I would like to add my support for native dimensioning and notation. No disrespect for Max's script which has been very helpful, but MOI deserves a fully integrated approach to communicating with clients. For me, that means a robust and flexible notation environment that can be exported to Illustrator as editable paths without a clunky background image. I realize that a background image may be needed to support model shading but I would like to see MOI's notation capabilities implemented in the same manner as its curves. For me, the most significant improvements in MOI will be those that help me communicate with my clients and production teams. And... by the way... thanks for this software.
