STYLE is a file extension associated with a 3D modeling software called SketchUp. STYLE is a STYLE file in which, for example, sketching parameters are defined in the program. Often this solution is used to imitate a manual sketch in a project.

STYLE files can be created by the user in the included tool called Google Style Builder. SketchUp was developed by Google, but is currently being developed by a second owner, Trimble.
