Forces two lines or linear polyline segments to be parallel to each other. (This command is equivalent to using the Parallel option of the GeomConstraint command.)

**Note**: The second entity that you select is moved to be parallel with the first entity.

## Accessing the Command

command bar: **gcparallel**menu bar:

**Assembly**

**| 2D Constraints | Parallel**

ribbon:

**Parametric | 2D Constraints | Parallel**

toolbar:

**2D Constraints |**

: **GcParallel**

**Prompts you in the command bar:**

Select first entity: *(Select a line or linear polyline segment)*

Select second entity: *(Select a line or linear polyline segment)*

## Command Options

Description |

Select first entity |
Select a line or linear polyline segment. |

Select second entity | Select another line or linear polyline segment. |

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:
