What is SKP file?

File with SKP extension contains 3D model or element of such model. This file format is native to SketchUP software tool. SKP is a proprietary binary format, and as such its documentation was never released to the public. However, SKP libraries are available to the public. Each model stored in SKP file holds information about:

  • Points,
  • Edges and edge effects,
  • Shading,
  • Textures.

SKP files can be used as file containers to store separate models as components of a larger project. SketchUP was developed by @Last Software in 2000. The company was then bought by Google in 2006. SketchUP was conceived as a general-purpose 3D modeling software application for commercial use, but it soon was embraced by professionals working in the fields of architecture, interior design, engineering, or game development. SKP models can be used by Google Earth application, thanks to Google engineers. Since 2012 SketchUP belongs to Trimble Inc. Various SketchUP editions include:

  • Pro – version for professional users that offers additional functions and plugins, including option to store projects in various 3D formats,
  • Shop – web-based version for creators of real-life projects,
  • Free – free web version available since the end of 2017; limited functionality,
  • Make – released in 2017 as a free desktop version.

SKP file stucture depends on what application was it generated with. Creating, viewing, and editing of SKP files is available through SketchUP C API library and tool called SketchUP Importer/Exporter. Files that contains backup copy of SKP project use the SKB extension. SketchUP developer also released a 3D project library Warehouse 3D, where users can share their designs.
