Dimensioning​.

Measurements are divided into the following main categories:

• Linear

• Angle

• Radius

• Diameter

• Coordinate

• Curve Length

• Area

The dimensioning functions make use of a variety of parameters that control the layout of the resulting measurements. When starting up a session, all these parameters are initialized from the default file of Drafting. Keywords and system values of these parameters are listed in Appendix G, Drafting Default File Keywords.

The layout parameter settings of the Linear, Angle, Radius and Diameter measurements do not normally influence each other. However, the Coordinate, curve Length and Area measurements share relevant layout parameters with the Linear set.

During a session, all parameters can be accessed and modally redefined:

• inside the dimensioning function(s) that utilizes the particular parameter

• by invoking the function 'Format-Defaults'

Below, the different dimensioning categories will be illustrated, All layout parameters together with their purpose are listed and exemplified. A particular parameter is denoted by its corresponding keyword in the default file, where the prefix LIN_, ANG_,RAD_ and DIA_ denote Linear, Angle, Radius, and Diameter respectively.
