.3DXML File Extension

File created in the proprietary Dassault Systemes 3DXML format; contains meshes, textures, lighting effects, and other 3D object properties; used to specify an XML-based 3D object.

The 3DXML format was created to incorporate 3D information into technical documentation, user manuals, marketing materials, websites, and other software applications.
