The Ultimate Guide to DWG to PAT Converters: How to Create Custom Hatch Patterns for AutoCAD

It does not create a traditional, lightweight .pat file. Instead, it allows you to use an existing DWG block, image, or外部参照 (Xref) as a repeating hatch pattern directly inside your drawing.

If you already have a hatch pattern applied to a shape in your drawing, you can extract its definition. In many Autodesk products, you can open a dialog (like the "Select Hatch Pattern" dialog) and find an Export button. Selecting this allows you to choose one or more patterns and save their definitions to a new PAT file. This is often the quickest method for capturing a pattern you’ve already used.

Depending on your comfort level with CAD and whether you have access to full AutoCAD or a browser, here are the most common conversion methods: How to install custom hatch patterns in AutoCAD - Autodesk

Type the command designated by the script (usually GETPAT or DRAWHATCH ). The Ultimate Guide to DWG to PAT Converters:

A plain text file containing code that defines repeating linear patterns for AutoCAD fills.

A binary file format used for holding 2D/3D design data (lines, arcs, layers).

You draw your repeating tile or pattern in AutoCAD, export it via the plugin, or open the DWG directly in the software. The program automatically calculates the repetition vectors and generates clean PAT code. In many Autodesk products, you can open a

Run the PURGE and AUDIT commands to remove any background metadata that might interfere with the export.

A simple text file (.pat) that contains instructions on how to draw a pattern—line angles, spacing, and dash sequences.

Hatch patterns, stored in .pat files, are vector-based plain text files that define how a specific image or texture repeats across a surface. Unlike a standard DWG drawing, which is a static layout, a PAT file contains mathematical instructions (lineset angles, pen-up/pen-down sequences) that allow a pattern to scale and tile infinitely within a defined boundary.
