When working with AutoCAD, you may come across CTB files. But where exactly do these files go? In this article, we will explore the location of CTB files in AutoCAD and how they are used.
What are CTB Files?
CTB stands for Color-Based Plot Style Table. These files contain information about how AutoCAD should plot or print objects in different colors. In other words, a CTB file determines the line weight, line type, and color of plotted objects.
Where to Find CTB Files?
In AutoCAD, CTB files are typically stored in a specific directory known as the “Plot Styles” folder. The location of this folder may vary depending on your operating system and the version of AutoCAD you are using.
To locate the Plot Styles folder in AutoCAD:
- Step 1: Open AutoCAD and navigate to the “Options” dialog box. You can access it by typing “OPTIONS” in the command line and pressing Enter.
- Step 2: In the Options dialog box, select the “Files” tab.
- Step 3: Look for the “Printer Support File Path” section and click on the “Plot Style Table Search Path” button next to it.
A new dialog box will appear displaying a list of directories where AutoCAD searches for plot style files. This list includes both system-defined paths and user-defined paths.
User-Defined Paths
If you have created custom CTB files or downloaded them from external sources, it is recommended to store them in a user-defined path. This way, you can easily manage and access them when needed.
To add a user-defined path:
- Step 1: In the Plot Style Table Search Path dialog box, click on the “Add” button.
- Step 2: Browse to the directory where your CTB files are located.
- Step 3: Click “OK” to save the changes.
System-Defined Paths
The system-defined paths in AutoCAD contain default CTB files that come pre-installed with the software. These files are essential for plotting objects with different line weights and colors.
By default, AutoCAD looks for CTB files in the following system-defined paths:
- C:\Program Files\Autodesk\AutoCAD \Support\Plot Styles
- C:\Users\%username%\AppData\Roaming\Autodesk\AutoCAD \Rxx.x\enu\Support
Note: Replace “Rxx.x” with the version number of AutoCAD you are using. For example, R23.1 for AutoCAD 2023.
Selecting a CTB File in AutoCAD
Once you have stored your CTB files in either a system-defined or user-defined path, you can easily select them within AutoCAD for plotting purposes.
To select a CTB file:
- Step 1: Open the “Plot” dialog box by typing “PLOT” in the command line and pressing Enter.
- Step 2: In the Plot dialog box, locate the “Plot Style Table (Pen Assignments)” section.
- Step 3: Click on the drop-down menu and select the desired CTB file.
By choosing a specific CTB file, you can control how AutoCAD plots or prints your drawings with different line weights, line types, and colors.
In Conclusion
CTB files play a vital role in defining plot styles in AutoCAD. By understanding where these files are located and how to select them, you can efficiently manage your plotting settings and achieve desired output results. Remember to store custom CTB files in user-defined paths for easy access and organization.
Now that you know where CTB files go in AutoCAD, you can confidently make use of them to enhance your plotting experience!
