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.
Download a trusted version of the GetPat.lsp or MakePat.lsp script from a reputable CAD community site (like CADalyst or CADForum). In AutoCAD, type APPLOAD and press .
If the hatch does not tile cleanly, check your original DWG file. Ensure the linework lines up perfectly on opposite sides of your repeating boundary box. convert dwg to pat file
Excessively detailed DWG shapes with thousands of nodes will create a very heavy PAT file, which can slow down AutoCAD when generating hatches.

Choose your newly created block, click OK, and place it in your drawing area.
Clean your geometry (remove arcs/splines and explode blocks). Move the pattern near the origin . Export as a v2000 DXF file. Draw the individual tile or repeatable unit of
Follow the prompts to set the scale and placement. AutoCAD will treat the DWG block as a repeating pattern directly within the drawing.
If using an AutoLISP routine (like GetPat or Draw2Pat ), type APPLOAD in AutoCAD, select the LSP file, and click Load . In AutoCAD, type APPLOAD and press
