DWG to PDF in Python: Convert AutoCAD Drawings

DWG is the native drawing format of AutoCAD. A single file can hold the full geometry of a building or a part, arranged in layers, blocks and dimensions, at a level of detail that only CAD software reads correctly.

Most people who receive a drawing have no CAD seat. A PDF keeps the lines as vectors, prints at the right scale and opens in any reader, which is why drawings are circulated as PDF for review, for approval and for site copies.

GroupDocs.Conversion Cloud does the conversion over REST, so nothing from Autodesk has to be installed. Pass the DWG file, ask for PDF, and the result comes back. A page range narrows the output, and the PDF can be watermarked or given a password.

The Python SDK handles the requests and the authentication, which needs only a Client ID and Secret, so a batch of drawings becomes a loop over a directory. A free web converter and the API Explorer cover single files and quick tests.
