What it does

This policy setting allows you to specify a list of 3D model file formats that will be blocked from being loaded in Office applications. If you enable this policy setting, you can specify a list of 3D Model file format that Office applications will block on insert or load. You should specify the list of 3D model file formats to block in a list of files extensions. For example, to block the FBX extension, enter the string “FBX”. To block the FBX and OBJ extensions, enter the string “FBX; OBJ”. If you disable or do not configure this policy setting, Office applications do not restrict any 3D model file formats.
