Just a mention about MoI on the Rhino forum a few years ago. I would love to use MoI exclusively and when dimensions and line widths come to MoI that is exactly what I will do. MoI and Octane will be all I need. Just waiting for the day.
Now most of my design work happens in MoI but when I have to start dimensions I am forced to switch back and forth, with regret. MoI is so fluid ... I love it.
