IFC is a format for exchanging models with data attached between different software. IFC elements are 3D construction elements and objects. IFC has nothing too with plans, annotation, or anything 2D.
The only consultant I have worked with is StructureCo, which is a pseudonym. The type of work is custom residential -- mostly wood members with some steel. This is our first try at this type of coordination.
My goals for the StructureCo collaboration:
• If I can get the beams labeled in the sections, and check that the structural elements fit, I can let them do the framing plans.
• Automatically label elements based on data provided within them, such as ID or profile.
• Let their layer names come through, with an extension.
• Bring in elements with proper classification.
• Avoid creation of attributes other than Complex Profiles.
• Let the consultant do the model 'their way' as much as possible. We try to be low-maintenance teammates.
In other words, let them do some of the work without sacrificing the consistency of our model and annotation process.
