The ribbon geometry requires an array of paths at construction time. If you pass only one path in the array, you need to create at least four points and set the offset value.

Thanks a lot for quick reply jerome. i can add the 4 points instead of three here.

What other shape should be a good option for 3 points?

The real question is : what do you intend to do ?

Usually, the best and easiest way to deal with ribbon is to set an array of paths (at least 2, each containing 2 or more points)

For 3 points perhaps either of these is a better option
