7-18 Symbols and Abbreviations
Symbols are used in dimensioning to help accurately display the meaning of the dimension. Symbols also help eliminate language barriers when reading drawings.
Abbreviations should be used very carefully on drawings. Whenever possible, write out the full word, including correct punctuation. The Dimension PropertyManager Value tab includes a group of symbols and words commonly used on technical drawings. Figure 7-65 lists several standard abbreviations used on technical drawings.
Figure 7-66 shows a list of symbols available in the Dimension PropertyManager Value tab.
More symbols are available by clicking the More box. A list of available symbols will appear. Click a new symbol. A preview of the selected symbol will appear. Click OK and the symbol will appear on the drawing next to the existing symbol.
