Form Intersections

4:43 PM, Thursday December 3rd 2020

Uncomfortable says that form intersections take a lot of time and work to understand, is anyone else completely confused about how these forms intersect? (I of course mean beginners.) And also what can I do to understand it?

You need to look at the shapes that you have drawn and then use your imagination and visualisation skills to see how they interact ( there can be more than one possibility ) if they were 3d objects. Then you simply need to draw what you see in your brain over the top.

Of course it's the development of the imagination and visualisation skills that takes the time and what you are really working on here. A lot of the time you kinda guess and then check if it looks right. Over time your abilities become more intuitive.

You can create a 3D model to clear your doubts about how a certain volume intersects with another. If you want you can check my intersections library on Sketchup's 3D Warehouse:

Thank you so much for sharing! This is very helpful indeed. I think more people need to know about the work you've done on creating the intersections library, because this topic can be rather mind-blowing. Especially if you don't have any reference images. I myself struggle with intersections a lot, especially when there are two rounded objects (like a cone and a cylinder) intersecting with each other, since they are rounded this particular instance leaves me so confused. Thanks a lot again.

Thanks for sharing. That is very helpful with respect to understanding the concept.

Pentel Pocket Brush Pen

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.
