Understanding CTB Files in AutoCAD

CTB files, or Color-dependent Plot Style files, are essential tools in AutoCAD that allow users to manage how colors are applied to layers in a drawing. These files dictate the appearance of printed drawings, enabling specifications for color mapping and printing styles.

1. Access the Application menu.
2. Select Options.
3. In the Options dialog, switch to the Files tab.
4. Expand the Printer Support File Path section.
5. Drill down to Plot Style Table Search Path to view the folder location where your CTB files are saved.
