Notes on Drawings

Notes are used on drawings to supply information that cannot be presented in any other descriptive way. Notes are used for such an infinite variety of purposes that it is not practical to establish standard notes for every condition. A standard method of applying, placing, and revising notes on the engineering drawings should be used to maintain reasonable company-wide uniformity.

General Notes - General notes are those that apply to the drawing in total and would, if placed on the drawing at each point of application, become repetitive and time consuming to apply.

Local Notes - Local notes are those that apply to a particular portion, surface, or dimension on a drawing. Local notes indicate local or specific characteristics of a part, assembly, or diagram.
