To ensure your custom hatch tiles perfectly without gaps or overlapping lines, follow this standard design workflow. Step 1: Set Up a Unit Square
: Ensure your design is composed only of Lines or Polylines . Patterns do not natively support arcs or splines.
Contains vector geometry, layers, and metadata. dwg to pat converter
Open your converter tool, select your cleaned geometry, define the pattern name, and export the file. How to Install and Use Your New PAT File in AutoCAD
: Utilities like PatOut from CAD Forum allow users to extract existing hatch patterns directly from a DWG into separate PAT files for reuse. To ensure your custom hatch tiles perfectly without
For decades, the CAD community has relied on custom LISP routines.
Move the geometry near the origin (coordinates 0,0) to prevent alignment errors. Export the selection as a file (ideally version 2000). Contains vector geometry, layers, and metadata
If you don't want to deal with .PAT files at all, you can use the Superhatch tool included in AutoCAD's Express Tools How it works : You turn your drawing into a , then run the SUPERHATCH
