Extract text from AutoCAD plot styles (CTB)
To convert CTB plot styles to another format, you need AutoCAD or other Settings software.
To convert other file formats to the "Plot Style Table" file type, you need software like AutoCAD or a similar tool.
The .CTB file extension primarily represents an AutoCAD Color-Dependent Plot Style Table. This settings file is used by CAD software like AutoCAD to control how drawing colors translate to physical printed output. It dictates line weights, styles, and patterns based on the original object colors. Alternatively, the extension is used by CherryTree for encrypted hierarchical notes (stored as a SQLite database) and by ChiTuBox for sliced 3D models prepared for resin 3D printers.
The main disadvantage of .CTB files is their highly proprietary and application-specific nature. AutoCAD plot styles cannot be easily interpreted without CAD software, making them useless to non-technical stakeholders who just need a viewable design. Sharing CAD files without their accompanying .CTB file often causes printing errors and missing line weights. For CherryTree users, viewing an encrypted note without the exact software installed is impossible. For 3D printing, a sliced .CTB file is locked to specific resin printer settings and cannot be easily reverse-engineered back into an editable 3D mesh.
Converting .CTB files solves these accessibility problems. Drop your file here to view and convert it securely right in your browser. For AutoCAD environments, you can convert legacy .CTB files to the newer STB (Named Plot Style) format for modern, object-based printing. For CherryTree databases, converting your notes to PDF or TXT ensures the text is readable on any device. For ChiTuBox files, extracting the layer slices to ZIP or generating a PDF summary report is ideal for archiving and documentation.
Convert.Guru analyzes your CTB file, detects the exact format, and lets you read the text inside.
Users also converted PC3, STB, CBT, CHITUBOX, STL, CTP, GOO, CBDDLP, XCTB, PCP, ZIP, DWG and CTB2 files.
If you want to convert CTB file to STB, STL, CFG, PDF, GO, PCP, DWG, INI, CONF, CONFIG, JSON or XML, you can use AutoCAD or similar software from the "Plot Style Configuration" category. In the File menu, look for Save As… or Export….
To convert ZSHRC, CONF, RCFILE, GITCONFIG, RC, PLIST, BASHRC, CONFIG, PROFILE, INI, PREFS or CFG files to CTB, try AutoCAD or another comparable tool in the "Plot Style Configuration" category.
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 CTB converter.
