That's not so cut and dry anymore depending on what platform you are using to generate the drawings. The weight is shifting from the drawings to the model. I just spent the last few days setting up views for sheets and the sheets for a meeting today, when I could have been doing modelling and actually made some significant progress to show the client. The sheets meant nothing. The client thought we were behind for "25% DD" (whatever that means), but I digress.
The standard (in my world) 1/8"=1'-0" set of plans is still diagrammatic but the detailing has gotten much more project specific as opposed to standard details.
Instead of saying to the contractor, "Put all this here. It fits. You figure it out." We, at the design level, are putting in all those pieces in a coordinated fashion and showing them an actual model of what it can look like when it's done, in addition to the sheets. The line between designer and contractor is definitely getting more blurrier as expected. There will come a time when our design model can actually be used for fabrication.
