Art varies as much as nature itself. Mediums exist in different formats, from colourful oil paints to fine and concise charcoal pencils. The subject of artwork varies just as extensively; some art is abstract, while other art attempts to mimic real life. Isometric drawing falls into the category of realistic perspective, taking into account the point of view of shapes and objects.
Start Simple with Shapes
Most beginners start with very simple shapes. A box is a suitable starting point. To create a box, draw a simple square first. Taking into account perspective, extend three parallel lines from three corners of the box outward in the same direction. Two connecting lines, matching the shape of the original square, will connect the extending three lines to form the final three-dimensional cube. You can create a triangular solid with the same technique. Cylinders are even easier, as they require two circles connected by only two lines on the outermost points of the circles.
Use Your Eyesight
To begin to draw isometric drawings, you need to understand eyesight. When viewing objects, take a close look at the direction of lines. Look at a box and you will see a three-dimensional shape; however, determine which way the lines point; these directions will help you understand your final goal when attempting isometric drawings. You'll notice three surfaces, each forming varying shapes. Sets of lines will be parallel. When you move to a different angle, everything will shift. Observe your natural surroundings carefully to view the isometrics of real life.
Create Vanishing Points
One of the common techniques for drawing isometric cityscapes or rooms is creating vanishing points on the paper. Pick a horizontal line along your drawing paper about three-fourths of the way up the page and draw a solid line (which you will erase later). The rest of the page will consist of only vertical lines and lines that disappear into the two vanishing points. To test it, draw a cube in the centre of the page. Create the vertical lines; then when creating the rest of the lines, connect them to the appropriate vanishing points. When you make new buildings or shapes on the page, connecting them to the same vanishing points will ensure everything on the page is in perspective in relation to other objects.
Make Friends with Your Eraser and Ruler
If you want to draw isometric drawings, you'll want to become best friends with your eraser and ruler. To avoid confusion, as well as when working with vanishing points, you will often need to create lines which you will later want to erase to avoid confusion. An example includes using vanishing points. When connecting shapes to a vanishing point, beginners will often draw lines all the way across the page; however, once the shape is created, to clear up room, you can erase the excess lines. Even the vanishing points themselves are only temporary. Rulers are key in making sure everything is in line. If edges lose their sharpness, images can very quickly lose their effect.
