There are three main types of shifts in Illustrator: portrait, landscape, and vector. Portrait Shifts: In a portrait shift, the object is drawn from the front of the canvas to the back. This is the most common type of shift in Illustrator. Landscape Shifts: In a landscape shift, the object is drawn from one side of the canvas to the other. This is often used for illustrations that feature large landscapes or for illustrations that need to be stretched out horizontally or vertically. Vector Shifts: A vector shift is when an Illustrator object is drawn using vectors instead of lines. This can be used for illustrations that need to be stretched out horizontally or vertically because vectors can create more space than lines.
