Blackboard’s assignment inline grading functionality is serviced by a third party tool called Crocodoc. This tool allows faculty to annotate assignments with text and point based comments, highlighting and drawing directly within the course site. The Crocodoc service is being retired by Box, the company who owns Crocodoc. Box is replacing with a comparable service called New Box View.
On December 22, 2017, Box View will replace Crocodoc, after which you will begin to use the New Box View interface.
