# Draw Polyline

The **Draw Polyline** option allows you to draw an arbitrary polyline consisting of any number of line segments. To add a **Polyline**:

- Select the
**Geometry**workflow tab. - Select
**Draw Polyline**option from the toolbar or**Polyline Tools**section in the**Geometry**menu. - Define the current plane in which all polylines coordinates must lie on by defining an origin point and normal vector. The normal vector is defined by the
**Plane Orientation**options and can be any of the default XY, YZ, or ZX planes as well as a custom plane. In the**Plane Options**section, define the origin point of the plane. In the case of a custom plane, you will be able to define both the origin point and normal vector in the**Plane Options**section. - Select a
**Path Definition**. This option allows you to draw:- P-line: Each entered vertex will generate a new line segment.
- Arc: Draw a curved polyline using
**3 Points on Arc**, the**Start, Center and End**points or the**Start, Center and Angle**. For the**Start, Center and Angle**option, the Angle is measured counterclockwise about the selected plane normal from the start to the center point. - Curve: Not available at this time.
- Circle: Draw a polyline circle by entering the
**Center, Point on Circle**, center point of the circle and a point along its circumference. You can also use the**Center and Radius**option to enter the center point of the circle and its radius length. - Ellipse: Not available at this time.
- Rectangle: Not available at this time.

- Enter points graphically with the mouse, or enter coordinates in the
**Coordinate Input**section. You can either type each coordinate in the input box or enter it into a table using the**Edit Table**option. The**Coordinate Input**section uses relative positions (**U, V**) from the plane origin where**U**represents the horizontal displacement from the origin and**V**represents the vertical displacement from the origin. It is important to distinguish the horizontal and vertical axis of the current drawing plane. You can easily find this information from the 2D viewport used to preview the drawn polyline. The horizontal and vertical axis of the viewport correspond to current**U**and**V**axes. - Accept or reject the drawn polyline to close the drawing pane.
