Isometrics and Cut-sheets
Isometrics and Cut-sheets
(OP)
Hi,
What is the purpose of a cut-sheet? Isn't all the information for fabrication on the actual ISO? Further, aren't you only supposed to build off of IFC ISOs? Is the sole purpose of the cut-sheet to show where the FWs are, and thus call out spool numbers?
Thanks

RE: Isometrics and Cut-sheets
I've always called what you're referring to as spool drawings. They are generally provided by the piping fabricator. In the old days, creating these used to be an entry-level job for a piping draftsman, allowing up close detailed exposure to the fabrication process. Now it's often partially automated by software like SpoolGen or AcornPipe.
A 'cut sheet' can also refer to a catalog sheet depicting equipment or components.
As-builts (if ever done) are generally markups of the isometric (not the spool drawing) depicting the actual installed piping. In my experience, these are not always done, since there never seems to be time/money near the end of the project and it's easy to just let this slide.
