@ivelin.peychev and @MattE You raise a great points that different disciplines have different needs. Examples are shop drawings, technical illustration, various engineering and construction drawings, etc.
I think the focus, at least initially, would be on the lowest common denominator and trying to provide a complete solution for the simplest applications. My guess is this would be shop drawings and technical illustration.
From a developers point of view I want to be able to make the 2-d drawing from the 3d Rhino model. A general Rhino model has no information about architectural or engineering features like door, walls, ship hulls, conduit etc. So any special drawing consideration that depends on application specific information is too complicated for me.
The input information we have is: object geometry; view specification and object properties like layer and color. On the output side we produce curves, and probably hatches (filled planar regions) with attributes e.g, color, transparency, line type, hatch patterns, etc.
It is my hope that even with this restricted approach we could still solve important problems for a significant set of users. Note that in Rhino both Make2d and technical display operate within this context, with no application specific information.
