I had an interesting sensation when doing this. When the lines were light and I was just factoring in the curve sometimes the box would invert in my mind and i'd have to stare at it for a few seconds to make it flip back the other way. It stopped happening after i started putting down the colored lines but it was a weird phenomenon when the box was inverted, like my eyes could not figure out what I was looking at. Did anyone else experience this or should I go see a doctor? :D It was a good exercise and i had to fight my urge to just freehand the line when I didn't quite understand how the curve was working as it tapered in. Sometimes the taper would lessen or harshen the curve, which didn't look right until it did.

My second arrow turned better but incredible trick ! I started to understand how to project shapes from a cube to create more complex drawing (I think !)

Had to try this out and it was a lot easier than the twisting arrows. I even dared freehanding all the construction lines without different colors. Great exercise to teach the eye to "see" construction!

Loved playing with these too!

Curved arrows & curves in perspective – Love the exercise

I did not use different colors for each of the axes because… I guess I wanted the extra challenge of getting confused and to push through that!

Hey folks! I tried to draw a curved object from an ortho and thought it maybe worth to share?

The whole time you were twisting the arrow, the only thing I could think about was snakes.

It was cool to discover those 'hidden rectangles' in the Right-angle method. I wouldn't have thought of it like that, and found it a bit hard because there are so many construction lines that it gets confusing. Fortunately, after thinking for a long time, I managed to pull through. Although, I wanted to understand and engross the cross contours into my brain so much that I ended up drawing the hidden lines darker. Resulting in a lot of smudging... Apologies in advance. I would need to work on this in the future to draw construction lines and hidden lines more lightly. Also, my grandma says that all the arrows that we have been drawing lately look like seahorses. So here is a seahorse :) I tried to treat the tail like a curved arrow that converges and gets thinner from the body to the tip of the tail; I ...think... it looks right.

This was one of the most beautiful discoveries and adventures. Thank you so much.❤️

Curves going back and forth on the y and z axes aren't nearly as tricky as curving in and out along the x and z axes. Twisting also proves to be pretty difficult.

Love how well you dissect every process Marshall, so happy to have taken up this course! Here's my attempt at creating what I understood from this lesson. A few more manic lines for your enjoyment 😶‍🌫️

Followed the video. Great information. Never thought of it that way. did a couple. to make the technique clear in my head. hope it comes across clear on paper.

Some things clicked after this lesson - i) orthos are not just reference, you can use them as you draw to solve problems ii) building the box and scaffolding first is a very good idea before attempting curves iii) tracing paper is great for problem solving… As the penny dropped it gave confidence to try and solve a problem I’ve wondered about and tried to freehand intuitively with poor results; a hollow open canoe-like form in vertical perspective with a lot of foreshortening…so curves in perspective. Tried a simple oblique view first then tipped the canoe vertical for more extreme ~worms-eye view. Well, the results were a lot more successful than freehand intuition…! Also learned a pencil eraser works to remove ink on tracing paper. Useful stuff. 🤩

Thank you for the arrow and the thinking it creates, Marshall and blondie. I used the ellipse cheat for the violins as I did not know how else to curve that middle area. It's awesome to know it's a well established way.
