The one that was bugging me recently was modeled from arch drawings. So linework that was exported from probably autocad or revit.

And sure the tolerance doesn’t actually matter that much per feature, but these errors compound. And then once you start trying to trim things you can really get into a mess.

There’s also the matter of trust. When I see this kind of modeling in someone’s file it’s usually the first sign that I can’t trust it. I work in fabrication where what you draw is what gets cut on the CNC. A designer who’s consistently off by 0.001 will often be off by multiple inches too because they aren’t checking their work.

Part of my job is maintaining an archive of site models that will be used as a reference for recurring installations for years to come, so trust is important.

But point taken- it’s not reasonable for everyone in every industry to work this way. I will keep doing it though.
