Applies dimensional
constraints to selected objects or points on objects, or converts
associative dimensions to dimensional constraints.
Summary
Applies a dimensional constraint to a selected
object or converts an associative dimension to a dimensional constraint.
NoteThe L option (last
object drawn) is not allowed in the DIMCONSTRAINT command as the
constraint behavior is dependent on where you pick the object.
The following table outlines
the valid constraint points for an object.

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)
-
Creates a horizontal,
vertical, or rotated constraint based on the locations of the extension
line origins and the dimension line.
- Horizontal (DCHORIZONTAL)
-
Constrains the X distance
between points on an object, or between two points on different
objects.
- Vertical (DCVERTICAL)
-
Constrains the Y distance
between points on an object, or between two points on different
objects.
- Aligned (DCALIGNED)
-
Constrains the distance
between two points on different objects.
- Angular (DCANGULAR)
-
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)
-
Constrains the radius
of a circle or an arc.
- Diameter (DCDIAMETER)
-
Constrains the diameter
of a circle or an arc.
- Form (DCFORM)
-
Specifies whether the
dimensional constraint being created is dynamic or annotational.
- Convert (DCCONVERT)
-
Converts associative
dimensions to dimensional constraints.
