Steps to Load a CTB File in AutoCAD 2018
Loading a CTB (Color Table) file in AutoCAD enables you to manage how colors are printed in your design. Here’s a step-by-step guide to help you load a CTB file effectively in AutoCAD 2018.
Step 1: Open Your Drawing
Begin by launching AutoCAD and opening the drawing file you wish to work with. Open the file by navigating to "File" and selecting "Open." Locate your drawing and click "Open."
Step 2: Access the Page Setup
Once your drawing is open, direct your attention to the Layout tab that you intend to set up. Right-click on the Layout tab (located at the bottom of the screen) and select “Page Setup Manager” from the context menu. This action will open the Page Setup Manager dialog.
Step 3: Modify Page Setup
In the Page Setup Manager, you’ll find a list of existing page setups. Highlight the setup you want to modify and click the “Modify” button. This process will lead you to the Page Setup dialog where various settings can be adjusted.
Step 4: Choose the Plot Style Table
Within the Page Setup dialog, locate the "Plot Style Table (pen assignments)” dropdown menu. Click on it, and you will see a list of available plot style tables. Find and select your desired CTB file from this list. If you don’t see it, ensure that the CTB file is saved in the correct directory that AutoCAD accesses.
Step 5: Confirm Plot Style Selection
After selecting the appropriate CTB file, ensure that the "Plot with plot styles" checkbox is enabled. This setting will allow the CTB file to control the printing properties for your layout.
Step 6: Save the Configuration
Once you’ve made all the required changes, click “OK” to save the settings in the Page Setup dialog. This brings you back to the Page Setup Manager. Here, you can see your modified settings listed.
Step 7: Close and Print
After setting the CTB file, close the Page Setup Manager. To print your drawing using the newly configured plot style, go to "File" and select “Print” or use the shortcut “Ctrl + P.” Review any additional print settings and click “OK” to proceed with printing.
How to Ensure CTB Files are Accessible
If your desired CTB file does not appear in the list during step 4, check the following:
-
CTB File Location: Ensure the CTB files are saved in the correct directory. You can find this by going to Tools > Options, then navigating to the Files tab and checking the "Plot Style Table Search Path."
-
File Compatibility: Confirm that the CTB file is compatible with AutoCAD 2018. Older CTB files may require conversion or modification to function correctly.
- Refresh AutoCAD: Sometimes restarting AutoCAD can refresh the application’s file access, ensuring that new or modified CTB files appear in the list.
