SKETCH UP

SketchUp is a 3D modeling program designed for professional architects, civil engineers, filmmakers, game developers, and related professions. It is also widely used by teens and pre-teens as an entertainment software. Most people however use it to design buildings to be displayed on Google Earth. It was designed to be more intuitive, flexible, and easier to use than other 3D modeling programs, which often have steep learning *curves.[1] Several features allow designers to "play" with their designs, unlike what is possible in other 3D CAD programs. It is marketed as an easy-to-use conceptual tool with a simple interface. A well known feature in the SketchUp World is the 3D Warehouse. Users can use their Google Accounts to upload models, and then browse the 3D Warehouse for many components and models.
Some of its key features and uses include:
A "smart" drawing cursor (inference) system that allows users to draw 3D objects using a 2D screen and mouse. Simple massing study capability via "push-pull". An interactive Heliodon, or sun angle simulator. Ability to animate camera and sun movements. Models can be individually colored with an assortment of solid colors, textures and materials. Interoperability with Google Earth. Simplicity of use over other modeling programs for children, amateur artists, and hobbyists.
