Drawing an oval with a compass and no string (very simple)
HTML-код
- Опубликовано: 9 авг 2012
- This is an easy method for drawing a general-purpose oval shape. This method requires you change your compass setting 3 times, thus, 1-2-3. If the first setting has radius 1, the second setting has radius 2, and the third setting has radius 3. The largest circle is tangent to both of the smaller circles at the same time, and so it becomes difficult to discern where the curve changes from one circle to the other (after the construction lines have been removed). We are pattern recognizing machines, and so our eyes are quickly fooled into seeing an oval, rather than seeing the intersection of four circles. A similar technique may be used to draw an egg, by changing the size of one of the two smaller circles. Based on the relative popularity of this video, I may make an egg-tutorial in the future.
By the way, this is not actually a true ellipse. If you would like to see how to make one of those, follow the link at the end of this video.

This is a brilliant method. It is by far the easiest and straight forward than the first 4 videos I have watched. 10 out of 10.
Oh wow! Been breaking my neck trying different ways. You did it so simple and explained nicely. A big thank you! Gratitude and love ❤️
Sorry to disappoint, but a true ellipse is too complex to be drawn with a fixed-radius compass. The mechanism you are looking for is called the 'trammel of Archimedes.' Conveniently, I also have a video about that. I will post a link to it at the end of this video.
Thanks!
Thanks, was wondering about that. I'm using it for a one off sign so it is good and easy enough.
@@SanDiegoArtNut Yeah but for most purposes this will do. You really only need a perfect or true elipse in mathematics.
Thank you for this. Very clear instructions. Needed a cardboard template for a wall sculpture. This was perfect!
the ending of step two looks strangely like Garfield the cat... lol great vid, keep em coming
OMG YOU MADE MY LIFE SO MUCH EASIER
Thanks, so simple yet such a big help!
Playin with the queen of hearts!
Brilliant!!! Thankyou so much for doing this video. You have added to the collective intelligence of artists and would-be artists.
Nice of you! If you're collecting such intelligence, then also try using differently sized circles. You'll get an egg ;)
Thanks, that has just made a difficult job very easy.
It is a very good method. It helped me alot as I was searching for it for many days. Thanx bro......
Thanks this is just what I need as I’m painting some 6mtr speed roundels on a road tomorrow.
Thank you, this is exactly what I needed for a Halloween costume I'm working on. The only problem I had was my ancient school compass was not big enough to reach on the last 2 steps. It worked ok to splice some pencils together. (-:
Next time use the string method, you can draw one as big as you like that way.
Your description is perfect for me !
Thanks Sir, If I hadn't seen this video I would have had a hard time drawing the epllise. I did not know that ellipse is so easy to draw.
Love From *INDIA*
Thank you - great demo ! :)
Thank you for giving a very simple way.
Thank you it helped me alot in making my project for preschool presentation
Very n8ce & simple method. Thank u so much.
It was so useful, thank you 😊
Great tutorial ! Thank you !!
Thanks for sharing. Just what I needed to create bulkheads/frames for a boat..
smashing stuff thank you!x
THANK YOU VERY MUCH FOR THE VIDEO. IT REALLY HELPED MR A LOT..
Nice and very easy method to make oval. Thanks ☺
Thank you so much ! You really help us with this tutorial
Lol
Thank for the help! Great music taste too!
Awesome video, thanks!
Thankyou! I needed this, and its easy.👌
Nice!
Just to get the precise start and end points of large arc in step 3:
1. Joining the center of the large arc to the center of smaller circle
2. Extend the line till it cuts the smaller circle at P
3. Do the same for the other small circle at Q
4. Draw the large arc from P to Q
Thank you very much for this easy solution of drawing oval😊
Awesome vid really helped out with my kids parade float
This was nice, any easy variables in this wonderfully simple method to make a different ratio oval? Thank you. Not to get the background song out of my head. :)
Thank you sensi
you are just awesome.
Awesome Video!
Haven't done geometry in 11 years. Thanks for the simple instructions!
great thanks so much .
Bravo et thanks a lot
Thank you very much
Thank you!
Easy and perfect oval
Thank you, solved my problem for diy project
Thank you
Thanks you very much sir please keep it up
Nice demo, thanks! I came here from "bullshit grinder" which most people say is completely useless, just meant as a joke. But it turns out to be a "trammel of archimedes" - a machine that will trace an ellipse. A mathematically proper one I think ( the maths is in wiki) . Of course a person has to decide whether it's worth bothering to make the machine! Pins and string are easier, but it's nice to see your compasses approximation, which could be the quickest in some circumstances. Cheers!
Double vision? Aka cock eyed
The bull is forgiveness
thank you!!
Thanks! We have to draw a cylinder and I don't have my oval stencil with me!
cool background music!
Thank you so much!!! The helped me so much making my plate😊 I had to search a tutorial because I didnt listen to my teach🥲
Well I just welded me a compass out of solid steel that is 20 inches long. With this technique, I can make a small table top out of metal or wood with this. Gonna get out me jig saw!
You could have done it with just a piece of string, look it up on YT.
What's the tune in the background?
Love it
thanks!
Hello, I was wondering what compass you used. Looks pretty heavy-duty.
Thanks
Thanks!
Hey, i have a transom window, and i want to cut a piece of plywood in a half oval that fills the window, any easy way to make it symmetrical and the highest point in the top middle of the window?
The oval shape in this video is NOT a true ellipse. If your transom window is elliptical, then you might want to try drawing the shape with a string and two nails. It's an easy procedure, but it's a bit difficult to explain here in a comment. Give it a search, and if you still have trouble, come back and get me.
Nice!!!
Hi'
I am trying to learn how to make perfect rings to a gas giant exoplanet I am oil painting.
Can you make a narrower elliptic shape with a compas too?
I saw the string method.
But I don't have the tools for that.
This "oval" is really just four tangent circles. For realism, you're probably after an _actual_ ellipse. To draw one of those, you will need to use a device. You can use something as simple as a string or as complex as a 'Trammel of Archimedes.'
An ellipse is a continuously changing curve, so it is not possible to draw one with a standard compass.
If you just want a 1-2-3 oval that's thinner at its minor axis, try playing around with three or four center circles, and see if you like how it looks.
As an artist, you might try sketching/modeling an ellipse by looking at a circle with one eye closed; as you begin to turn it flat, it will appear to pass through every possible elliptical shape.
Thanks
Wow 👌
Thumbs up buddy Thumbs up !
Brilliant! Just what I needed!
Awesome
Thanks a lot
Also the bg music was nice
Cheers m8
great
I like this. Im drawing 20' ellipses on a job, so i dont think this will work, but i like the idea
Wow. Well, for drawing an actual ellipse with a string, just remember this:
_the string is the length of the major axis._
@@pocket83squared oh sure, we do them all the time for work, i was trying to learn a new way though. 👍🏼
cool!
Needed an oval to make an address plaque, this worked perfect! Thanks for keeping this available all these years.
Nice👍
Useful
cool
Vary good
Looks like a family guy character.
❤
This method was uploaded when i was born
Thanks I like this video
me too
You broke my brain
Надо было для наглядности отметить точки сопряжения. А то не все могут понять где должны закончиться дуги
is it perfectly an oval? Or is it just a round figure looks like an oval?
The word oval is a general term for a curved elongated shape.
The oval shown is *not* an *ellipse,* if that's what you mean.
I am here after 10 years straight 😊
Thanks so much for sharing; Jesus Christ Bless you! :)
Someone's playing gta sa in the background
And, how can you say that?
This is the heart balloon the 3 horse was trying to hold on to from stopping it from falling. Aka eye within an eye
Simple......
I LOVE U BABY!
Legends are gonna listen to the background music very carefully 😂
It's not criticism, but I think that you may want to know how to create shapes more appealing to the eye as an art form to include into your projects.
And a heads up for that is B-Splines (NURBS) 3rd order most frequently with few control points (4), and few knots. If you are interested in this, research this on the web and find programs able to create B-splines (maya, alias autodesk, and other, yet it may sound an overkill to use such a program just for a B-spline)

EXACTLY WHAT I NEEDED!!
THANKS SOOOOOO MUCH FOR THE VID.
ALSO, GREAT QUALITY, BUT THE AUDIO CAN DO BETTER
Thanks. And I'll use my new camera if I ever go back to 2012 to make more videos.
What’s the point of the line?
Good enough for a picture frame, but still there is a key thing:
Some shapes are pleasant, some are not. Like sound and noise.
For that, a first thing to learn in a design (automotive) is to use very few vertices, preferably 3 for any given line on that car/object.
So.. in other words a NURBS curve 3rd degree will look good anyway. (because.. idk, just the same with sound, why a major scale sounds right but if misplaced a note sounds awful?)
Otherwise it is a solution for an "ugly" shape.
😂
that was an oval. it has to be a circle
Deec
Should be titled "How to draw the same pseudo-oval every time with only a compass"
"Oval" is a nondescript; the title does not claim to demonstrate how to draw a strict ellipse.
Most people clearly aren't as smart as you, so they can't tell the difference. But given your wit, you already know that it's not possible to use a fixed-radius compass to draw an infinitely variable elliptical curve.
The balls are vertical and tiny and light blue in colour in the thumbnail
It's vertical and dark? The tiny x is a tiny elf penis leak
Dont worry about the balls they have put the balls inside the aubergine to hide it and if they need to they can make the aubergine into a 8 as the llama goat nipple backfired 😭
Thanks commenter I can't remember what character you was then but really appreciate it 😂
My maths teachers and my engineering teachers at school used to throw a fit if we called it a 'ruler' "Oh? Of which country boy?!" For the pedants out there it's called a RULE.
That's pretty petty. But it's all about context. In an engineering class, extremely specific language is prudent.
unfortuanely i dont have a compass
