opening creo-saved files in solidworks

I dont think there is an option in SolidWorks to open native CREO Direct files (.pkg). I believe there is a module in the CREO Data Interfaces to add SolidWorks. With this module you can export CREO Direct files as .parasolid files. There are also the options to export as .step or .iges, but parasolid will translate more efficiently.

Hope this helps.
