Convert PRT to CKD

Understanding prt and ckd file formats

PRT files are part files commonly used by CAD (Computer-Aided Design) software such as Siemens NX, PTC Creo, and SolidWorks. These files store 3D models, assemblies, and design data for engineering and manufacturing purposes.

CKD files are the native CAD data files for KeyCreator (formerly known as CADKEY). CKD files contain 2D and 3D design data, including geometry, layers, and attributes, used for mechanical design and drafting.

How to convert prt to ckd

Direct conversion from PRT to CKD is not always straightforward, as these formats are proprietary and used by different CAD systems. The most reliable method is to use an intermediate neutral format such as STEP (.stp, .step) or IGES (.igs, .iges), which are widely supported by most CAD software.

Step-by-step conversion process

1. Open your PRT file in its native CAD software (e.g., Siemens NX, PTC Creo).
2. Export the file to a neutral format:
   • Go to File → Export → STEP or File → Export → IGES.
   • Save the exported file to your computer.
3. Open KeyCreator.
4. Import the neutral file:
   • Go to File → Import → STEP or File → Import → IGES.
   • Select the exported file and open it.
5. Save the imported design as a CKD file:
   • Go to File → Save As and choose the CKD format.

Best software for prt to ckd conversion

• KeyCreator – The native software for CKD files, supports importing STEP and IGES files.
• Siemens NX or PTC Creo – Use these to export PRT files to neutral formats.
• Autodesk Fusion 360 – Can open PRT files and export to STEP/IGES for further conversion.

Tips for successful conversion

• Always check the imported geometry in KeyCreator for accuracy.
• Some features or parametric data may not transfer perfectly; manual adjustments may be needed.
• Keep backup copies of your original files before conversion.
