SKP - SketchUp Document is a three-dimensional model developed by SketchUp software. This is a three dimensional design program that is very simple and easy to use. This model allows conceptual images to be created, viewed, and shared quickly and easily.
Models that are generated through SketchUp can be uploaded to Google Earth or shared by utilizing the 3D Warehouse feature. This software program was originally developed by @Last Software; however in 2006 @Last was bought out by Google and added to its extensive list of apps, extensions and programs they offer to the public. @Last developed the first five versions of the program, but Google developed version 6 (the latest version).
