In this exercise, we're just going to get used to the concept of a vanishing point and plotting lines back to them to create boxes. We'll be drawing in 2 point perspective, and we'll be doing everything in this exercise with a ruler.
This process has a lot of steps, but each step is quite simple. Follow the instructions exactly as they're written, and you'll do fine.
)
Start by drawing a frame on your page - this is going to define the picture plane for our scene. You can think of this frame as being a window into a larger 3D world. Since we'll do this exercise several times on a page, make sure you arrange it so you can fit two or three of these on the page, and make sure they're rectangular, wider than they are tall.
)
Lay out your horizon line, and place your vanishing points on either side of it. You can actually place these vanishing points outside of the frame if you wish, but that's not necessary. Just make sure there's a lot of room between them, as you'll be working in the space in between.
)
We're going to be using 2 point perspective for all of these boxes. (REMEMBER: the fact that we're using the same vanishing points for all the boxes in this scene is not natural, and is only for the purposes of this exercise), as described in the "simplified" explanation at the end of the boxes lesson page. The viewer will be oriented towards a vertical edge of each of these boxes.
So, we're going to start drawing our first box by drawing a vertical line. Vertical lines in 2 point perspective run perpendicular to the horizon. Since our horizon is perfectly horizontal, then our line can be perfectly vertical, running up and down. The size doesn't matter, but don't go making it too big. This will establish the height of our resulting box.
)
Now draw a line back from each end of that vertical line back to each vanishing point. You'll be drawing four lines:
One from the top of the line to the left vanishing point
One from the top of the line to the right vanishing point
One from the bottom of the line to the left vanishing point
One from the bottom of the line to the right vanishing point
)
Now we're going to establish the width and depth of this box. We are NOT constructing a perfect cube, just an arbitrary box.
On the left side, you've got two lines going towards the left vanishing point. In the space between those two, draw a single vertical line. Then do the same on the right side, between those going towards the right vanishing point.
)
For each of these two new vertical lines, draw lines going from their tops and bottoms back to the other vanishing point - meaning, you'll be drawing 4 new lines, 2 to each vanishing point.
)
All that's left to do now is to draw the back vertical edge of your box. It can sometimes be a little tricky to see, but the two back corners of your box should already be defined where some of the lines you've drawn to your vanishing points intersect. Find those corners and draw your last vertical line between them.
I'll warn you now: This may not work perfectly. This kind of construction for boxes works assuming that every single step has been followed perfectly, without any human error. Every time you miss a vanishing point by so much as a millimeter, you throw things off by a little bit, and it accumulates.
That's totally okay, and if you look at any of my demonstrations, you'll see places where this back edge doesn't align quite right - but it's very close. There's really nothing to worry about there.
)
Lastly, you can add a little extra weight to the lines of the actual box by going over them with an additional pass. Do this with your same pen, and as with all of this exercise, use your ruler or straight edge.
You can put the most line weight/thickness on the lines defining the silhouette, a little less on the internal lines that point towards the viewer, and still less on the lines that'll sit on the opposite side of the form.
You can also choose one of the front-facing faces of the box and fill it with some tight, parallel, consistent hatching lines that stretch all the way across the plane from edge to edge. Don't rush this or do it sloppily - it's optional, so if you decide to do it, make sure it's neat and tidy.
This exercise is really only geared at familiarizing those who are starting out with the concept of a vanishing point, and how we can plot lines that are parallel in 3D space back to their shared vanishing points.
)
Sometimes students will accidentally draw their boxes so they sit - either entirely or partially - outside of the space between the two vanishing points. This can also happen if the boxes are placed too high above. I explain why this is happening in these notes on distortion and field of view.
Your results should look something like this.

This page has student-made readings/recordings
They can be helpful for those of you who cannot follow along with the text, or who need live examples for the exercises to follow along with.
Just keep in mind that as the lessons themselves are continually being updated and adjusted, the audio recordings may not be completely up to date.
Despite their age, Marshall Vandruff's videos on Linear Perspective are some of the best lectures on all the ins and outs of perspective, and as an instructor, he is highly respected across the board. He goes into a lot of the intricacies that I don't touch on in much depth (at least, not if I can help it).
On top of being some of the best, his lectures are also among the most accessible, at the full 8 hour set for $12.00. There's literally no reason not to grab them.
Having your work reviewed by others is critical, as those who are just starting out aren't in a position to properly judge their own work, and won't be for quite some time. Don't be afraid to show your struggles - it's by analyzing your mistakes that we can help you grow. Perfect homework is not what we're looking for; we just need it to be complete.
There are currently two places you can get your work critiqued by the community - Reddit and our Discord Chat Server.
Both of these are completely free.
If you are interested in receiving extra help, I critique the work of those who support Drawabox on Patreon.
All of these private critiques are done through reddit, in specific threads where students post their work as a comment, including a link to their work (often hosted on Imgur, though most image hosts are okay).
My requirements are more strict than the free community critiques:
The minimum pledge for this lesson is $5.00/month. The orange button above will take you to the reddit thread for this lesson, you can post a link to your work there and I'll be notified. Once I catch the submission, I'll add it to this backlog spreadsheet.
Pledges are collected at the beginning of the following month, but you may start submitting your work immediately. If you're a new patron, I'll be reaching out to your shortly to collect your reddit username.
