You will now see your custom hatch patterns at the bottom of this list: I use plain Notepad to make sure that the *CLG_GYP (red box) matches the filename and this cannot have spaces, the description following can have spaces

In the example, the pattern file created is called CLG_GYP.PAT Create each hatch patter separately, or if you have one combined, you will need to separate them all out into separate files.I will be using D:\Hatch Patterns as my example Best place to start is to create a hatch pattern folder (to make it easier for future upgrades).The end of the pattern file must be a blank line.The PAT file name must exactly match the name of the pattern.Each hatch pattern should be in its own file.Issue: You have custom hatch patterns given to you or created by you and need to know the best way to add them into AutoCAD so you can use them
