Last week, our Virtual Construction team sat down with the CAD Manager of our HVAC subcontractor for Autodesk. In our discussions, a recurring topic came up – why they can’t use Revit MEP for fabrication. One of the major reasons is spooling, which he had mentioned several times before, but hadn’t explained.

After they model and coordinate HVAC, they take the model and review for pre-fabrication. During this review, they bring up the model and select sets of components to pre-fabricate. From what I understand, they select each group of components and turn them into the equivalent of a Revit Group. The software automatically (sort of) creates cut sheets for each group, with dimensions, sizes, lengths, etc.

I didn’t realize that this was something that a software program could do and am amazed at how efficient it seems. Although I’m sure there is some work involved, this is the type of thing that we would like to do for all trades – select a group of objects that will be built/installed at the same time (for instance, a group of footings and foundation walls). “Cut sheets” would be automatically created, based on the selected objects sheets”, which would contain 2D and 3D views, dimensions, quantities, etc. Although, we wouldn’t want to use the term “Group” because it already exists in Revit. We could call it ‘Task’ or ‘Week’ – which makes a lot of sense, considering this is basically a schedule. Kind of like our Sequence Sheets (manually created for a project using Phasing in Revit), but a lot less work.

So does Revit MEP already output this information upon "grouping" the selected objects?

I worked for a piping fabricator who performed their spooling the old fashioned way on our biggest project ever and we found it quite challenging. (Senior employees would sit for hours “breaking up the system” using red pencils in BIG books. The CAD drafters would then utilize third party software to regenerate the spools in an isometric view and it was tedious, and made a lot of room for error. I could see this as being very beneficial for them in the future, and eliminate the room for error that we encountered.

Revit MEP doesn't do spooling.

Many other fabrication-specific software programs do, though.
