In 2D CAD where different kinds of related layout drawings are created, there is need for all disciplines (structural, equipment layout, piping, electrical, etc.) to coordinate what levels, line weights, text heights, colors, and scaling each is using. It is very helpful to use reference files that let you selectively turn things off and on. Many disciplines will place graphics and text that will be referenced by others. It is helpful to view and print certain graphics and text in the referenced files while turning off others that do not pertain to your drawing. The decision process for the team is to list what each wants to view from others drawings. Then it will be easy to agree on levels, etc. for those things needed by each discipline. It is not difficult to determine the major things and the team should strive to identify everything. Every CAD operator will see the benefit and have pride that others save time by attaching their drawings as reference.

The Process Industries Practices (PIP) organization based in Houston, TX, has created numerous standards and specifications that thay hope will be in wide use by the process industry. There is a fee for membership. Many owners will provide copies to their contractors. I suggest you check to see if PIP has created a CAD standard that suites your needs. They have a large set of piping specifications and P&ID standards that should be very helpful to companies that have not kept theirs up to date.
