When you receive a drawing from a consultant or colleague, that drawing might contain custom linetypes or symbols that reference aeccland.shx . If your computer does not have this file in its AutoCAD search path, AutoCAD will alert you. Common causes include:
COMPILE aeccLand.shp
If you don't need the custom linetypes, you can remove the error permanently:
You then compile this with:
The prefix "aec" in "aeccland.shx" suggests that this particular shape file might be related to Architectural, Engineering, and Construction (AEC) content, possibly specifically for landscape or land development designs.
If you are receiving this error frequently, I can guide you on how to set up a shared CAD standards folder to prevent it. Or, if you need help finding the specific download link for your version of AutoCAD, please tell me which version you are using. Missing Shx File(s) - Forums, Autodesk aeccland.shx
Unlike standard SHX files that typically act as vector-based text fonts, 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.
