BiM and Process change

Be prepared to work in much tighter, more collaborative teams. As soon as you enter the BIM
multiuser world, you absolutely need to be communicating with your team all the time. The
changes that you make in the model will affect the whole model and other people’s work. We
think this is a great—perhaps unintended—consequence of moving into a model-based design
paradigm.
Anticipate that tasks will take different amounts of time when compared to a CAD produc-
tion environment. You’ll perform tasks in Revit that you never had in CAD; and conversely,
some CAD tasks that took weeks (such as chamfering and trimming thousands of lines to draw
walls properly or making a door schedule) take almost no time using Revit. On the other hand,
some tasks may seem to take longer in Revit. This may initially seem true, but remember that as
you’re modifying or adding something in plan, you’re also adding it in section, elevation, and
detail. Be prepared to discover and embrace new tasks with BIM that were never part of a 2D
workflow.
In Revit you’ll often feel as if you are working in traditional types of 2D views—just keep
in mind that it’s still a 3D model. Moving walls, windows, and doors in plan feels like a 2D
operation, but of course it’s not. If you’ve never worked in a model-based environment, it can
be jarring at first to see the drawing you’ve been working on change as a result of an edit in a
different view. As we mentioned, this becomes even more dramatic when you start working in
a team and sharing a model. You’ll learn that preventing movement of elements becomes just
as critical as being able to edit elements in the model. Pinning down grids, levels, and exterior
walls will become part of your workflow, especially in larger projects with many users working
in a single file.
