Click "Convert." The server will analyze the vectors inside your bounding box. It will then generate a .pat text file. Download this file.
A lightweight, no-frills converter.
Cause: PAT files only support straight line segments. Curves (arcs, circles, splines) must be broken into tiny straight lines.
Solution: In AutoCAD, use the FLATTEN command on 3D curves. For arcs, use the DONUT or BREAK commands. For splines, use SPLINEDIT (Convert to Polyline) and set a high precision (e.g., 0.1 units). dwg to pat file converter online
The server reads your uploaded DWG file. Because DWG is a proprietary format, most online converters rely on open-source libraries (like Open Design Alliance or LibreDWG) to extract vector data. They ignore 3D meshes, raster images, and blocks, focusing only on lines, polylines, arcs, and circles. Click "Convert
Since a direct "one-click" online converter is virtually non-existent due to the complexity of the geometry parsing required, the standard "online" workflow involves two steps: A lightweight, no-frills converter
