Creates a 3D polyline.
A 3D polyline is a connected sequence of straight line segments created as a single object. 3D polylines can be non-coplanar; however, they cannot include arc segments.
The following prompts are displayed.
Draws a straight line from the previous point to the specified new point. The prompt is repeated until you press Enter to end the command.
Deletes the last line created. You can continue drawing from the previous point.
Draws a closing line from the endpoint back to the first point, and then ends the command. To be closed, a 3D polyline must contain at least two lines.
