This was so hard!

I feel I still need more practice with these.

If you have any suggestions at all, or revision requests, I will gladly accept them.

Congrats on finishing lesson 7, I'll do my best to give you useful feedback so that you can improve!

Jumping right in with your form intersections, you're off to a great start. Your intersections themselves look good - you've got a wide variety of intersections at play, and each of them demonstrate clear consideration to how the individual surfaces are intersecting, and how those pieces are stitched together at each transitional corner between the surfaces. From the flat-on-flat, flat-on-round, and round-on-round, everything is looking good.

For your cylinders in boxes, it's kinda hard to tell but I from what I can see you are also doing a good job here as well. It looks like you've applied the error checking method correctly. But I can see some hesitation in your ellipses / box lines, so make sure you're ghosting and drawing confidently from the shoulder.

For your vehicle form intersections you've done more than what was asked for but generally have stuck to simple forms which is good. This exercise is just taking the form intersections exercise and simply arranging those simple primitives into the layout of a car, so as to remind us that what we're working with are not individual, separate edges, laid out along a grid within our bounding box, but complete primitive forms, constructed as full volumes and not individual components stitched together.

Finally your vehicle constructions which is the real meat of this lesson are done pretty well, though there is more that could be done mainly for your orthographic plans. To demonstrate how we can get more out of these plans I'll use your McLaren as an example. If we take a look at this orthographic plan I've marked out areas which aren't really defined at all and seem to be based purely on observation. So while you have made the plans they don't actually help you much when you actually go to construct the vehicle. This is how you would go to actually define specific points on the vehicle beforehand which can then be transferred onto the 3d construction. You may think this is a huge pain in the ass and you're right. You might also think "is it necessary to go that far?" and it absolutely is because it allows us to make decisions before actually constructing the vehicle which allows us to fully focus on constructing the vehicle instead of thinking about where / how to place a side mirror or where to draw this curve etc. By tackling the problem 1 step at a time we can fully solve it easier and learn more from doing so.

Also there's a couple points I want to make about curves as I notice you've used them a lot.

  • The first point is in regards to handling curving structures. As explained here in Lesson 6, it helps a great deal to treat all your curves as though they're simplified down into a chain of flat lines or surfaces, effectively leaving the curving aspect out of it entirely. Some shallower curves can be represented with one line/flat plane (like the windshield), whereas others might need to be broken up into a couple or more (like the rear window). This way we can build our construction more solidly first, then round them out later. All things considered though, your grasp of 3D space is strong enough that your curves didn't fall into the trap of being too vague or unclear and effectively undermining that solidity. All the same, it's still something to be aware of.

  • You'll also notice that as a result of breaking the curves down into straighter chains, we end up with some clearer landmarks which we can then position at specific points along the length of a given dimension - so for example, we know that the very top of the windshield, where it meets the roof of the car, is positioned right at the 1/2 way mark along the length of the car. You did identify these landmarks for most such major points, which is great because it means that they can then be transferred to your 3D structure - but I would strongly recommend actually placing those landmarks by using the diagonal subdivision technique. Reason being, if the process we use in our 2D orthographic plans is the same we use when transferring it to 3D, there's less chance for information to be lost in translation. It becomes a matter of simply repeating the same process.

Despite this your work is fantastic and shows you understand 3D space well. I won't give you any revisions but if you decide to do this exercise again I would try to use as many construction lines on the orthographic plans to meticulously place each detail of the vehicle so that you can easily replicate it to the 3D construction. This will make it easier to draw and will grow your understanding of 3D space more. If you want a good example of this you can take a look at this student's work. Now in sharing this, the point is not to compare yourself to them but to look at their work and see just how far this can be taken in terms of decision making in the orthographic plans. You could even go beyond this if you wanted.

Either way you've done a great job and congrats on completing drawabox!

One Eternity Later:

Hi, I have a new construction!

It made my brain hurt and took so much time I'd rather not think about it.

Here it is before I go insane.

Very well done!

You've demonstrated an extreme amount of patience and dedication and have shown you understand the lesson perfectly. There is honestly not much to critique!

Good job!

Thank you so much for taking a look, and suggesting I do this!

I must admit, although it made me very frustrated, I've learned a lot trying to draw this properly!

Thank you so much for your critique!

I will try to do a couple of constructions taking what you’ve said into consideration. I will post them here when I finish, but it will probably take a while haha!

See you then, cheers!

The recommendation below is an advertisement. Most of the links here are part of Amazon's affiliate program (unless otherwise stated), which helps support this website. It's also more than that - it's a hand-picked recommendation of something I've used myself. If you're interested, here is a full list.


This is another one of those things that aren't sold through Amazon, so I don't get a commission on it - but it's just too good to leave out. PureRef is a fantastic piece of software that is both Windows and Mac compatible. It's used for collecting reference and compiling them into a moodboard. You can move them around freely, have them automatically arranged, zoom in/out and even scale/flip/rotate images as you please. If needed, you can also add little text notes.

When starting on a project, I'll often open it up and start dragging reference images off the internet onto the board. When I'm done, I'll save out a '.pur' file, which embeds all the images. They can get pretty big, but are way more convenient than hauling around folders full of separate images.

Did I mention you can get it for free? The developer allows you to pay whatever amount you want for it. They recommend $5, but they'll allow you to take it for nothing. Really though, with software this versatile and polished, you really should throw them a few bucks if you pick it up. It's more than worth it.
