While working with arrows and lines, you will notice that they stick at some point to elements that you approach. This is the main feature of working with lines and arrows, and it’s handy because when you move one element around, the arrow or line will change accordingly because they are stick.
You will also notice that when we select an arrow or line, they have three dots, one at the beginning, another in the middle, and the last one at the end. With the middle dot, we can change the curvature of it.
