What Is a SAT File in AutoCAD?


When working with AutoCAD, you may come across different file formats that serve specific purposes. One such file format is the SAT file. In this article, we will explore what a SAT file is in AutoCAD and how it is used.

Understanding the SAT File Format

The SAT file format stands for “Standard ACIS Text.” ACIS, which stands for “Advanced Computerized Implementation of Standards,” is a solid modeling interface used by many CAD software, including AutoCAD. The SAT file format is a text-based representation of 3D models created using the ACIS modeling kernel.

Key Features of SAT Files

  • 1. Compatibility: SAT files are widely supported by various CAD software, making them an excellent choice for interoperability.
  • 2.

    Geometry Representation: SAT files store geometric information such as vertices, edges, and faces required to represent 3D models accurately.

  • 3. Solid Modeling: SAT files support solid modeling operations like union, subtraction, and intersection of objects.
  • 4. Data Compression: The text-based nature of the SAT file format allows for efficient data compression without loss of quality.

Using SAT Files in AutoCAD

AutoCAD supports the import and export of SAT files, enabling seamless integration with other CAD applications that use this format. Here are some common use cases for working with SAT files in AutoCAD:

SAT File Import

To import a SAT file into AutoCAD:

  1. Click on the “Insert” tab in the AutoCAD ribbon.
  2. Choose the “Import” option from the “Import” panel.
  3. Select the SAT file you want to import from the file dialog.
  4. Adjust the import settings if necessary.
  5. Click “OK” to import the SAT file into your AutoCAD drawing.

SAT File Export

To export a drawing as a SAT file in AutoCAD:

  1. Navigate to the “Output” tab in the AutoCAD ribbon.
  2. Select the desired objects or entire drawing you wish to export as a SAT file.
  3. Click on the “Export” option in the “Export” panel.
  4. Choose “SAT” as the export format from the available options.
  5. Select a destination folder and provide a name for your SAT file.
  6. Click on “Save” to generate and save your SAT file.


In conclusion, a SAT file is a text-based representation of 3D models used in AutoCAD. It offers compatibility, efficient data compression, and supports solid modeling operations. Whether you need to import or export 3D models, understanding how to work with SAT files can improve your workflow when collaborating with other CAD users.
