Lines vs Polylines

What is a Line?

Think of a Line like a single piece of string. If you draw a square using four separate lines, you have four individual pieces. If you try to move or change the square, you have to click and edit all four pieces one by one.

What is a Polyline?

A Polyline connects those pieces into one single object. Instead of four separate lines, your square is now a single shape that stays glued together.

Why are Polylines better?
