Which building information is best conveyed in 3D, and which still requires 2D?
◦ Which stakeholders need 2D drawings, and why has that not gone away?
Contractors, engineers, and code officials still need 2D drawings because they provide exact dimensions, technical details, and annotations that are difficult to see clearly in 3D.
◦ Give an example of something in your building a 3D view fails to communicate.
In my apartment design, the 3D view shows the overall layout, but it doesn't clearly communicate door clearances, room dimensions, or the exact locations of plumbing fixtures.
The same location needs to be shown differently to different audiences.
◦ How would information at one spot be filtered for a client, a contractor, a code official and a fabricator?
For my apartment kitchen, I would show the client a simple 3D view, the contractor a dimensioned plan, the code official the required clearances, and the fabricator detailed cabinet dimensions and materials.
◦ What is the risk of showing everyone the same view?
Some people might get overwhelmed by unnecessary details, while others might miss important information needed for their work.
View templates enforce consistency across a set.
◦ What goes wrong on a real project when views are configured individually?
Drawings can end up with inconsistent line weights, visibility settings, and annotations. This can confuse people and make coordination more difficult.
◦ Who should own the templates and standards, and why?
I think the BIM manager or project lead should manage them, with input from the design team, to make sure everyone follows the same standards and the drawings remain consistent.
Your schedules pull information straight out of the model.
◦ How can schedules support procurement and model based estimating?
◦ What is the danger of a schedule that is accurate about the model but wrong about the building?
◦ What did your calculated field reveal that the plans did not?
You published two versions and compared them.
◦ Why does version history matter more on a shared model than a personal one?
◦ If a consultant says their work was based on last week's version, what do you need to be able to tell them?
◦ When should a model be formally issued rather than just saved?
