OBJ Export for SolidWorks is a WavefrontВ® OBJ file export add-in for SolidWorksВ®. This add-in gives SolidWorks the ability to export 3D solid and surface data from a SolidWorks part and assembly document to meshes in an OBJ file.OBJ Export for SolidWorks tessellates the solid bodies in a SolidWorks part or assembly document into individual triangular meshes. These meshes are then exported to an OBJ file as mesh objects.
