This add-in will enable you to export a 3D model as a Wavefront OBJ (.obj) file in a very simple and efficient way. 

The OBJ file is generated from user-specified "bodies" of a 3D model. You have the option to export ALL "bodies", ALL "visible bodies" or just user-selected "bodies". There are quality options consisting of "Best", "Low", "Normal", "High" and "Very High". You also have the option to modify the output scale (default scale of 1.0), the option to include "normals" and the option to export the material template library (.mtl) file. You can quickly export using the right-click context menu that will export the model using the previously used settings.
