To draw our cross contours on the cylinder, we need to establish the centre line or axis. Let's start by looking at what direction the cylinder is pointing. Cross-contour lines will be perpendicular to the axis the form takes Imagine that your line goes through the surface across to the other side.ģ. We need to imagine the form as transparent and draw through it. This line also looks wrong because it is too shallow. Some beginners might then try to create a curve without understanding its reasoning. With straight lines, the cylinder looks flat. Let's try the same thing with a cylinder. Imagine the form as transparent and draw through it The last drawing looks like a ball and is much more convincing than the others.Ģ. What if we drew curved lines? This makes it look like a curved dish.īut when we curve the lines across the form, we can create the illusion of a sphere with just a few lines. Let's take a circle and draw straight contour lines. While most of us might think that a banana is cylindrical, we might notice that it actually has flat edges when we draw cross-contour lines. Regardless of the media you choose - pen, pencil, brush or digital tablet.Ĭross contours don't have to be obvious - they indicate the direction and the imagination fills in the rest. These concepts are necessary for drawing and painting to help you make decisions regarding the direction of your stroke. Why are contours and cross-contours important? But a book will have a flat surface.Īnother common way to understand contour lines is to see them as changes in elevation, like on a topographical map. To help you grasp this idea, take your finger and slowly trace a path across the surface of an object.Ī cup will have a rounded surface along the body. These lines convey three-dimensional depth, length, width, space, distance and perspective.Ĭross contours can be both horizontal and vertical, like the latitudes and longitudes on a globe. Cross-contour lines may or may not be visible on the subject but describe the form. To give these mushrooms more dimensionality, we need to add cross contours.Ĭross-contour lines are lines that cross the form of your subject, as the name implies. Once we add the inner contour lines, the drawing makes more sense. Not all contours exist along the edges of a subject it includes changes of plane within the form. We need to add some inner contour lines to help us understand what we see better. In this drawing, we can see the contours of the mushroom, but it still looks flat. Contours are used to depict the mass and volume using simple lines. The focus of contour drawing is the outlined shape of the subject rather than the details. You can modify a subject's form with variations in the lines to depict objects realistically. The line is one of the most critical elements of art, not excluding colour, shape, form, texture, value and space. Back then, I had no idea that I was learning important skills in using lines to improve the design of my drawings. These books are often just designed with varying lines. When I was a child, I enjoyed reading comics. Simple shapes and lines can bring a story and its characters alive. I have always been fascinated by how a few lines could describe forms. It helped me visualise objects and understand how they related to the space they occupied, so I had to share it with you. I had no idea that using simple lines could alter your drawing and make it look much more accurate. Are you struggling to get your drawings to seem convincing? Contour drawing changed how I drew for the better and improved my artwork tremendously.
