The Polyline Command

Toolbar: Draw
Pull-down: DrawPolyline
Keyboard: PLINE short-cut PL
The Polyline or Pline command is similar to the line command except that the resulting object may be composed of a number of segments which form a single object. In addition to the two ends a polyline is said to have vertices (singular vertex) where intermediate line segments join. In practice the Polyline command works in the same way as the Line command allowing you to pick as many points as you like. Again, just hit

to end. As with the Line command, you also have the option to automatically close a polyline end to end. To do this, type C to use the close option instead of hitting

. Follow the command sequence below to see how this works.

Command Sequence
Command: PLINE
Specify start point: (pick P1)
Current line-width is 0.0000
Specify next point or [Arc/Halfwidth/Length/Undo/Width]: (pick P2)
Specify next point or [Arc/Close/Halfwidth/Length/Undo/Width]: (pick P3)
Specify next point or [Arc/Close/Halfwidth/Length/Undo/Width]: (pick P4)
Specify next point or [Arc/Close/Halfwidth/Length/Undo/Width]: (pick P5)
Specify next point or [Arc/Close/Halfwidth/Length/Undo/Width]: (or C to close)

In the illustration on the right, the figure on the left was created by hitting

the key after the fifth point was picked. The figure below demonstrates the effect of using the Close option.

It is worth while taking some time to familiarise yourself with the Polyline command as it is an extremely useful command to know. Try experimenting with options such as Arc and Width and see if you can create polylines like the ones in the illustration above. The Undo option is particularly useful. This allows you to unpick polyline vertices, one at a time so that you can easily correct mistakes.

Polylines can be edited after they are created to, for example, change their width. You can do this using the PEDIT command, Modify

Object

Polyline from the pull-down menu.
