Function
Description
Examples
The chain dimensions are defined by means of two points for the projection lines and one point for the dimension figure. The succeeding points can then be identified for further dimensions.
The parallel dimensions use the point options to define the first steps by means of the start and end points of a line. The third point specifies the position of the dimension figure and the succeeding points specify the further steps.
Running dimensions are chain dimensions with the same reference point. The dimension figures refer to this point.
Height above datum is a type of dimensioning used in steel engineering.
You first specify the points to dimension and the position of the dimension figure and then define the succeeding points.

Height above datum
In coordinate dimensioning, the first point is the reference point. From there, the dimensions are calculated in x or y direction. The second point defines the dimension section. The third point specifies the calculation of the dimensions in x or y direction and the position of the dimension figure. The succeeding points identify further dimension sections.
