As noted by panthony, VW has spent a considerable amount of time (no doubt) working toward a bifurcated model-sheet workflow. However, they just don't seem to get it...
Regress to MiniCAD running in parallel development to early versions of AutoCAD. Complaints from many AEC professionals transitioning from drafting tables was that AutoCAD was too abstract, there was too great a learning curve, unfamiliar territory. Entry MiniCAD. An electronic drafting table with a workflow familiar to drafters. The page was primary.
Then surprise, drafters adopted and co-opted technology, became familiar with a new way of working. An abstracted way of thinking about drawing, their buildings, issuing documents. AutoCAD, with its split MS/PS, becomes comfortable. But it's a hassle managing two distinct and separate sets of data (drawing and annotation).
Meanwhile, development continues on VectorWorks, which sees drafters becoming more CAD abstract-saavy, and acquiesces toward the AutoCAD methodology to implement MS/PS-esque Design and Sheet Layers.
As VectorWorks spends a great amount of effort, mucking the water, grafing on more layer types, viewports, annotations, and places to set scale, AutoCAD managers, users, and standards are returning to a more simplified MS/PS workflow. One that promotes drawing AND annotating in MS while simply printing from PS. Drawings and annotations are now logically re-connected.
And we're left with VectorWorks pushing a half-baked MS/PS variant, and we have no choice but to follow their lead.
Examples:
A. Design Layers and Sheet Layers are both scaled. VW officially recommends that you scale your drawings in both places to help maintain consistent font scaling. Why?
B. VW recommends that dimensions be placed as viewport annotation...thereby eliminating associative dimensioning. Why?
C. How many places can I add dimensions now? In Design Layers, in Annotation, or directly on the Sheet Layer. What is the point of this? There should be a single direct way to dimension a drawing instead of spending time working out the pros/cons of what to annotate.
I don't want VectorWorks to be an AutoCAD clone, and I'm happy to move past MiniCAD. I just want Nemetschek to find an simple 2D drafting and 3D modeling methodology and develop it with some rigor and common sense toward the end user. It all seems a little flaky and reactionary as is.
Enough for now...
