Dwg To Pat Converter -

Built directly into AutoCAD; no installation required.

Converting a (drawing) file into a (hatch pattern) file is a common task for CAD users who want to turn custom geometry into reusable textures. While there isn't a single "one-click" native button in AutoCAD for this, the process generally involves simplifying your geometry and using an intermediary format or a specialized tool.

To ensure your custom hatch tiles perfectly without gaps or overlapping lines, follow this standard design workflow. Step 1: Set Up a Unit Square dwg to pat converter

But what if you could just draw your pattern? 📐

The DWG is the default file format for AutoCAD drawings. Converting a portion of a drawing—like a custom tile, a unique flooring pattern, or a company logo—into a PAT file is a powerful workflow for several reasons:

If you don't want to use third-party software, follow this standard workflow to prepare your geometry: 1. Simplify Your Geometry Use Lines Only Built directly into AutoCAD; no installation required

: Patterns can only contain straight segments; convert all arcs or splines into small line segments. Explode Blocks

Using a plugin inside AutoCAD is the most reliable method because it preserves the exact scale and geometry of your drawing.

A PAT (pattern) file, conversely, is a specialized, plain-text ASCII file used to define custom hatch or fill patterns. A PAT file doesn't contain graphic coordinates in the traditional sense but instead provides a specific definition —written in a simple, code-like syntax—that describes the geometry of a pattern that can be tiled and repeated across a surface. Because of this complexity, a direct conversion from a complex DWG drawing to a PAT definition is not a straightforward, automated process. It generally involves either manually writing the definition or using specialized tools to extract and translate the vector geometry into a tiling pattern. How to Convert DWG Geometry to a PAT

For users who do not want to use external tools, the AUGI Forums describe a manual approach involving exporting views.

Web-based tools are emerging that allow you to upload a DWG or DXF and download a PAT file.
