: Import and test your new PAT file in your target CAD program to ensure it looks and behaves as expected.
: Place the file in the Support File Search Path (found in Options > Files ).
Export the final file directly as an AutoCAD or Revit compatible file. MakePat (AutoCAD Express Tools)
: Use a dedicated utility or online tool to translate the vector data into the PAT text format. Autodesk Community, Autodesk Forums, Autodesk Forum Tools and Software dxf to pat
This is a simple, plain-text file containing code that defines repeating line patterns. Hatch patterns do not store actual shapes; they store mathematical instructions (angle, origin-x, origin-y, delta-x, delta-y, dash, space) to infinitely repeat lines.

Save or export your drawing. Choose an older DXF format (like AutoCAD R12/LT2 DXF) if you are using legacy conversion tools, as newer DXF versions contain complex data structures that simple converters cannot read. Top Tools for Converting DXF to PAT
Draw your custom tile exactly how you want it using familiar CAD tools. : Import and test your new PAT file
Hatch patterns strictly support straight line segments. All circles, arcs, and splines in your DXF must be deleted or traced over/tessellated into small, straight polyline segments. Simplification is Key: High-fidelity shapes result in massive, slow-loading
Developed by Autodesk, this is a tagged data representation of all the information contained in an AutoCAD drawing file. It supports complex geometries including arcs, splines, text, and 3D meshes. .PAT (Hatch Pattern File):
HatchKit is particularly effective because it can extract pattern definitions from a DXF, a process that is otherwise very difficult to do manually. MakePat (AutoCAD Express Tools) : Use a dedicated
Open a trusted online conversion platform (such as CloudConvert, Convertio, or specialized CAD utilities). Select the Output: Choose PAT as your target output format.
Navigate to a trusted online file conversion portal (such as Vectorizer or dedicated CAD converter sites). Upload your file. Select PAT as the target output format. Click Convert and download the resulting file.
: The user saves this isolated geometry as a DXF file —often using an older version like "2000 DXF" to maximize compatibility with conversion tools [2].
