I'm an illustrator newbie. I'm using snap to grid, which may or may not matter. When I draw a new rectangle and drag a corner, I see the length and width. But I'd like to see the length and width AND the position of the corner that I'm drawing. Is that possible? I think it is possible in Photoshop.
Not to my knowledge. The only thing similar I can think of is to make two guides, one horizontal one vertical and drag them from the crossing point. That will give you the current coordinates and the width and height of the dragging motion from starting point to the current location. Depending on what you are doing that may or may not be helpful.
Do you mean as you draw it? If that's the case then it's not possible, but if you type "A" right after you draw it you can see the coordinates on the Control bar and if you change the reference point you will see the coordinates for that point.
