### Curve Menu

All of the commands and options in this menu require a curve is selected.

#### Smooth

Gently smooth out a curve. This command is easier to use from the keyboard - press and hold S until the curve is adequately smoothed.

#### Clone

Make a clone of this curve. You will need to move the new curve away from the original to see them separately.

#### Mirror Clone

Whereas "M" symmetry creates a virtual fourth line for a lathe object, Mirror Clone can be used to create a real fourth line opposite the third, and since this avoids using symmetry the map can be different on either side of the model.

#### Redraw As...

To make accurate geometric curves and perfect spheres and ellipses use these commands to turn rough shapes into exact curves. Redraw As... Semi-Circle is especially useful for making spheres, Redraw As... Straight-Line helps make flat planes out of loft objects.

#### Draw Smooth Lines

This option means any lines you draw will be automatically smoothed before being added to an object. This is good for natural shapes.

#### Draw Precise Lines

This option turns off automatic smoothing. This is useful for drawing square corners and rough ragged lines.
