What is a DN File Type?
DN files are working files, meaning that they can be modified in Dimension, saved, closed and then reopened in Dimension to be edited. Only Dimension supports files. Therefore, they are shared, they should only be with other users of Dimension. Users can, however, export DN files in Dimension to more widely supported formats, such as .PNG and .OBJ, so that they can be opened by d' other programs.

To convert to another format in Adobe Dimension, select File → Export or select Render view. Certain formats you can export the file format to include .GLTF, .GLB, OBJ, PNG and .PSD.
