To draw a series of connected lines (polyline)

1. Click the Polyline icon, or choose Lines > Polyline from the Keypoint Curve Toolbox.
2. Click to place the starting point for the polyline, or type a 3D coordinate to place the point exactly.

   If you click the endpoint of an existing keypoint curve, the new line attaches itself to the end of the existing curve to create a composite curve.

3. Click to place the next point in the polyline, or type a 3D coordinate to place the point exactly.
   • Click the to add the point freely.
   • Click the to align the point horizontally to the first point.
   • Click the to align the point vertically to the first point.

   As you drag the end point, the Polyline tool displays the length of the line in current linear units.

4. You can now:
   • Repeat step 3 to add another line segment.
   • Click the Polyline tool to start another polyline.
   • Click any other tool to finish the polyline.

Tips and notes

• You can use guidelines and curve snapping curve to draw parallel lines, tangent lines, perpendicular lines, and right angles quickly.
• You can use Edit > Undo to undo points in a polyline all the way back to the start point.
