For some, illustration is an art form, but for someone like me, it can be a nightmare! There was a time when I was hesitant to list “Illustration design” on my skills list. As time goes on, things get better and better. Fortunately, I managed to understand the science behind the art of illustration and now add the ability to “illustration design” to my list of skills. To be exact, I have the skills of equiaxial illustration 😃

I follow the wave of the home page of the personal introduction

In Part 1 of this series, I used the 2D illustration tool “Adobe Illustrator” to create step-by-step tutorials for equiaxed illustrations. By scaling, cutting and rotating orthogonal projections, we can simulate their isometric projections. You can also check out this article in this series: another dimension that 90% of illustrators don’t know about.

What is the second part?

In the first part, I demonstrated how to draw a cube using SSR. At first, orthogonal projection was drawn, and then SSR transformation formula was used to combine the deformed surfaces together to create an equiaxial illustration.

A note on the SSR formula in the previous article

Create an isoaxial illustration by combining the deformed surfaces together

But!

Now comes the important part! Not every object in the world is a cube. Not every object has 3 different sides. So what should we do when we encounter one of these objects?

Don’t worry, read on

Roll up the sleeve of this wit, and let me use this simple cylinder to demonstrate:

Before we start, let me tell you a little secret. It’s actually easier to draw an equiaxed cylinder than an equiaxed cube. I’m not bluking. 😊

Step 1: Draw the orthogonal projection

As I said in my last article, we first draw the top view, front view, and side view of the cylinder. Since this is a normal cylinder with a round top, the front and side views will be the same. I used different colors to distinguish them.

Orthogonal projection (top view, front view and side view of cylinder)

Step 2: Apply SSR formula to top view

Select the top view:

1. Scale the height to 86.602% (yes, exactly 86.602%, don’t round to 86 or 90)

2. Next, cut the scaled surface diagonally by + 30°

3. Finally, rotate the scaled and beveled surfaces by -30°

The deformation process of the orthotopic view

Okay, we’re ready for the isoaxial top view!

Next (prude 2333~), we switch front view and side view.

You don’t need to convert any extra faces! I said, this is much easier than the cube, that’s what I meant!

Why not do SSR deformation on other surfaces?

The cube you see, the bottom of the isoaxial view (hidden from view) is actually the same as the top of the isoaxial view. We never draw the underside, because it’s never redundant. When we assemble the front, side and other axial views, the underside is formed automatically (the underside remains invisible at all times).

Here are the images for your reference:

Now, in the same way, when we place top and bottom equiaxial surfaces, the corresponding front and side surfaces are automatically formed. This is especially useful in objects that don’t have sharp edges (sharp edges distinguish the front from the side), like this cylinder.

Only the top and bottom of the equal-axis illustration are equal-axis planes

In these equiaxial shapes, I used the pen tool to complete the “combined front and side view” (much easier than using SSR formula conversion!).

Step 3: Final assembly and recolor

Simply make a copy of the top view and move it down to get the length of the cylinder; Then draw a rectangle to fill the space between the two faces. And you’re done!

For a final touch, recolor the base and rectangle with the same shadows… Put the top surface above the other two layers.

Okay, you’ve drawn an equiaxial cylinder. Yeah! (Applause!)

Well, it’s not over yet…

If I don’t teach something more complex, I can’t even use the word “mastery”! (Well, if you use the same technique, of course)

How about this coffee cup down here? Why don’t we just draw it?

A cup of coffee

Yes, we absolutely have to draw this thing, but if we keep writing this article, it’s going to take forever! My guess is that when an article is longer than 10,000 words, you don’t want to read it anymore.

So, I decided to describe in detail how to draw the coffee cup in part 3 of this series. Be sure to check it out. In the meantime, if you’re not familiar with the SSR formula, go back to the first article in this series. 😛
