In AutoCAD, .PAT files are used to define custom hatch patterns. These patterns are often used to fill enclosed areas in drawings, such as walls or floors.

However, finding the location of .PAT files in AutoCAD can be a bit tricky. In this tutorial, we will guide you through the process of locating these files on your computer.

Locating .PAT Files in AutoCAD

By default, .PAT files are stored in a specific folder within the AutoCAD installation directory. To locate this folder, follow the steps below:

  1. Step 1: Open AutoCAD on your computer.
  2. Step 2: Click on the “Options” button located on the “Manage” tab of the ribbon.
  3. Step 3: In the Options dialog box, select the “Files” tab.
  4. Step 4: Under the “Support File Search Path” section, you will find a list of folders where AutoCAD searches for support files like .PAT files.

In this list of folders, look for a folder named “Support“. This is where .PAT files are typically stored. The full path to this folder may vary depending on your operating system and AutoCAD version.

If you cannot find a “Support” folder in the list, it means that no custom hatch patterns have been defined or added to your AutoCAD installation yet. You can create custom hatch patterns using a text editor and save them with a .PAT extension. Once saved, you can place them in this folder for AutoCAD to recognize them.
