Workbench 3.1 was released in July 2021. The 3.1 release includes support for integration of a digital edition with a 3D model of the inscribed item. The feature supports implementation of bi-directional synthesis at an akṣara level. When published via Workbench Reader Toolbar a researcher can select an individual syllable or entire word in the edition and the 3D viewer will respond by rotating the 3D model, adjusting the camera angle and display an annotation with the transliteration and translation. The integration works in reverse as well: the researcher might select an annotation on the 3D model and the edition and 2D image viewer will respond.
