Symbols, Terms, and Rules
Symbols, Terms, and RulesSymbols, terms, and rules are the basics of geometric dimensioning and tolerancing (GD&T). They are the alphabet, the definitions, and the syntax of this language. The GD&T practitioner must be very familiar with these symbols and know how to use them. It is best to commit them to memory. Can you imagine trying to read a book or write a composition without knowing the alphabet, without a good vocabulary, and without a working knowledge of how a sentence is constructed? A little memorization up front will save time and reduce frustration in the future.
