I work in BIM and somtimes spend a lot of time converting CAD drawings into models. Every time we pick up a file — whether it's an old project, a consultant's drawings, or a handover from another office — there's a baseline mess to deal with before anyone can actually work with it. Layers no one purged, lines that look connected but aren't, hatches that don't close. Same stuff regardless of source.
Curious how this is handled on the architecture side. Is there an actual office standard or QC step before files go out (or come in), or does everyone just deal with it case by case? Especially interested in how mid-to-large practices keep it from becoming someone's full-time job.
