Constrains one line or polyline segment to be collinear with another one, which means they lay in the same line. (This command is equivalent to using the Collinear option of the GeomConstraint command.)
Note: The second entity you select is straightened out to be collinear to the first.
Accessing the Command
command bar: gccollinear
menu bar: Assembly | 2D Constraints | Collinear
ribbon: Parametric | 2D Constraints | Collinear
toolbar: 2D Constraints |
: GcCollinear
Prompts you in the command bar:
Select first entity or [Multiple]: (Select a line or polyline segment, or press M)
Select second entity: (Select another line or polyline segment)

Description |
Select first entity |
Select a line or polyline segment. |
Select entity to make collinear to first |
Select multiple lines or polyline segments; segments of the same polyline are accepted, which is straightens out the polyline. |
Multiple |
Makes more than two entities collinear; you can pick only one entity at a time. Prompts you:

After you place the constraint, icons appear near the entities indicating the type of constraint. If you do not see them, then use the ConstraintBar command to display them. To remove a constraint, click the tiny x on the constraint bar.
