Convert CDK to CKD

Understanding CDK and CKD file formats

CDK files are chemical structure files created by ChemDraw, a popular chemical drawing software. These files store molecular structures, reactions, and related chemical information in a proprietary format. CKD files, on the other hand, are used by CADKEY, a CAD (Computer-Aided Design) software, to store 2D and 3D design data. The two formats serve very different purposes: CDK is for chemical data, while CKD is for engineering drawings.

Why convert CDK to CKD?

Converting a CDK file to a CKD file is an uncommon process, as these formats are used in entirely different fields. However, if you need to incorporate chemical structure diagrams into a CAD design, you may want to convert or embed the chemical drawing into a CADKEY project.

How to convert CDK to CKD

There is no direct converter that transforms CDK files to CKD format due to their different purposes. However, you can use a two-step process:

1. Open the CDK file in ChemDraw and export the chemical structure as a vector image (such as DXF or SVG).
2. Import the exported vector file into CADKEY, and then save the project as a CKD file.

Recommended software for conversion

• ChemDraw: Open your CDK file and use File → Export → DXF or File → Export → SVG to create a vector file.
• CADKEY: Import the DXF or SVG file using File → Import, then save your project as a CKD file with File → Save As.

Tips for successful conversion

• Ensure the exported vector file maintains the quality and scale of the original chemical drawing.
• Check compatibility of the DXF or SVG file with your version of CADKEY.
• After importing, adjust the placement and scale as needed within CADKEY before saving as CKD.

Conclusion

While there is no direct CDK to CKD file converter, you can achieve the conversion by exporting your chemical drawing as a vector file and importing it into CADKEY. This method allows you to integrate chemical diagrams into engineering projects efficiently.
