The conversion was successful, and a PAT file was created that accurately represents the original design pattern. The resulting PAT file can be used in various design and drafting applications to replicate the pattern.
: An application that converts drawing entities (lines, points) directly into definitions. Hatch Pattern Generators : Tools like those on cadhatch.com
in the command line. Select the existing hatch pattern in your DWG that you want to export. It will automatically generate a separate
Converting a DWG file to a PAT (Hatch Pattern) file is not a standard "Save As" function in AutoCAD, as PAT files require specific line definitions. Depending on whether you are trying to an existing hatch or create a new one from geometry, use one of the methods below. Method 1: Extract Existing Hatches (LISP Routine) convert dwg to pat file
Use your cursor to select all the vector elements that form your repeating pattern.
A .PAT file is essentially a text-based set of coordinates and instructions that tell AutoCAD how to repeat lines to form a pattern. Because hatch patterns are mathematical repetitions, they can only be created from simple linear geometry.
Browse to the LISP file, click , and close the dialog box. The conversion was successful, and a PAT file
Click inside the bounded area you wish to fill, then press . Pros & Cons:
Is your geometry made of or complex curves and shapes ?
Draw the individual tile or repeatable unit of your pattern in a new DWG file. Keep the geometry clean, using only basic lines and arcs. Hatch Pattern Generators : Tools like those on cadhatch
: A professional-grade standalone editor that can import DXF/DWG and export a formatted .pat file.
Type the command designated by the script (usually GETPAT or MKPAT ).
