Bentley Redline allows design reviewers to view and make comments on MicroStation,
AutoCAD or hybrid engineering project data, enhancing project collaboration and
communication. It combines easy-to-use mark-up tools with the viewing capabilities
of Bentley View, making it the ideal tool for a project participant who needs
to contribute to the design process. Either MicroStation or AutoCAD users can
then easily integrate these mark-ups into designs.

Bentley Redline supports both printing to scale and VBA.
