Convert CKD to SAT

Understanding CKD and SAT file formats

CKD files are proprietary 2D/3D CAD drawing files created by CAXA, a popular CAD software widely used in China for mechanical and engineering design. These files store detailed design data, including geometry, layers, and annotations.

SAT files are ACIS solid model files developed by Spatial Corporation. The SAT format is a widely supported neutral 3D exchange format used for sharing solid modeling data between different CAD applications.

Why convert CKD to SAT?

Converting CKD to SAT enables interoperability between CAXA and other CAD systems such as AutoCAD, SolidWorks, and Inventor, which support the ACIS SAT format. This is essential for collaboration, manufacturing, and further editing in non-CAXA environments.

How to convert CKD to SAT

Direct conversion from CKD to SAT is not natively supported by most CAD software. The recommended workflow involves exporting the CKD file to a more common format (such as STEP or IGES) using CAXA, then converting that file to SAT using a compatible CAD program.

Step-by-step conversion process

1. Open your CKD file in CAXA (e.g., CAXA CAD or CAXA 3D).
2. Go to File → Export and select STEP or IGES as the export format. Save the file.
3. Open the exported STEP/IGES file in a CAD program that supports SAT export, such as Autodesk AutoCAD or Autodesk Inventor.
4. In the new program, go to File → Export and choose SAT (ACIS) as the output format.
5. Save the resulting SAT file.

Best software for CKD to SAT conversion

• CAXA CAD – For opening and exporting CKD files.
• Autodesk AutoCAD or Inventor – For importing STEP/IGES and exporting SAT files.
• Online CAD converters (such as AnyCAD Exchange) – For direct or intermediate format conversion, if available.

Tips and considerations

• Always check the integrity of the geometry after conversion, as some data may not transfer perfectly.
• Keep backup copies of your original CKD files.
• If you encounter issues, try exporting to both STEP and IGES to see which yields better results in the SAT export.
