Drawing wheels on vehicles is an excellent way to practice cylinders and reinforce what we've already learned.
Level 1
Draw a simple car, bus, RV, or truck focusing on the wheels.
- Add a spare tire on the front or back to practice cylinders in different orientations.
- Use photos for inspiration, not for direct copying.
- Draw your vehicle from a slightly different angle than your reference to practice perspective construction.
- Make vehicles toy-like, simplifying details and focusing on perspective.
- Start with the side view silhouette in 3-point perspective, then extrude it.
- Construct wheels by approximating square planes and drawing ellipses within. Give them thickness!
- Experiment with the same vehicle from multiple angles or different types of vehicles.
Level 2
Include at least one tank in your drawings to practice cylinders along all three axes.
- Tanks should primarily be constructed out of boxes and cylinders.
- Add simple details like headlights, a window, or more guns for enhancement.
- Use the X method to ensure consistent wheel sizes.
General Tips
- Keep lines light and clean in early stages to avoid messiness.
- Apply "X-ray vision goggles" to visualize and construct internal parts.
- Remember the techniques for constructing cylinders inside boxes.
- Review previous lessons if necessary to refresh on the concepts.
Deadline: Submit by 03/28/2024 for a chance to be in the critique video!
Here are my Level 1 + 2 assignments. Another very useful learning exercise. I decided to skip the tank and punish myself with something with more circles and more persepective.
My assignment! I initially forgot to keep my lines perpendicular to the horizon line when constructing planes so I had made some wonky ellipses. I wasn't too happy with my first attempt (which was the car) so I attempted to practice with an oil truck since those have lots of cylinders.
Hopefully, one of the excellent Proko pros will come to your rescue but in case they miss your post - I also find this a bit of a mystery. From what I can tell, you've got the major axis correct (90 degrees from the minor (perspective line) axis. But, from what I can gather, the major axis just represents the longest part of the ellipse - it doesn't mean that the ellipse has to touch the edge of the imaginary box where it intersects with the major axis though. The ellipse needs to touch the edge of the imaginary box at the center of its four sides and just be a bit stretched out where it intersects the major axis. How stretched out it gets seems to be based on your feel for what looks right - which is where I get a bit lost. Anyway, I hope that makes some sense.
I redid this, I think I'm having a hard time eyeballing convergence angles. I get the concepts here, but I think I just need more practice making these angles more intuitive.

Yeah, as you practice you'll develop an intuitive eye for convergence. My only recommendation would be to make sure your circle touches all four of those points on the box. You did a good job finding the major & minor axes!
Two separate attempts plus a bonus cube just so I know I'm not going crazy.
For the life of me the wheels came out wonky EVERY time. I did these nice and slow, used lots of x-ray vision and measuring. It's just when I went to add the ovals for the wheels everything went off track. Especially when I tried to extend them to make them thicker. I think I'm just going to start doing a few of these as a warm up before every drawing session.
I just watched the demo and I think I see where I made mistakes. I'll redo these later today.
Level 1 and 2 wheels on vehicles assignment. After a handful of attempts I felt more comfortable with working through the process but I feel I’m still missing something… Looking forward to seeing the demo and sorting it out.
I didn't understand how to add the major and minor axis of the ellipse when you actually start constructing it in the boxes... The lines are a bit messy, but it looks, decent I guess? Anyways... I'll be very grateful for any critique...
A lot of work, lots of re-do, some clearly off the mark lines but Im happy with my airplane. Now that I get that out of my system Im gonna try the level one and the tank.
This type of work, with so many intersections, for me at least, to be well done needs a grid and a ruler... the airplane I just used the grid to see my mistakes and a ruler to make some final details. Now I did the F1 car with a ruler and grid and just by that I was able to detiver the final draw...
Spent ages on this with many attempts and have come to the conclusion that I need to spend ages more.
Definitely got a bit messy with the construction lines. I'm finding that I'm encountering a lot of trouble finding the major axis, any tips for that would be appreciated. I'm also struggling to make upwards facing cylinders like on the van at the top of my drawing.
https://www.proko.com/s/fbTg Not sure if this link will work, but Johannes S. posted a link to a very brief animation in the previous session that shows what happens with the major axis as perspective changes and you might find that helpful. I think for the level of drawing we're doing in this course, we just need to guesstimate the amount of offset from the center of the ellipse (Z/minor-axis) and it should be good enough, as long as the major-axis runs 90-degrees across it. For the upwards facing cylinders, have you tried rotating your page so it just becomes another sidewards-facing "wheel" that you're drawing? I invariably end up spinning my paper like a DJ trying to get whatever I'm trying to draw into the optimal angle for my limited abilities. Hope that helps!

A lovely pink tank ❤️
The ellipses look great!
Cylinders are really hard for me. Every time I think, I finally figured it out, the next one really sucks..
