Need advice for 250 cylinder challenge

6:21 PM, Monday February 6th 2023

Hello to everyone. Started my second part on 250 cylinder challenge, where you need to draw cylinders inside of a box. And my first boxes are incorrect, so it is impossible to draw correct cylinder in that shape. But my confusion starts when I need to make error checking. I don't understand how to draw "correct" minor axis in those wrong shapes (it is marked with red color). Can someone explain or maybe show some examples? I would like to ask that to one of the mentors, but can't find any way to reach them.

Here is first page of cylinders in the boxes - https://imgur.com/a/GwIsEwV

My humble advice would be that you spend a little more time analyzing and studying these 3D models and start with simpler boxes, with a simpler perspective, get them right, feel more comfortable with them first then move on to add the cylinder. Pay more attention to the overall construction of the box first. Looking and understanding the planes of the boxes is helping me understand the cylinder too. Well, at least this has been of a great help for me :) I hope it can help you in any way too.

Thanks, didn't think of using 3D renders as visual reference.

You're welcome, it is important to force our lazy brains to understand what we are doing wrong and ponder about it, but I also think it's nice to look, study, analyze some 3D objects, somehow by doing that I noticed I started to rotate objects in my mind with much more ease. Happy studies :D

It's no different from what's asked of you in the rest of the course - you do your best to follow the instructions, and nothing more.

You can rest assured that the boxes being "wrong" is not a problem for the exercise. If anything, it's kind of the point. The cylinders themselves are more part of the error analysis (like the line extensions), and they help us to identify where our boxes' proportions were off, so that in the next page you can make adjustments to how you draw your boxes to bring those line extensions closer together. This is mentioned in the cylinder challenge video, where we're looking at applying the line extensions and how we use them.

Okay, need to revisit my 250 box challenge, take a look at those boxes. I thought that cylinder is main part of this exercise, maybe that was my mistake. Wrong focus. Thanks for your 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.
