In another guide , you can find four exercises that help you move from two to three dimensions.

Here, we will focus on working with the primitive forms: the box, cylinder, sphere, cone, and pyramid, through exercises that help you become better at drawing them from imagination at any angle.

The box is often seen as the fundamental basic element when working in a three-dimensional space. If you can rotate a box and know how to draw things inside a rotated box, you can draw anything at any angle. In addition, you can build things from boxes.

To draw boxes well, it is important to make sure the ribs of the box go to one of three possible vanishing points.

A mistake beginners often make is to let the lines diverge from each other as they move into the distance when they should be converging. Another mistake is drawing edges that are too tilted. Be on the lookout for these two mistakes. See this 3D model for reference:

You can practice this by just filling a page with boxes of various sizes and orientations. It can help to look at a real box. For that, you can use a 3D model for reference.

It is also useful to practice randomly scattered boxes from a reference, for example, using the 3D model below for scattered random boxes.

If you draw random rotated boxes from imagination, you will initially draw them separately, isolated on the page. In this model you can see that they overlap. Practice using this 3D model to get a feel for what it looks like if boxes are spread randomly through space.

A good exercise is to draw a matrix of boxes, each rotated in controlled ways, to see if you can give each box an intended rotation. For example, draw a matrix of boxes that are slowly rotated around the x or z axis as they move along the x and y axes.

There is a 3D model also for that:

There is also a Perspective Drawing Game that lets you hone your intuition, your ability to freehand draw rotated boxes from imagination:

After learning to rotate a box, a next step can be to learn to stack rotated boxes.

You can also practice drawing stacked boxes using this 3D model to get a feel for how they would look.

A useful exercise is to draw boxes along a line:

It trains you to rotate the box in a controlled fashion while keeping its proportions the same.

There is also a 3D model that helps you practice drawing boxes that move along a line.

It trains you to rotate the cylinders in a controlled fashion while keeping its proportions the same.

As we gain control over our ability to draw boxes, it is useful to learn to use it to rotate other things inside. Here, we will place a cylinder inside the box.

Note also the use of the diagonal lines and construction lines to help construct the cylinder’s circle and ellipse caps.

You can practice drawing the circle and ellipse-shaped caps of the cylinders independently by using this 3D model:

And practice drawing cylinders in boxes from observation using 3D models:

We can practice that further by drawing a cylinder that moves along a line.

There is also a 3D model that allows you to see what it would look like, and helps you practice that:

Fill a page with the primitive forms — the box, sphere, cylinder, cone, and pyramid — rotated in various orientations.

You can also use the following 3D models to practice that:

This warm-up was inspired by Zefdraws .

Draw a box that rotates around one rib. Between this warm-up and warm-up 7, this one is easier.

A: Draw a through-line.

B: Draw a box that has one rib on the through-line. Make sure the other ribs that are parallel to that rib are also parallel to the through-line.

C: Add more boxes, rotated.

Tips On Drawing These Boxes

This 3D model was inspired by the excellent videos by @zefdraws . He also sells worksheets explaining how to draw these models.

Draw a center line, and then draw boxes that rotate around that line, with one rib of the box staying on that line.

Tip 1: Try drawing these from observation first by using the 3D models, so that you start to get a feel for what the shapes and sizes of the top plane that rotates look like. This will also help train yourself to draw them so that they appear equal in size.

Tip 2: Construction order.

Draw a center line. Draw the first box that is aligned against the center line.

Take one edge that is connected to the center line and is most visible after rotation for the box below the box you just drew. Determine the rotation and draw it. Then take the edge attached to it that is visible and in the same plane.

Close the top rectangle of that square. Draw the ribs that extend downward from the top plane, keeping them aligned with the other vertical lines that are parallel to the construction line. They should all be going to the same vanishing point.

Lastly, draw the ribs that delineate the bottom plane of the box, trying to make the box as equal in size as possible to the boxes you have already drawn.

Tip 3: It is relatively easy to draw the boxes so that they appear to be in the same perspective space. The main challenge will be to draw the boxes so that they look equal in size.

Tip 4: After you’ve practiced drawing this using the 3D model and gained a sense of understanding, try drawing these from imagination.

Tip 5: To learn to draw more accurate lines, you can try the dexterity warm-ups on the website.

You can use the 3D model below.

It is okay to draw with a pencil and eraser, but once you get the hang of this model, try drawing it directly with a pen. This forces you to be more intentional with every line.

It can be useful to practice drawing this from observation using a 3D model first, to see what these rotated boxes typically look like. You can find a 3D model for this here:

This warm-up was inspired by Zefdraws .

Draw a box that rotates around one rib. Between this warm-up and warm-up 7, this one is harder.

A: Draw a through-line and circles around the through-line.

B: Draw a box that aligns against the circles.

C: Draw similar boxes at different rotations.

Tips On Drawing These Boxes

This 3D model was inspired by the excellent videos by @zefdraws. He also sells worksheets explaining how to draw these models.

The ribs closest and farthest from that center line move along a circle, or an ellipse in perspective.

This is relatively hard to draw because you need to establish the ellipses that these ribs align with first, and ellipses are relatively hard to draw. Practice drawing ellipses first before attempting this model.

Draw the ellipses.

Draw the inner rib that aligns with the inner ellipse first.

Then draw the ribs radiating out, and draw the rib farthest. Make sure to keep in mind that these ribs need to go to a vanishing point.

Then draw the ribs that go down, also ensuring that these ribs, along with all the other vertical ribs of the other boxes, all converge at the same vanishing point.

Draw the face on the bottom of the box.

Repeat that for all the boxes.

One additional thing to pay attention to is making sure all the boxes are approximately equal in size. That is one thing you can train yourself to do while drawing this 3D model: ensure a box remains the same size as you draw it in different positions and rotations.

Practice by drawing it from observation of the 3D model first. You can do that by using the 3D model below.

After you get the hang of how this 3D model works, try to draw these from imagination.

It is okay to use a pencil and eraser for this model, at least to draw the ellipses that the boxes need to be aligned with. Drawing directly in pen can be done, but that is a bit advanced for this model.

This warm-up was inspired by a model someone requested. It is fun and easier than it looks.

Kim Jung Gi famously said he saw boxes, and people standing in them. It would thusly stand to reason that it is useful to practice drawing randomly oriented boxes on a floor!

That is what this warm-up is about: draw boxes on a floor.

This exercise is helpful in training you to move objects in space.
