I have a quick beginner question. How do you find the vanishing point(s) without a reference or photo? Do you just put it anywhere you want or is there a method? I've tried googling this but I only found how to find the vanishing points in photos.
Are you drawing from observation, or making up a design you are trying to illustrate?
You draw the front and establish the height of the object and its placement in relation to your eye level and then use that to set its vanishing points for the other sides. Or you can use a plan view to establish its shape and height and pick where you want the vanishing points to go.
