This 3D model was originally created with Sketchup and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 I made a maquette on school of wood( it is not really finished...) so i made it in sketchup you need a NASA computer to view it normally with shadows on ( a extremely fast computer should work too.)
