systems, these files are often missing, causing AutoCAD to display an error message whenever it attempts to load a drawing that references them.
. Although the .shx file is the compiled version that AutoCAD actually uses, including the source .shp file can be helpful for troubleshooting or if you ever need to modify the shape definitions. aeccland.shx
. In AutoCAD or Civil 3D:
Use the FONTALT command to substitute missing fonts with a standard one like simplex.shx .
: It is often located in the support folders of older installations, such as C:\Program Files\Land Desktop 2005\Support Where to put it I ran into the "Missing SHX File" error
3. Manually Place the File in Your AutoCAD Support Directory
Please let me know if you would like me to:
The 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 If you have ever opened an AutoCAD drawing
At its core, aeccland.shx is a used by Autodesk’s civil engineering products. Unlike standard text font files (which also use the .shx extension), this file contains geometric shape definitions that are called upon by complex linetypes.
While aeccland.shx looks like just another system file, it is actually a that contains a specialized set of symbols known as the Linetypes for Civil/Survey .
Once found, copy both aeccland.shx and aeccland.shp to a location that is included in AutoCAD's . The easiest approach is to place them directly in the same folder as the problematic drawing, then reopen the file.
The most frequent encounter users have with this file is a warning dialog stating that AeccLand.shx is missing when opening a drawing. Missing Shx File(s) - Forums, Autodesk
