What is the file extension SKF?

The SKF file format, which uses ".skf" as file extension, is typically associated with AutoSketch drawing files. AutoSketch is a program developed by Autodesk for creating 2D sketches and vector graphics.

Drawing projects saved under the SKF file format may range from conceptual sketches to floor plans, electrical diagrams and product specifications. SKF is marketed as an entry-level CAD tool for students and professionals who want to create complex, accurate drawings in a simple yet customizable workspace. Although AutoSketch uses SKF as its native file format, drawing projects can also be saved as DWG files, a more popular format that's compatible with several other software for computer-aided design.
