Penguin
Penguin brings freehand sketching, watercolor painting, cartoon-like rendering and technical illustration to Rhino and AutoCAD. Penguin is a conceptual, sketch and cartoon, non-photometric scan line renderer. With Penguin you can create stylized images of your models with an artistic look for enhanced graphic and visual appeal. Penguin 2.0 runs inside Rhino and has the same hardware requirements. Rhino with Penguin runs on ordinary Windows desktop and laptop computers. No special hardware is needed beyond what is required for AutoCAD. Penguin 2.0 is completely integrated with Rhino. All of its configuration dialogs can be accessed as any other Rhino dialog would be, inside Rhino properties or object properties. The dockable object properties panel updates while other commands run or while changing the selection. Penguin 2.0 supports any Rhino native object, including 2D objects like dimensions or curves. You can define specific settings for those objects like any other object.
