Generating CDs from Revit

Generating CDs from Revit

Generating CDs from Revit

(OP)
Wondering how others do this.

Do you generate all your CD's (GSN, details, plans) from the Revit model or do you limit the CD generation to the plans and do your GSN and details in 2D CAD?

First time being involved in a project entirely being done in Revit and it is very frustrating.

I have ACAD experience and have done my own CAD in the past and also have some exp. in 3D modeling but zero Revit exp. Someone else is doing the modeling and this is where it gets frustrating. A couple of details /section that would only take 30 minutes in CAD, would turn into an all day affair updating the 3D model.

I don't get that the smallest details / changes would need to be plugged into the model when at the end of the day, it is the 2D CAD that will get submitted for permit and becomes the contract documents. The Revit model is simply being used for coordination and I guess, because the architect requires it.

Anyone would bother to educate me on the best practices?





RE: Generating CDs from Revit

We use REVIT for the bigger parts of the model, but many of the detail views are 2D sketches in REVIT, or a REVIT view with 2D lines drawn in the detail. We do not model all the little bits and bobs.

RE: Generating CDs from Revit

We draw all our details and schedules in 2D CAD outside of Revit.

RE: Generating CDs from Revit

I draw all sections and details in CAD(2D)and import them into Revit, and the structural drawings are produced in Revit. I model as little as possible in Revit, consistent with what we are contractually required to provide. We primarily consult for architects and they are our clients, who up to this point have required us to provide them a structural revit file ONLY for coordination (no BIM level of development specified) and for them to link into their arch revit file. Thus, for the time being anyway, from a structural standpoint, the contractor, construction manager, fabricators, suppliers, etc., are simply using the 2D contract documents (30X42 drawings and specifications) to fabricate and build from. Therefore, in order to excecute the projects as efficiently as possible under this arrangement (2D construction document deliverables but give arch and other consultants the struct revit file for coordination), I model as little as possible (primary structural framing, columns, foundations) in revit, add necessary annotations, notes, etc., to plan views, and then import in sections and details in CAD (with years of past projects to draw from and use/modify). There are many things I love about revit, but after two years of working with revit (mainly on larger projects with say 30, 40, or even 50 structural sheets), even with the minimal modeling, it still takes longer to complete a project (for a variety of reasons) than with all AUTOCAD as before. Things are constantly changing; my reply may be obsolete and overtaken by events by tomorrow or next week/month/year,but for now this is my situation.
