Normally, a dimension is composed by a dimension line, a text or value, two extension lines, and two arrows. The most common dimensions are linear, presented next.
Note
When creating the first dimension in a drawing, a layer called Defpoints is added to the drawing. This layer stores the points that define dimensions and can not be purged, even if it is empty. However it can be renamed.
Dimensions are placed in the current dimension style. The dimension style controls all geometric and unit's parameters. The PROPERTIES
palette can be used to apply other dimension style to selected dimensions.
