I like the whole idea of the model changing hands from the designer to the engineer and then finally to the contractor or builder.
Initially the designer would use first the 2D mode to work on overall space layout and then bring it up into the no-framing option to consider all of the architectural elements (ie. trim, windows, doors, siding/cladding etc…) I agree that most architects are generally not overly concerned with stud layouts, holdowns and all of the nuts and bolts that go into a design. They are the big picture guys who are responsible for selling the design, look and feel, and functionality to the customer.
From there the engineer can look into the insertion of additional wall columns and also review the headers, beams, king and trimmer qty. etc… and stud layouts. At this stage something might jump out at him, for example he may determine that a triple top plate is required because of a large truss span, or 2x8 wall studs are required due to the wind loads or wall height or both. The engineer would want to have the full 3D model with framing enabled. He is the nuts and bolts guy when it comes to safety and structural issues.
This is sometime where the engineer and architect clash. I’ve actually had to delete windows out of a design for lateral strength (steel moment frames were too expensive) much to the chagrin of the designer of that job but sometimes practicality overrides ambition and creativity.
The engineer can also enable holdowns/straps (with anchor bolts, threaded rods, coupler nuts) for specified wall panels. He will probably turn off the layers that deal with the look and feel of the building, ie. gypsum, cladding, windows, doors, trim etc…
Then the model gets passed to the contractor who then has the full details of literally every component including the nailing information for every wall panel (that is my goal).
He can quickly pull dimensions or other information from the model as needed and also be able to see exactly what was intended by the designer and engineer.
With the new layout API I am also planning on setting up some automation for wall plan generation and wall framing elevations/details. I haven’t fully defined what the end product will be in this regard but I think some production drawing automation may be useful, especially for prefab wall panel designers/companies.
