My goal is to always leave a healthy amount of white space on every drawing, for two reasons. Drawings are working documents, and the information they contain is all-important. The purpose of a drawing is to convey information, both graphical and textual. Not cluttering drawings sounds easy, but isn't always. So briefly: How to design a schematic project? What's the order of operations? How not to clutter the drawings? Really, books could be written addressing just these three issues. So sometimes, your 'standards' depend on the industry.Īs to your original post: In short, there is not a single place that will answer all of your questions. The company where I work builds equipment that supports the local bourbon industry, and we have our own guidelines to follow for working with flammable vapors/liquids in hazardous areas - they're like an adjunct to NFPA 79, designed to address industry-specific concerns. there tend to be lots of bulkhead connectors and such. Their schematics (along with most milspec schematics) can get pretty ridiculous. Sometimes, the nature of the industry makes things harder, for instance, aircraft design. Railroads come to mind, everything they do just *has* to be different from what everyone else does.
Often, industries have their own 'ways of doing things' that are unique to them.
The most common reality for most of us is another thing TRLitsey said: just meet the needs of the client/customer. As such, their implementation tends to vary widely across America (and, I assume, the rest of the continent). However, there is no binding authority that says we have to abide by these standards. For all intents and purposes, these are our main 'standards' documents in the US for industrial design. Now, that's *actually* not true - we do have the NFPA 79, of which the NEC (National Electric Code) is also a part. That being, that we don't really have one. It alone will highlight one of the problems we have with the word 'standards' here in North America. So, following TRLitsey's example, I attached a drawing index from one of our recent projects.
