Hi Eric, thanks I'm glad that MoI is useful to you for early stage drawing.

That has been a big focus area in MoI to make that stage of things happen fluidly and quickly.

I definitely do intend to have some line types and style in the future, but I'm not quite sure exactly how it will work out yet. It may be something a bit more like an illustration style thing but I will also see about trying to maintain compibility with Rhino for at least some basic stuff.
