All, this was a poorly expressed question on my part, hurried at the end of a hurried day. Chris, you are correct, and ASME states this very fact in the standard. Thank you.
The company I work for has standardized it's processes as part of a successful ISO registration. Our engineering department does not currently conform to an industry recognized standard for our drawings. We are primarily a contract fabricator but we are beginning to perform design work for our own products and for other companies.
For those of you who have been involved in the development of an internal drawing standard, I would appreciate your suggestions as we create or adopt a drawing standard.
Kind regards, Diego
