2025-11-24 – Weekly CAD News : File naming chaos in CAD projects

Last week, the forum buzzed with discussions around common challenges and best practices in CAD workflows. Members shared insights into file naming conventions, debated the intricacies of parametric checks in ShipConstructor, and explored how to ensure quality in IFC exports. There was also curiosity around industry standards for drawing revisions, which sparked a lively debate.

We cut naming chaos by locking filenames to a simple pattern and keeping revs out — “the filename should never lie” — then using a PDM check‑in rule to reject off‑pattern files. Caveat: for external PDFs we append -RevX on publish so email threads don’t implode; herding cats became herding one cat.

Switched to auto‑generated, ID‑first filenames (PROJ-DS-000123) and keep rev/title in properties, building on @hmoore99’s “filename should never lie” — stops filenames breeding like rabbits. A tiny pre‑check blocks spaces and duplicate IDs; without PDM, the ISO 19650 pattern works in a pinch but gets rigid on multi‑discipline packages (https://www.ukbimframework.org/).

ISO 19650 naming, filenames static; Excel pre-check flags mistakes before IFC export. https://www.ukbimframework.org/.

Quick example: for our weekly IFC exports, we run a tiny pre-export script that copies models to a “staging” folder, normalizes names (no spaces, zero‑padded IDs), and aborts if any two would collide. It cut cleanup time a ton and costs nothing to maintain, but it won’t catch broken xrefs across disciplines, so we still do a quick visual pass before publishing.

We added a Vault rule: block duplicate drawing numbers; helps revisions, but SharePoint still breaks case… @hmoore99.
