What are the benefits of polyines?

[R-man]

So far I have done everything I needed by simply using regular lines, arcs, circles etc. Out of curiosity I decided (about an hour ago) to experiment with polylines. So far I can't see that they would be of any benefit to me.

However I must assume that they have redeeming qualities that I have yet to discover. So If anyone can describe a benefit, ideally accompanied by a simple code example, it would be really helpful.

As far as I can tell the polylines can only be made up of lines (arcs and circles are broken into line segments). It does have some nice things like being able to rotate, combine, and split polylines which can then be added to a sketch.

Thanks Nate. Your reply says it all.
