Drawing general notes library
152 copy-ready general notes for mechanical drawings, grouped by process, in English and Spanish. Each note says when to use it, the mistake to watch for, and the standard behind it. Search all of them below, or open a set.
Values in [brackets] are examples; replace them with your own. Notes marked Verify values rely on common practice; confirm them with your supplier or design engineer. These notes are examples, not an engineering approval of your drawing.
