.SKF File Extension
What is an SKF file?
An SKF file is a CAD drawing created by AutoSketch, a CAD program used for creating 2D conceptual sketches and other technical drawings. SKF files can only be created and opened by AutoSketch, but can be converted to the .DWG format in the software.
NOTE: AutoSketch was discontinued after the release of version 10 in November 2008.
