A complete dimensions are combined by extension lines, dimension lines, dimension text, arrowheads and center mark etc..
extension lines.. Drawing from the contour line, the axis or center line of symmetry. Sometimes, it can use the contour line to define the starting point. Normally, the extension line is vertical to the dimension line.
A dimension line. Indicates the direction and extent of a dimension. For Linear Dimensions, the dimension line is a linear portion. For angular dimensions, the dimension line is an arc.
Arrowheads. You can specify different sizes and shapes for arrowheads or tick marks.
Dimension text is a text string that usually indicates the measurement value. The text can also include prefixes, suffixes, and tolerances.
A center mark. Indicates the center of a circle or arc.
