US Patent 9454623 Social computer-aided engineering design projects

In one embodiment of the present disclosure, the capabilities of a social collaboration application are leveraged to permit synchronized viewing of computer aided design (CAD) models and exchange of annotations (e.g., redlines) related thereto, in a social review session involving differing applications executing on different computers. By utilizing the capabilities of the social collaboration application as a transport mechanism, users operating differing applications on different computers may participate in the social review session for the CAD model, thereby allowing users who do not, for example, have access to the application in which the CAD model was developed to be part of the review process.
