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 ->

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.

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.

If you want to learn more about what you did, search for tilted planes in perspective

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 ->

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.

Ellipse Master Template

Ellipse Master Template

This recommendation is really just for those of you who've reached lesson 6 and onwards.

I haven't found the actual brand you buy to matter much, so you may want to shop around. This one is a "master" template, which will give you a broad range of ellipse degrees and sizes (this one ranges between 0.25 inches and 1.5 inches), and is a good place to start. You may end up finding that this range limits the kinds of ellipses you draw, forcing you to work within those bounds, but it may still be worth it as full sets of ellipse guides can run you quite a bit more, simply due to the sizes and degrees that need to be covered.

No matter which brand of ellipse guide you decide to pick up, make sure they have little markings for the minor axes.
