Constrains two splines to maintain fluid geometric continuity between them. (This command is equivalent to using the Smooth option of the GeomConstraint command.)

**Note:** The second spline that you select is adjusted to smoothly connect to the first spline.

## Accessing the Command

command bar: **gcsmooth**menu bar:

**Assembly**

**| 2D Constraints | Smooth**

ribbon:

**Parametric | 2D Constraints | Smooth**

toolbar:

**2D Constraints |**

: **GcSmooth**

**Prompts you in the command bar:**

Select first spline curve:*(Select a spline)*

Select second entity:*(Select another spline)*

## Command Options

Description |

Select first entity | Select a spline |

Select second entity | Select another spline; this spline bends to meet the first one smoothly; see figure below |

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.

Pause the cursor over one of the icons to see the location of the constraint, shown as a large **X**:

To remove a constraint, click the tiny** x** on the constraint bar.
