Extract text from CADdy drawings (TDW)
To convert TDW drawings to another format, you need CADdy or other Cad software.
To convert other file formats to the "Electrical CAD Drawing" file type, you need software like CADdy or a similar tool.
The .TDW file extension is most commonly an Electrical CAD Drawing associated with CADdy or Caddy++. It is also frequently utilized to store Civil Engineering Survey Data for 3D-Win, electrical engineering drawings for EPLAN 5, and controller function data for Technische Alternative Tapps (where it functions under the hood as an XML file).
Because the .TDW extension is shared by completely distinct engineering applications, these files are extremely fragmented and highly proprietary. A .TDW file created for a survey in 3D-Win will immediately fail if opened in CADdy. Furthermore, none of these formats are natively supported by modern web browsers or standard operating systems like Windows or macOS. Relying on legacy software like EPLAN 5 or purchasing expensive, specialized engineering suites just to view a single file is impractical, time-consuming, and costly.
To make these files accessible, conversion is strictly necessary. For electrical CAD drawings and templates, convert your file to DXF or DWG to restore compatibility with industry-standard vector tools like AutoCAD. If your goal is sharing with non-technical clients, convert to PDF for simple viewing and printing. If the file contains 3D-Win survey data, extracting it to CSV is the most pragmatic approach for data analysis.
Convert.Guru analyzes your TDW file, detects the exact format, and lets you read the text inside.
Users also converted TWD, EPJ, E2 and EOX files.

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 TDW converter.
