If you have custom linetype or hatch pattern definitions stored in other files, place those files in one of the support search paths already defined for the AutoCAD-based product or add the location of your LIN/PAT files to the Files tab of the Options dialog box to use them in the latest release.
After adding custom hatch patterns (PAT files) to AutoCAD, they do not show up as usable hatches within the program.
Causes:
The PAT files have syntax or formatting issues.
The pattern definitions were not properly added to the default AutoCAD PAT file.
The directory path where the PAT files are stored is locked or not recognized as a support path by AutoCAD.
The directory path where the PAT files are stored is a cloud drive or service.
Solution:
Test different PAT files:
Find other hatch pattern files, preferably from a different source, and try them with AutoCAD to verify functionality in the program.
Check pattern definitions:
Be sure that the name of the pattern defined within the PAT file is the same name as the PAT file. For example, if the name of the PAT file is
StoneHatch.pat the first line of the file should read *StoneHatch, (the command needs to be included).
Unblock the PAT files:
Right-click on the hatch file and choose Properties.
Click 'Unblock' and then OK.
Make sure to use correct paths for the PAT files:
Custom PAT files can be put in the default location for hatch pattern files or they can be stored in an alternative location. The path for the alternative location must be added to AutoCAD in Options > Files > Support File Search Path. For MacOS, the path is added in Preferences > Application > Support File Search Path.
Check the formatting of the PAT files:
If customizing either the default acad.pat (imperial) or acadiso.pat (metric) file directly, either change the units of the drawing to match the PAT file's units or edit both PAT files so all the patterns will be seen no matter what units are in a drawing.

This article describes how to install custom hatch patterns in AutoCAD using PAT files.
Solution:
Windows OS
Copy the custom .pat files into the default Support folder (listed below) that AutoCAD uses to find hatch patterns. Added .pat files will cause hatches to be listed under the User Defined or Custom hatch menu within AutoCAD.
Windows Vista, 7, 8, and 10. C:Users<USER>AppDataRoamingAutodeskAutoCAD 20xxRxx.x<LANGUAGE>Support
Windows XP. C:Documents and Settings<USER>Application DataAutodeskAutoCAD 20xxRxx.x<LANGUAGE>Support
For AutoCAD 2009 and earlier, the default location is: C:Program FilesAutodeskAutoCAD 20xxSupport
The AppData and Application Data folders in the above paths are hidden folders (see How to turn on hidden files and folders on Windows).
The default path is specified in the Support File Search Path listed under the Files tab in Options. It is usually the first one shown, pointing to the current user folder.
If there is no longer a .pat file of an existing hatch used in a drawing, use the express tool SUPERHATCH to try and bring in the custom hatch pattern.
