Abbreviations and Symbols
As in many technical fields, a wide array of abbreviations and symbols have been developed in engineering drawing during the 20th and 21st centuries. For example, cold rolled steel is often abbreviated as CRS, and diameter is often abbreviated as DIA, D, or ⌀.

Famous quotes containing the word symbols:
“If the Americans, in addition to the eagle and the Stars and Stripes and the more unofficial symbols of bison, moose and Indian, should ever need another emblem, one which is friendly and pleasant, then I think they should choose the grapefruit. Or rather the half grapefruit, for this fruit only comes in halves, I believe. Practically speaking, it is always yellow, always just as fresh and well served. And it always comes at the same, still hopeful hour of the morning.”
—Johan Huizinga (18721945)
