CKD File - opening and understanding

Did your computer fail to open a CKD file? We explain what they are used for and recommend software that we know can open or otherwise handle your .CKD files.

What is a CKD file?

A .CKD file is a Cadkey Design file. These CKD files contain the 2D and 3D designs created in Cadkey, a 2D/3D mechanical CAD (Computer-Aided Design) software. With CKD files, you can manage your CAD data, and you don't have to stick to one strategy. You can have separate files for different parts of your assembly, meaning you can revise each part/section individually.
