Convert CDW to another file type
To convert CDW drawings to another format, you need KOMPAS-3D or other Cad software.
Convert a file to CDW
To convert other file formats to the "2D CAD Drawing" file type, you need software like KOMPAS-3D or a similar tool.
About CDW files
The .cdw file is a proprietary 2D CAD drawing format created by KOMPAS-3D, a prominent mechanical design and engineering software developed by the ASCON Group. These files are typically used to store highly detailed 2D drafts, schematics, and technical illustrations for manufacturing and architecture.
While KOMPAS-3D is powerful, the .cdw format is highly proprietary and notoriously closed. Users frequently encounter severe limitations when trying to share these files because standard industry programs like AutoCAD or SolidWorks cannot natively open them. Furthermore, opening a .cdw file usually requires an expensive subscription or a heavy desktop installation of the ASCON software suite. As a result, users desperately need to convert .cdw files to standard industry formats like DWG, DXF, or PDF for seamless collaboration.
Because this file format is heavily guarded, it is difficult to open or convert online. Typical online CAD converters fail because they lack the proprietary ASCON rendering engine required to accurately interpret the geometry. Often, only the original software can properly read or export the exact CAD data. However, under the hood, modern .cdw files are structured as ZIP containers. We can identify the file format, inspect the internal ZIP structure, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your CDW file, detects the exact format, and lets you read the text inside.
If you want to convert CDW file to PDF, DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT or X_T, you can use KOMPAS-3D or similar software from the "2D CAD Drafting" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to CDW, try KOMPAS-3D or another comparable tool in the "2D CAD Drafting" category.
The CDW Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CDW converter.
