In your “Actions” menu, under “Canvas”, you can add a drawing guide to your canvas. These are lines that will not appear in your final image, but will help you create drawings that are perfectly measured or centered.
After adding the guide, click “Edit drawing guide” to change the shape, opacity, colour, thickness or style of your grid – you can even make a grid that is isometric, or use the perspective setting to create accurate three-dimensional artwork.
