Yes, I am a case in point ... I do architectural work as well as landscape architecture. I use Rhino for all my 2d drafting these days. Rhino is a pretty good 3d modeler, too, but I have come to prefer MoI for most modeling as it seems faster and more intuitive for most work. There are a few things it won't do with surfaces that Rhino does well ... so, I shift back and forth between the two as needed. Because of the drafting aspect I do use Rhino more hours of the day most of the time ... modeling (including rendering) takes up to 20% of each project but the other 80% is spent with dimensioned, detailed, drawings and notes ... MoI is not the tool for that.

It would be wonderful if one tool would do it all perfectly ... but one should not try to use a hammer for fine saw cuts.
