| Extension | SKP |

| Format | Binary |
A SKP file is the native file format used by the SketchUp 3D modeling application. The SketchUp application started out in 2000 and has been maintained with newer versions featuring improved features ever since.
Other than SketchUp itself, support for opening SKP files within other 3D model editors is limited. There is a C++ API to help developers integrate the format into their own code and build extensions for SketchUp.
Mesh Geometry
The SketchUp SKP format supports mesh geometry composed of vertices and faces. There is also support for texture coordinates and other advanced 3D content.
SKP Converter Capabilities
As materials containing color information is supported by the SKP format, our tool will do its best to include this in the converted file.

| Format | Text |
An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.
As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.
Mesh Geometry
Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.

As materials containing color information is supported by the SKP and OBJ formats, our tool will do its best to include this in the converted OBJ file.
