To dimension a spherical feature using diameter, the spherical diameter symbol is placed in front of the size dimension, as shown below. This symbol is used to denote the diameter of a circle or cylindrical feature. For example, ø80 means that the diameter of a circle is 80mm. Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. Web various symbols and abbreviations in engineering drawings give you information about the dimensions, design, and materials used.
Radius symbol — a symbol indicating that the dimension shows the radius of a circle. Web the counterbore dimension contains the counterbore symbol, the diameter of the counterbore, and the depth of the counterbore. Circles on a drawing are dimensioned with a diameter. To dimension a spherical feature using diameter, the spherical diameter symbol is placed in front of the size dimension, as shown below.
Web various symbols and abbreviations in engineering drawings give you information about the dimensions, design, and materials used. In the example below, the drawing calls out five thru holes of a diameter between 0.531 and 0.546, each with a counterbore having a diameter of 0.813 to 0.828 and a depth of 0.520 to 0.540. A diameter symbol is used on the diameter dimension.
In the absence of a symbol, we assume a total wide zone. Radius symbol (r or ⌀ with a diagonal line through it): Web the radius symbol used is the capital letter r. Radius symbol — a symbol indicating that the dimension shows the radius of a circle. Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth.
