It's very likely you'll need to dedicate more sheets and have larger scaling to smaller sections of risers, versus a CAD single-line isometric representation. You'll need to think about how you want 3/4" pipe to display versus 4"/6"/8" mains. Lineweights are not friendly to small pipe on big drawing scale.You can get around this with a generic, invisible family placed in the inner centroid and populated with the room data, tagging the generic family (I would recommend Dynamo for this type of workflow). Revit doesn't allow room/space annotation in 3D view.If the project is too big then it's just End-to-End callouts everywhere. M4 ISO generates a fully dimensioned piping isometric drawing from the PCF file, together with a parts list. The PCF file fully describes the 3D pipework and is a standard file format. Displacements get shown with detail lines or with End-to-End reference callouts. A PCF file is generated by piping design systems from 3D pipework models. If the project size permits, I drop these onto a common sheet with a 3D view dedicated to the pipe mains to show the interconnections without being stuck with perspective overlaps. Personal workflow is to capture major or common stacks within a scope box, stacking 3D views dedicated to each scope box.It presents itself as a really clean solution on a completed riser, but modifications afterwards can sometimes not displace appropriately leading to hanging pipe or text. Exploded view in Revit can work, but runs into a few issues regarding mid-project riser modifications and annotations. Original post is old but some considerations:
