CAB-i-NET v3.2.0 introduces Sets, a Required Reference Stage Workflow Action, Password Protected Workflow Actions, an Adobe Acrobat Plug-in and a REST API. As well as an array of functionality enhancements. One BS 1192/BIM related application of a Required Reference Stage Workflow Action, is to automatically lock the models which are referenced to a drawing sheet at the point it is sent for checking, enabling a snapshot to be taken of the referenced models and therefore ensuring that the content of the drawing sheet remains unaltered as the models change. Perhaps the biggest game changer however, is the Password Protected Workflow Action. Which delivers dual sign on authentication when approving documents, an emerging requirement of many clients, including Network Rail.
