A .STB file is a AutoCAD Plot Style Table File, created by Autodesk.

Open with Autodesk AutoCAD 2023. Available for Windows.

What is a .STB file?

The file extension .STB stands for an AutoCAD Plot Style Table File. This type of file is used with AutoCAD, which is a software application used for creating both 2D and 3D drawings and designs. An .STB file contains plot styles, which are instructions on how to display colors and line weights on different objects in a drawing. These files store various settings such as color, whether to show in dither (a type of texture), grayscale (shades of gray), pen number (which pen to use in a plotter), line weight (thickness of lines), fill style (pattern inside shapes), and styles for the beginnings and ends of lines. These settings help in making sure that the design objects in AutoCAD drawings look consistent when printed or viewed on different devices.

.STB files are particularly useful because they allow designers to apply a set of display properties to objects in a design, which can be reused across multiple projects. This makes it easier to maintain a consistent look in all drawings.

The .STB files were created as a way to move away from older color-based layer styles (stored in .CTB files) to more flexible object-based property styles. This change allows for more versatility and easier sharing of designs because the style settings are tied to objects rather than layers, which can vary between projects.

To open an .STB file, you would typically use Autodesk AutoCAD 2023, which is the latest version of the AutoCAD software. This program supports the .STB file format and can utilize the plot styles defined within it for drawing and plotting tasks.

If you have older .CTB files (which are based on color layers), AutoCAD also provides a way to convert these into the newer .STB format, allowing you to take advantage of the more advanced object-based styling system in your existing projects.
