As is known to all, software used for 3D modeling can be found everywhere at present. However, they almost always use their own exclusive file formats, which are incompatible with each other. In order to realize data sharing and exchanging between these 3D software, sometimes, we have to convert the 3D model files generated by different 3D modeling software to our desired formats. This case, a 3D file converter that supports batch processing is necessary.
