SolidWorks technical tips - export to CADKEY Classic
How do I export files to CADKEY Classic?
CADKEY "Classic" does not support solid models, but you can extract the wireframe boundaries from a SolidWorks file for export via IGES. Choose File > Save As > IGES, and click the Options button. Configure the IGES export options from SolidWorks to output 3D wireframe curves as Parametric splines (not B-Splines).
