If your pattern contains arcs or circles, use the DIVIDE or MEASURE commands, or use a LISP routine to turn curves into small, connected straight lines.
Explode polylines, regions, and blocks into basic, individual line segments.

The converter fails to find the repeating boundary, making the pattern impossible to tile seamlessly. Key Features of a "Better" Converter If your pattern contains arcs or circles, use

A highly recommended freeware tool by ARKANCE (formerly CAD Studio) that extracts hatch pattern definitions from existing DWG drawings and saves them as standalone .PAT files. They allow you to select objects on your
Many basic converters only handle linear patterns (like lines, dashes, and dots). A handles shapes. It allows you to draw a complex shape (like a hexagonal tile or a stone paver) and instantly generate the code to tile that shape seamlessly.
