DcAligned

Constrains the distance between two points or the length of a line or polyline segment.

This command is equivalent to the Aligned option of the DIMCONSTRAINT command.

Accessing the Command

command bar: dcaligned

menu bar: Parametric | 2D Constraints | Aligned

toolbar: 2D Constraints |

: dcaligned

Prompts you in the command bar:

Specify first constraint point or [Entity/Point/2Lines] <Entity>: (Select a valid constraint point or choose an option.)

Specify second constraint point: (Select a valid constraint point.)

Specify dimension line location: (Select a point to position the dimension line.)

Dimension text <xx.xx>: (Type a value or press Enter to accept the current value.)

The distance between the selected points is constrained.

Command Options

Option	Description
Entity	Constraints the length of a line, a polyline segment or the chord of an arc. Prompts you: Select an entity - Select a line, polyline segment or arc. Specify dimension location - pick a point. Dimension text <xx.xx> - type a value or press Enter to accept the current value.
Point	Constraints the perpendicular distance between a point and a line or polyline segment. Prompts you: Specify constraint point or [Line] <Line> - select a valid constraint point or choose the Line option to select the line or polyline segment first, then the point. Select line - select a line or polyline segment. Specify dimension location - pick a point. Dimension text <xx.xx> - type a value or press Enter to accept the current value.
2Lines	Constraints the distance between 2 lines or straight polyline segments. If the entities are not parallel already, the second entity is rotated around its midpoint. Prompts you: Select first line - select a line or polyline segment. Select second line to make parallel - select a line or polyline segment. Specify dimension location - pick a point. Dimension text <xx.xx> - type a value or press Enter to accept the current value.
