After you specify the dimensional constraint type, you can either enter an
expression value or accept the default (constraintname=value).
The DIMCONSTRAINT command gives the same options as the following
commands:
Linear (
DCLINEAR on page 521) Creates a horizontal, vertical, or rotated
constraint based on the locations of the extension line origins and the
dimension line.
Horizontal (
DCHORIZONTAL on page 519) Constrains the X distance between
points on an object, or between two points on different objects.
Vertical (DCVERTICAL on page 523) Constrains the Y distance between points
on an object, or between two points on different objects.
Aligned (DCALIGNED on page 512) Constrains the distance between two
points on different objects.
Angular (DCANGULAR on page 514) Constrains the angle between line or
polyline segments, the angle swept out by an arc or a polyline arc segment,
or the angle between three points on objects.
Radius (
DCRADIUS on page 522) Constrains the radius of a circle or an arc.
Diameter (
DCDIAMETER on page 517) Constrains the diameter of a circle or
an arc.
Form (DCFORM on page 519) Specifies whether the dimensional constraint
being created is dynamic or annotational.
Convert (DCCONVERT on page 516) Converts associative dimensions to
dimensional constraints.
