The files have a .sldprt extension. Only the final solid model is imported. Geometry, curves, and construction history are not imported. This means that you only get a single solid and not the individual design features from SolidWorks.
SolidWorks configurations are also supported. If there are multiple configurations, the SolidWorks Configurations dialog is displayed. Select which configuration you want to import and click OK.
Tip: If you import a .sldprt or .sldasm file into FeatureCAM, colors are not honored. To keep colors, export an .X_T file from SolidWorks and import that file into FeatureCAM.
