Dimension Lines. Dimension lines are used to indicate the size and location of features in an engineering drawing. They provide measurements that define the length, width, height, or diameter of objects, allowing for accurate replication and manufacturing.
Dimension lines serve to illustrate the orientation and extent of specified length or size. If there is room for the line and the arrowhead, it is preferred that dimension lines be placed between the extension lines. Extension lines are used to clarify the points at which a dimension begins and ends. Dimension lines show the length of the ...
Dimension and extension lines are used to indicate the sizes of features on a drawing. Section lines (hatching) are used in section views to represent surfaces of an object cut by a cutting plane. Phantom lines are used to represent a movable feature in its different positions.

Dimension and extension lines (Figure 6) are thin, solid lines that show the direction, length, and limits of the dimensions of a part. Dimension lines are drawn with an arrowhead at both ends. Extension lines are drawn close to, but never touching, the edges or surface they limit.
Extension Lines. Extension lines on a drawing are fine, dark, solid lines that extend outward from a point on a drawing to which a dimension refers. Usually, the dimension line meets the extension line at right angles.
numerical value of a dimension expressed in a specific unit and indicated on drawings with lines and relevant symbols. Note 1 to entry: When no tolerance is indicated, the basic dimension is often called the dimensional value. Note 2 to entry: Unit of dimension should be linear or angular.
