**1. A concise explanation of the problem you’re experiencing.**

I want to add an arrow-like effect to CZML.

This request was mentioned before the forum search found.

But the reply says that CZMldoes not support arrows.

So now CZMl supports the arrow?

How can I do it?

thanks.

Although it won’t look exactly like the picture you have. You might have to create multiple line segments to get a similar effect. I hope this helps!
