What Is STB in AutoCAD?

If you have been using AutoCAD for any length of time, you may have come across the term STB. So, what exactly is STB in AutoCAD? In this article, we will explore the meaning and significance of STB in AutoCAD.

Understanding STB

STB stands for Style Table (Binary). It is a file format used in AutoCAD to define the appearance of objects such as layers, linetypes, text styles, and dimension styles. The purpose of using an STB file is to separate the style information from the drawing itself.

The Difference Between CTB and STB

CTB (Color Table) and STB are two file formats used in AutoCAD to define plotting properties. The key difference between them lies in how they manage color settings.

  • CTB: Short for Color-Dependent Plot Style Table, CTBs are based on colors. Each color has a specific plot style assigned to it.

    When plotting with CTBs, you need to associate each color with a suitable plot style.

  • STB: In contrast, Style Table (Binary) files do not rely on colors. Instead, they use named plot styles that are independent of colors. With an STB file, you can easily change the appearance of all objects assigned to a particular named plot style without affecting their colors.

The Advantages of Using STBs

Using STBs can offer several advantages over CTBs:

  • Flexibility: By decoupling object appearance from color assignments, STBs provide more flexibility in managing plotting styles. You can easily modify the appearance of multiple objects by simply changing the properties of their assigned named plot style.
  • Consistency: STBs allow you to maintain consistent plotting styles throughout your drawings.

    By using named plot styles, you can ensure that all objects with the same plot style will appear consistently, regardless of their colors.

  • Ease of Use: With STBs, it is easier to create and manage custom plot styles. You can define and customize your own named plot styles based on specific requirements, making it simpler to achieve the desired visual output.

Using STB Files in AutoCAD

To use an STB file in AutoCAD:

  1. Open AutoCAD and navigate to the “Plot” or “Page Setup Manager” dialog box.
  2. Select a layout or a drawing sheet.
  3. In the Plot Style Table (Pen Assignments) section, choose “Add or Edit Plot Styles.”
  4. In the Plot Style Table Editor dialog box, click on “New” to create a new named plot style or select an existing one to modify.
  5. Adjust the properties of the selected named plot style according to your preferences.
  6. Save your changes and apply the STB file to your drawing or layout as needed.

Note: When using STBs, it is essential to properly manage and distribute them along with your drawings. Otherwise, if an STB file is missing or not properly referenced, it may result in unexpected plotting results.

In Conclusion

In summary, STB files offer a streamlined approach to managing plotting styles in AutoCAD. By using named plot styles instead of color-dependent assignments, you can achieve greater flexibility, consistency, and ease of use in defining the appearance of objects. Understanding STB files and their advantages can greatly enhance your AutoCAD workflow and improve the visual presentation of your drawings.
