My first post here - woo hoo!
CAD Standards are the holy grail of drafting/design. I haven't been able to read a full copy of the NCS, just the samples they have on the website. I personally can't afford it and the companies I have worked with in the recent past refuse to buy it. Heck they didn't even see a need for standards. (pulling hair out -running, screaming)
Anyway, based on what I have seen/read it seems to be geared toward architecture and building plans. I work in the oil and gas industry and previously in nuclear power generation. What I have done is piping, plant design, and recently electrical power distribution & controls. What I have seen in the NCS is helpful in that I could create a standard from scratch based on their guidelines/information, but it would not be exactly like theirs.
While working in nuclear power generation standards was not an issue. We had standards, procedures and guidelines for everything we did. Document Control and Records Management was tight as a tick. I miss that environment in that there is a certain comfort working to procedures and standards. You know what to do, how to check yourself and there isn't any guess work. Is it challenging and fulfilling working that way? For me it was I always knew I was doing a good job.
FWIW that's my two cents about the NCS.
