The Export UDBapp File option in the file menu will create a copy of the currently open drill as a .3dudb file type. These .3dudb file types, also known as UDBapp files, can be viewed in the UDBapp.
To create a UDBapp file, first open the drill from the File menu. Once the drill is open, go to the File menu and choose Export File then Export UDBapp File. A new window will open where you are prompted to sign in with your UDBapp Ensemble Code and Password. Once entered, you’ll be able to upload the UDBapp file to the UDB servers.
