# Polyline

The **polyline** command draws a multi-segment line with options for line and arc segments, tracking line helpers, and close.

## Insert a polyline

Steps:

- Pick the start of the first segment.
- Pick the end of the first segment. Use object snaps to reference existing geometry. This is also the start of the next segment.
- Continue picking until the polyline is complete, and press Enter.

## Command-line options

**Close**

The Close option appears only after three points have been placed. Closes the curve.

**Helpers**

Turns on dynamic tangent and ortho tracking lines that make it easier to extend arcs with lines and draw arcs aligned x and y axes.

**Length**

Sets the length for the next line segment.

This option is only available when the Mode option is set to Line.

**Mode**

Controls whether line segments or arcs are drawn.

**Line**Sets the drawing mode to line segments.**Arc**Sets the drawing mode to arc segments.**Direction**

Lets you pick a point to show the direction of a line tangent to the arc's first end point.**ThroughPoint**

Lets you pick a point that the next arc segment will pass. The arc segment will not tangent to the previous segment.**Center**

Lets you pick a center point for the arc's radius.

**PersistentClose**

Closes the curve as soon as there are two points placed.

If you continue to pick points, the curve updates the shape while remaining closed.

**Undo**

Reverses the last action.
