In this video, I will show you how to draw intersecting objects using constructive drawing principles. Such principles greatly help to make realistic artworks especially when drawing from imagination. Here are some of my sketches. I do them to keep my drawing skills sharp and to teach my art students constructive drawing.

Keep watching this video till the end, where I’ll show you the low-polygon paper models of a skull, head and hand that you can make at home and draw from life. These models are available free of charge to the Life Drawing Academy students who take our personal tutoring.

As a fine artist, you may be interested in drawing portraits and figures, but figurative drawing skills greatly depend on your understanding of constructive drawing.

Here’s one of my sketchbooks with more than 80 drawings that were done in one month. All these sketches are made from imagination. I just take simple geometric solids like cones, cylinders, prisms and similar objects and arrange them so they intersect each other. I find it very interesting to draw simple things and see how their shapes interlock.

Of course, to make such sketches, I have to use the rules of perspective and other principles of constructive drawing. One of such principles is that all objects have to be depicted as if they are fully transparent. It is like drawing objects that are made of wire and completely see-though. It is called wireframe drawing.

There is one know-how of how to draw a perfect ellipse that was developed by me. I have not seen such method anywhere else. I teach it, among many other drawing techniques, in the Life Drawing Academy Correspondence Course.

I will now do a simple sketch to demonstrate how to intersect two rectangular prisms. I will draw the first prism in two-point perspective. Because it is a fast sketch, I won’t be worrying about precision of vanishing lines, although there is a special know-how of how to draw a perfect cuboid in perspective. I depicted this prism as if it is fully transparent.

To highlight the visible edges, I will outline them in pen and ink. This is totally optional. You can do the same in graphite pencil, making visible edges bolder and darker. Such approach is also one of constructive drawing principles – using the aerial perspective to create an illusion of depth.

Drawing in pen and ink is actually harder because you cannot erase wrong lines. If you make a mistake, that it, you have a line that is challenging to remove. Also, when drawing in pencil, it is easier to make the aerial perspective more convicting. Nevertheless, for the demonstration purposes, I will do it in ink.

To describe the geometry of these two intersecting prisms, I will suggest their tonal values in fast pencil hatching. Erasing invisible lines is optional. I just slightly clean up this sketch.

I developed one know-how of drawing a perfect ellipse freehand, but to keep things simple, I will draw it approximately, measuring its curvature by eye. If you would like to learn the know-how of constructive drawing, you are welcome to take the Life Drawing Academy personal tutoring course.

There is a way to ensure that different objects, like the cone and the prism in this example, are in the same perspective. I teach this method to the Life Drawing Academy Correspondence Course students.

In addition to these models, you will also get in-depth explanation of how to draw them step by step. Take the Life Drawing Academy personal tutoring course now - https://lifedrawing.academy/correspondence-course
