.style

Sketch style that can be applied to a drawing created with Google SketchUp, a 3D modeling program; examples include wavy pencil lines, graphite stick marks, or quick pen strokes; often used to make a CAD model look hand-drawn.

Style files are created with Google's Style Builder, which is included with SketchUp Pro 6 and 7. They may be applied to multiple drawings and can be shared between SketchUp users.

Important: SketchUp, previously owned by Google, is now owned by Trimble.
