It's the same with the dinosaur engineers in here, "We fear change". Change can sometimes be for the better.
It's not change we fear, it's change for the sake of change, or worse, change to something that bloody doesn't work. Cryptic alpha-numeric layer names are NOT "better", just cryptic.
For the record, the dinosaurs thing wasn't directed at you or anyone else here, it was directed at the engineers in my office who are "in charge" of the CAD operation but can't open a drawing, and won't let me change it for the better.
As for cryptic, 99.99% of building construction companies in the UK know these numbers, and they know them because they are a standard series.
I've been doing this job for over 17 years and In all that time no company I've worked for has ever used anythng except the CIBSE matrix codes.
What this requires most of all is for people to adopt the standards, because if they don't then we all remain doing our own thing, and electronic cad drawing file excahnges remain cryptic to anyone who doesn't know your system.
At the moment i'm tryiong to get a copy of the Architects matrix codes, (different standard), to try to decypher their drawings. But if they used the ISO standard I wouldn't need to because it would use the same codes for every job, and eventually I'd klnow what they were.
and that's my point, if we all use the ISO then everyone is in on it, and everyone would be able to understand the layouts.
Architects could use the steelwork drawings, and building services could use both with practically no changes being required.
I dream of the day where we all use the same standards to draw with, you could cut my workload by half just by doing this.
