![]() The vertical lines from the side view are extended to make the long sides, then reference the front view to determine the length of the sides and draw connecting lines to complete the rectangle shape of the top view. A couple of center lines will help keep the location of the terminals correct (these represent the centers of the terminals, not the rectangle).ĭrawing a top view will use construction lines as well. For the battery, that would be the terminals on top. Next, add whatever other features can be seen from that point of view. If you try to draw a rounded rectangle in one continuous stroke, you're going to end up with a potato. Draw straight lines, then rounded corners or vice versa. To draw a rectangle with rounded corners (also called fillets in designer speak), it's important to draw the parts individually. In the case of the battery, that's the rectangular profile of the front. It's often helpful to use tick marks as targets.īefore going any further with construction lines, draw the primary shape of the object from one viewing angle. Remember to draw parallel lines first, then draw the crossing lines do get proper right angles. ![]() Try to get the proportions as close to the real object as possible by using your fingers or your pencil to get a rough idea. Start by drawing a few construction lines to create boundaries for the different views of the object. ![]() Think of construction lines as a kind of cage that your drawings a built from. You can never have too many construction lines, especially if they're drawn lightly in pencil. They help to tell you where hard lines (lines made in pen) should go, and help you make sure things have the right proportions, help you make circles and other complex shapes, and keep different views consistent. This is why it’s important to start with 2D drawing before moving onto 3D.Ĭonstruction lines are a great tool to control your drawings. Trying to design exclusively in 3D (whether by sketching or using 3D software) can often result in objects that aren't well thought-out, as you need to see how each side relates to the other. By drawing the object from different points of view in this way, we are able to make decisions and solve problems in a localized way. If you look straight-on at any side of the box, what you see of the object inside is its orthographic projection. To create an orthographic drawing, imagine that the object you want to draw is inside a glass box. This kind of drawing is not done using perspective. The top, front, back, left side, right side, and bottom are separate sketches. Simply put, this means drawing an object straight-on from each of its sides. The way to break down a design and study it is to use orthographic projection. This is as true in math and history as it is in music and design. To understand something complex, you have to look at it in pieces. Seeing the projected sides of an object helps us understand proportions, scale, and relationships that are difficult to see in 3D. When developing a design through sketching, it helps to look at the object in separate “orthographic” views, also known as multi-view drawing.
