## it this possible?

Hi fellow box designers, I have a point-blank question for you.

During my 250 boxes challenge I ended up in a situation several times that I'm not sure is possible:

2 lateral vanishing points downwards and the 3' always downwards in the same direction. To help you understand I have attached a drawing -> https://imgur.com/a/RboGZsj

Is this situation possible? Or conceptually wrong?

It isn't possible for a normal box. You're getting this in this case because the form you have is more of a trapazoidal shape, making it seem like there's a vanishing point on the bottom. If this were a box and all the lines converged properly that vertical vanishing point would be on top.

exactly!

Its not a cube.

In this case, there is no 90 degree relation between the lines on corners.

The box you drew is much larger on top than in bottom in a way that even if it's moving up away from the picture plane it's still visually bigger than the bottom.

I think It is possible, every line goes to its own vanishing point, so conceptually I guess it is right, though I'm not an expert, but if i put a boc on a glass table and you look from under the table It could be possible to be accurate this box

Ok, I thought about it again... and I think it's conceptually wrong..

If the 2 lateral vanishing points go downwards it means that I am looking at the box from the bottom upwards, because my horizon line (my eyes) are under the box. So if I look up, the 3rd vanishing point can't point towards the horizon but away from it.

As before, maybe I'll explain better with a drawing -> https://imgur.com/a/gpKtTlc

did I get it right?

Wow that was getting into eating my brain, but i suppouse that you're right, I had done many isometric and 3D draws for my carreer but I have never seen one like the left one and thinking about it you're right, but I feel I had seen that in a draw before, felt like a building falling over you, so I don't really know, but if I had to choose I think that yes, the left one is conceptually wrong...

That moved my ground, I'm going to ask a around, if I have news I'll comment in here

It's not an impossible 3D form. It's just much bigger on top than bottom, creating the visual effect.

The planes on the sides are tilted.

### Pentel Pocket Brush Pen

This is a remarkable little pen. I'm especially fond of this one for sketching and playing around with, and it's what I used for the notorious "Mr. Monkey Business" video from Lesson 0. It's incredibly difficult to draw with (especially at first) due to how much your stroke varies based on how much pressure you apply, and how you use it - but at the same time despite this frustration, it's also incredibly fun.

Moreover, due to the challenge of its use, it teaches you a lot about the nuances of one's stroke. These are the kinds of skills that one can carry over to standard felt tip pens, as well as to digital media. Really great for doodling and just enjoying yourself.

I would not recommend this for Drawabox - we use brush pens for filling in shadow shapes, and you do not need a pen this fancy for that. If you do purchase it, save it for drawing outside of the course.
