DCLINEAR (Command)

Creates a horizontal, vertical, or rotated constraint based on the locations of the extension line origins and the dimension line.


This command is equivalent to the Linear option in DIMCONSTRAINT.

The following table outlines the valid constraint objects and points:

Valid Objects or Points



Polyline segment


Two constraint points on objects

  • When a line or an arc is selected, the horizontal or vertical distance between the endpoints of the object is constrained.

The following prompts are displayed.

Constraint Point

Specifies a constraint point for the object.

First Constraint Point

Specifies the first point of the object to be constrained.

Second Constraint Point

Specifies the second point of the object to be constrained.

Dimension Line Location

Determines where the dimension line is located on the constrained object.


Selects an object instead of a constraint point.
