How to draw a perfect circle without a compass. How to draw an arbitrary circle or an even circle in Photoshop

Thanks to the ability to draw a perfectly even circle, you can learn to draw many other objects. For example, you can draw a ball, a ball, the sun, and many other things on a piece of paper. In order for the circle to be even, you need to use a compass, which is one of the most important geometric tools.

Constructing a circle

Before you draw a circle, you need to take the necessary items. To do this you will need a ruler, compass, pencil and notebook. To draw a perfectly even circle, you need to know some of the nuances of its construction. First, you need to mark the center of the circle on paper. The center is the point where the compass needle will be installed. In addition, points located on the boundary of the circle will be equidistant from the center. This distance by which the boundary points are removed from the center of the circle is called the radius.

The radius size is set by the legs of the compass. To build a circle, you can simply move the legs of the tool at any angle, but so that it is convenient to draw. If a specific radius is specified, then you need to place the leg with the needle on the zero mark of the ruler, and the second leg on the required number.

Before you can draw a perfect circle, you need to understand how to use a compass. To do this, place the needle in the center of the circle, and grab the top of the tool with your thumb and forefinger. Under no circumstances should you grasp the legs, since when the compass rotates, you can move them, which will lead to a change in the figure. After this, you need to carefully rotate the compass until the boundaries are closed. These boundaries left by the compass lead will be the contours of the circle. You can shade the entire area inside the circle with a pencil to create a circle.

Constructing a circle without a compass

Many novice artists are tormented by the problem of how to draw a circle without a compass using auxiliary objects. There's really nothing complicated about it. To do this, you need to arm yourself with a ruler, a pencil and your own eye.

First you need to draw the coordinate axes to get the center of the circle. The center of the circle will be located at the point of intersection of the axes of symmetry. Now, using a ruler, you need to lay out identical segments from the center of the circle in all directions, which will be the radius of the circle. After this, you need to carefully connect the points with a smooth line to get a circle.

To understand how to draw a circle isometrically, you need to remember that isometric projection creates a slight tilt for all shapes. This is why a circle in isometric projection takes the shape of an oval. To construct such a figure you will need a pencil, a compass, a square and a protractor.

How to draw an even circle without a compass?

You can take a pin. Tie a thread to it on one side, and on the other, tie a pencil at the required distance (radius). Place the pin in the center of the future circle. And holding the pencil strictly vertically, draw a circle. In this way you can draw fairly large circles.

When I was at school and when I didn’t always have a compass at hand, I often resorted to a simple method. He took a pencil and, for example, a pen that does not write and will not leave a dot in the center of the circle, in one hand, squeezed it approximately the way the Chinese hold chopsticks when eating, and simply rotated a sheet of paper or notebook. The result was an almost perfect circle. Maybe that’s why, when I picked up chopsticks for the first time, they told me that I had been using them all my life anyway. Here's the story.

The easiest way to draw a circle is using any round-shaped object. for example plates, coins and so on, you just need to circle this item. You can also use a stencil and find a circle of the diameter you need.

But when my compass broke, and there was nowhere to get it in the evening, but I needed to build, I took a simple pencil, drew serifs on the nm with a pin, as if depicting a radius. And I went to draw from the intended center at certain intervals of about 10-15 degrees , and putting down points, at the end of the radius pencil there will be points on the circle. And how many there will be, how much patience you have. It helped so as not to grab a couple, the circle was drawn, and the problem was solved. Why didn’t you use round glasses? They were too big for a notebook, but There were no such coins; 5 kopecks were too small.

Without a compass, a circle can be drawn evenly using some round object; a glass, mug, tube of cream, etc. are suitable for this.

You can also take paper or cardboard, fold it 4 times and cut a semicircle around the edge. When you unfold the paper, you will get a circle. Circle it and that's it.

There are several options: you can find some object with a round bottom (a cap from a pill, nasal drops) and trace it around the bottom with a pencil. You can take a ruler, make the center of a circle and measure even distances from this center, then connect the dots.

It depends on how big you need to draw a circle.

If it’s small, then a coin, button, or tablet will do.

If it is larger, then you will need a glass, plate, pan, lid, cream jar.

You can also use a pushpin, to which you tie a thread of the required length and a pencil or chalk to the other end of the thread. Stick the button into a sheet of paper and draw - you will get an even circle if the thread tension is uniform.

Use something round of suitable diameter, a saucer, a mug, or another object on which you can draw a circle. Well, circle this item accordingly. This will create a straight line. Only in this case, if the diameter is important, then it may be difficult to select an item. There are also special rulers-patterns. There are usually several circles of different diameters. If you have such rulers, you can use them.

And I usually take into account the cells from a notebook for mathematics, adhere to even symmetry, etch the dots, and then smoothly draw a circle along them, they always drew like that before at school...)) Didn’t you draw like that yourself?..)

Drawing circles of various diameters is far from the most necessary skill in life. However, sooner or later the need to draw a circle without a compass and other round-shaped auxiliary objects takes everyone by surprise. Therefore, it is better to find out in advance without a compass, regardless of its diameter.

How to draw an even circle without using a compass

You can be a schoolchild who came to a geometry lesson, forgetting his drawing tools, a student, an adult forced to draw a perfectly straight circle - different situations happen.

It will be useful for every person to know how to draw an even circle without a compass. We offer you several ways to solve this problem.

A compass can easily be replaced by another tool found in every student’s pencil case, namely a protractor. Place it on paper, marking the central point on the straight part, this will be the center of the future circle. Trace the inside of the semicircle, then rotate the ruler about ninety degrees and draw a third of the circle. Rotate the protractor one more time and complete the circle.

If you're in a meeting or at work and don't have the tool you need on hand, just use the CD. Trace it from the outside or from the inside to get a smaller shape.

In an office setting, you can also use a glass. To do this, take a glass of water, take a sip and place it on a sheet of paper, lightly circle the bottom. Drink some more and set it aside.

All of the above items can be found in any office; the protractor will also be available to students. With their help you can draw a circle evenly without a compass.

Draw circles of different sizes without auxiliary objects

What to do if you need to draw circles of different diameters?

It is not at all difficult to cope with this problem, having only paper and a simple pencil on hand.

Take a pencil in one hand and place the other on a piece of paper. Place the little finger of your first hand on the sheet so that it is the center of the future circle. Hold this position well. With your other hand, start turning the paper around your little finger. You will see how a smooth circle is obtained, just like when using a compass.

A larger circle is drawn in the same way, but in this case bend your little finger, as if you were clenching all your fingers into a fist. With your left hand, start turning the sheet until you see the resulting circle. It is advisable to use a pencil with a soft lead.

A circle with an even larger diameter can be drawn by repeating all the above tips, but now the right hand should touch the sheet with the protruding bone on the wrist.

These are the simplest methods on how to draw a circle without a compass. The most important thing in these methods is to learn to keep your right hand motionless (left if you are left-handed).

How to Draw a Perfect Circle Using a Ruler

If you have a regular ruler on hand, then you can use another tip on how to draw a circle without a compass. Take a ruler and place it on the paper, the "0" mark will be the center of the circle, so place it in the right place. Draw the second point near the digital value corresponding to the radius of the circle. Move the second edge of the ruler slightly so that the middle remains at zero, and the third point is located slightly above the second.

Do this procedure several times. As a result, you should have a circle drawn. The more often the dotted lines, the easier it will be to connect everything into a solid line.

This is perhaps the easiest, but at the same time the longest way to draw a circle without a compass.

The question is important not only for beginners, but sometimes also for experienced artists. Understanding how to draw a circle correctly in perspective, we can draw a huge number of objects, not just pots and plates.
In general, a short summary: usually we rarely see round objects from the front. For example a plate like this

We see much less often than this.

Therefore, we need to understand how to correctly depict a plate in a perspective horizontal plane. There is a simple diagram for this.

The most important thing is on the left. We see ovals and the horizon line, relative to which we usually draw all objects. At the level of the horizon line, the oval either turns into a line or becomes very narrow. The higher or lower, the rounder the oval becomes, all the lines that are closer to us according to the law of perspective will be thicker, everything further away will be thinner. If the oval is much lower than the level of vision, it can become almost round. This can be seen very clearly by taking a roll of tape, your ideal medium for practicing this skill. We raise the skein to eye level - ideally we will see a rectangle, raise it higher and lower and immediately see clearly all the changes.
In the vertical plane, the story is absolutely the same, only the diagram must be turned 90 degrees.

Thus, all plates and pots become subject to us, we look at the previous picture of the plate, taking into account new knowledge.

You can draw another oval to show the thickness of the plate, the final result depends on your observation skills. The skill of drawing ovals is very well trained in detailed drawing of simple objects; the same roll of tape, for example, works great at first.

There is another common mistake when drawing ovals. Many people draw two arcs instead of an oval. This should not be allowed, even if your oval is very narrow; we always draw roundings in the corners.

Over time, you will become great at finding perspective in almost any object.

Well, after you get tired of circles, you can try drawing squares - the principle is the same. There is indeed a nuance with the vanishing point, but more on that another time.

I hope you no longer have problems with the circle in perspective and your drawings will be correct and accurate. In addition to this post, you can also see
