2022年9月28日 · The Radius symbol is used to indicate that the size of a circular feature is being dimensioned using the radius length, which is half of the diameter length. Because a circle can be dimensioned using its full diameter or radius, the diameter or radius symbol MUST be indicated on the dimension so there is no confusion over the size of the feature.

2017年10月1日 · Radius (R)- A straight line extending from the center of an arc or circle to its surface. Controlled Radius (CR) - C reates a tolerance zone defined by two arcs (the minimum and maximum radii) that are tangent to the adjacent surfaces.

2020年10月21日 · Basic types of symbols used in engineering drawings are countersink, counterbore, spotface, depth, radius, and diameter. Here are more commonly used engineering drawing symbols and design elements as below. You can also check out the GD&T symbols and terms on our site.
Engineering drawing abbreviations and symbols - Wikipedia
controlled radius: Radius of an arc or circle, with no flats or reversals. This strict version of radius definition is specified in demanding applications when the form of the radius must be controlled more strictly than "just falling within the dimensional tolerance zone".
General symbols are used with dimensions to clarify the requirement defined by a dimension value and to minimize the number of words or abbreviations placed on a drawing.

Diameters must be dimensioned with the diameter symbol preceding the numerical value. When holes are dimensioned with a leader line, the line must be radial. A radial line is one that passes through the center of a circle or arc if extended. Symbols may be used for spotface, counterbore, and countersunk holes.

Controlled Radius - The as-manufactured controlled radius surface must be a fair curve without having sharp corners and reversals. Coplanar - Coplanar describes a condition of two or more surfaces having all elements in the same plane.
Radii: Radius in Technical Drawings
Radius refers to the measurement of the curved surface on a part, both on the inside and outside. They are also used to indicate the rounding of edges at connecting surfaces, called fillets, to increase strength. The radius is denoted by an "R" before the measurement.
Drafting Symbols Symbols provide a “common language” for drafters all over the world. However, symbols can be meaningful only if they are created according to the relevant standards or conventions. This document describes and illustrates common dimensioning, GD&T, architectural, piping, and electrical symbols. Standard Dimensioning Symbols
