- The Asset-Importer-Lib - Open Asset Import Library (short name: Assimp) is a portable Open Source library to import various well-known 3D model formats in a uniform manner. The most recent version also knows how to export 3d files and is therefore suitable as a general-purpose 3D model converter.
 - OpenFBX - Lightweight open source FBX importer
 - FBX - C++ Library for reading and writing FBX files
 - fbx - Single-file binary FBX importer.
 - StepCode - STEPcode (formerly NIST's STEP Class Library) is used with IFC, STEP, and other standards that utilize the technologies of ISO10303 (STEP). It generates C++ and Python from EXPRESS (10303-11) schemas. The code is capable of reading and writing STEP Part 21 exchange files. It also utilizes Parts 22 and 23 (SDAI and its C++ binding). http://stepcode.org

- Clone from this repository
 - Prepare a branch with your model in it. Place the model at the model-bd, select the name of the format in the folder and create another folder with the name of your model. If you want o share some special information abou the model add a readme-file.
 - Create a pull-request
 - The pull-request will be reviewed and merged afterwards. We will add your name to the list of contributors.
