Handling the back corner of perspective boxes

1:39 AM, Thursday December 24th 2020

I'm working my way through the 250 box challenge. One problem I've started to run into a lot is that my back edge doesn't fit - I understand this is the accumulation of errors. It's actually gotten worse - part of me thinks that as I've gotten more accurate, the errors I make don't cancel each other out as much.

What can I do to overcome this?

From the challenge page:

You may find it difficult to do so, and may find that often times the "back corner" fails to fit with the rest. This is completely normal. As we draw a box, we regularly make small mistakes in our angles and trajectories of our edges. We compensate for them as we continue to build out our box. This accumulation of mistakes always falls on the lines that have yet to be drawn, and if we're not drawing through them, it becomes quite easy to get by without having to deal with the issues present. Once we draw that back corner however, we're forced to come to terms with our blunders.

Yeah, the back edge is a pain! I started trying a different step orders when drawing boxes halfway through the challenge and doing boxes this way: https://imgur.com/a/LThxTqI was the most effective for me. By doing the back corner early in the construction It becomes easier and I always leave the most foreshortened side of the box for last since it's the one that requires the most accuracy and having the back edge already drawn helps.

Thanks, I'll try that out! When you say "most foreshortened", do you mean the sides with the closest or the furthest vanishing point?

I mean the narrowest side, the one of which you can see less. It's usually the side closest to the horizon line or to a vanishing point. Good luck with your practice!

Here's a link that might help: https://discordapp.com/channels/365036548820959242/365180330103013388/783038487716429864

It is pretty similar to the other reply.

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.
