How to calculate the radius and draw a circle without a circular.

comment 5 comments

Good afternoon, dear novice seamless self-taught. Today I decided to write an article that would help us in the future to cut children's panamas, adult beach hats, as well as the Sun skirt, and naturally the swiss. As you guessed, we are talking about the ability to calculate the roundabout radius, and you will be able to draw it without a circulation. Because it is possible that we need to draw a circle of this size for which the circuses are not sold. Yes, and not all at home has a circulation.

So, on the agenda the following:

• Calculation of the circle radius, for Panama, Vacan and Sun skirts.
• Three ways to draw a circle without a circulation.

How to calculate the radius of the circle.

Why is it needed, this calculation of the radius? To draw a circle, we need to know radius This soma is circumference - that is, the distance from one feet of the circulation to the other.

Suppose we need to draw a circumference of the Panamka Panamka, and all that we know is the scourge of the baby's head. How do you need to push the feet of the circulation widely to get a circle that coincides with the sizes of the baby?

Or we need to draw the circumference of the Sun skirt, knowing only that the length of the circle must ideally coincide with the girth of our waist.

Now that everything is extremely clear and understandable, we will analyze 2 specific cases that are most often found in the work of Shvent.

This is the calculation of the radius of Panamki. And the calculation of the radius on the pattern of the Sun skirt.

So let's go ...

I painted this story beautifully in pictures directly with the text-inspection. So that the whole sequence of brain work is clear.)))

It means to find out the radius - we need our scum of the baby's head to divide by 6.28.

We take a mobile phone, we find a calculator in it and divide our 42 cm of scuffing of the head to 6.28 - we get 6.68 cm \u003d that is, 6 cm and 6 mm. This is a radius.

So we need to push the feet of the circulation to a distance of 6 cm 6 mm. And then the circle drawn by us will be 42 cm - that is, it will fall like a smoothly on the child's head (just do not forget it will break down by 1 cm for points on the seams).

The situation is the second - you need to draw the Sun skirt circumference. All that we know is the waist girth and the length of the skirt that we eventually want to get.

In the drawing of the Sun skirt there are 2 circles. Little (internal) should lie down Rovenko on our waist. That is, the length of this circle must coincide with the waist girth. Cooking waist 70 cm, it means that the circumference of the circle should be 70 cm (well, except that there are all sorts of centimeters there and here in the form of an allowance for the seams, or what additional finish in the form of a belt or coquette)

So we need to know what radius to draw a circle to ensure that the circle is resulting in length in these necessary us70 cm.

In the picture below, I did everything and how to calculate the radius of a small circle and how to learn the radius of a large circle.

And when the small circle is drawn. All that we need is to a small radius add the desired skirt length - and we get a large radius for a large circumference of the edge of the skirt.

With the calculations we figured out. We will sew skirts and panamans - I will send you to this article.

Now let's figure out how to draw a circle of any size without a circular.

How to draw a circle without a circulation.

Here, I illustrated three ways for three pictures. I hope that everything is clearly painted and spelled out.

Yes, this is a quick way - but it is necessary to ensure that the pencils do not spoke to the side. The angle of inclination of the pencil change the radius. Or it is necessary that one person smoothly holding one pencil, and the other exactly perpendicular to the second pencil.

Actually, the lower the thread is tied, the more accurate will be a circle. Therefore, some use small pins. The error with the deviation of the pin to the side is small, and when it is sewing it can be printed.

And yet, the most reluctant way to draw an accurate circle without a circulation, it is with the help of a conventional line and pencil. Here's what it looks like:

And then in a circle, move the centimeter (as a watch arrow in the clock) and mark points at the same distance - that is, on the same digit of centimeter tape. Instead of a ribbon, you can use the twin with a marker applied on it - the main thing is to make sure that the twelley does not stretch at all.

Well, that's all - another gap in knowledge eliminated - now it is possible to turn on the skirt-sun and we can count on the panama - we can count the radii. It's only the beginning! Soon we will so wonder that without fear we will take for the most complex models. Here you still tell you about the volani and about the pattern - the foundation - yes - yes, we draw a real adult pattern with you in 30 minutes - and as they say, it started ... We will sew everything in a row))). And not only .

Drawing a circle is not the most common task in life. The hard to come together with thoughts when you have to draw a circle of hand, without a circulation, stencil and other auxiliary devices. But no one is immune from such a need. Someone more often, and some less often, draw a circle without a circulation happens to everyone. Schoolchildren and students who have forgotten at home is ready. Parents of preschoolers who adore cut "skirts" for cardboard dolls. Parents of schoolchildren who receive homework make paper snowflakes. Housewives, regularly in the bottom of the baking form suitable in size with a culinary parchment.

At home, draw a flat circle easily: you take a plate, saucer or glass, put upside down on paper and drive around the contour. What about drawing the perfect circle of hand? We argue, the circle will rather rather on oval, ellipse or polygon, depending on the accuracy of your coordination of movements? In the end, this is already challenge yourself. Will I make such a trifle how to draw the perfect circle without a circulation?! We know: you can. If you take strain and use a few tricks that allow you to draw a flat circle without a circulation and / or a stencil, by hand.

How is the easiest way to draw a circle without a circulation?
Forgetfulness - not trouble, if you can compensate for its resourcefulness. Suppose you left the Circula houses, going to the geometry lesson (just on the topic associated with circles) or a meeting (you need to urgently draw a visual circular diagram). To nobody guess about your scattering, did not put a twice or did not reprimand, we offer you such simple ways to draw a circle without a circulation:

• In the penalty (your or neighbor on the desk), take the transport. This drawing tool is famous for versatility: often replaces the ruler, and in the absence of a circulation, it will also perform its task. Put the transportation on paper by placing the middle of it to the smooth side to the point that will become the center of the future circle. Holding the transportation with his left hand, circle it with a rounded part of the pencil - it is half a circle. Now carefully not to shift the center of the circle, turn the shipping around the middle of the middle of 90 °. Again, circle the rounded side in a new place. Turn the shipping on paper to complete the circle and bring the pencil line to the complete circle. In principle, you can draw a circle of two semicircles, but not all transporters allow it, so the method of three steps is considered the most versatile and accurate.
  
• If there were no transportation nearby nearby, you will have to violate the reputation of a diligent student and take advantage of the subject, approved by all teachers: a CD. The manager at the meeting will be easier, because at hand, there will be a disc with a presentation or photographs from a recent corporate party. Put the disk on paper and, pressing with your left hand, pass the pencil right. If necessary, draw a small circle, circle the disc is not outside, but by the inner hole.
  
• Draw from hand circle for chart in the abstract simplest simple! To do this, take the ordinary glass (glass or plastic disposable - does not matter), pretend what you want to wash the throat. Pour into a glass of water (it will make it harder and more stable), make sure that the bottom is dry outside, and put it on a sheet of paper lying in front of you on the table. Now carelessly, not attracting excessive attention and without making sudden movements, outlines the bottom of the glass on paper. Spee a sip again and put the glass away from the paper.
  

Circul, CD and a glass - the most common objects in the offices, but you can use other rounded circuits to draw a circle without a circulation. The only drawback of this girlfriend is in a limited radius of the obtained circles.

How without a circulation draw circles of different sizes?
To draw different circumference without a circulation smoothly and beautiful, you will have to do without auxiliary means: only paper, pencil and dexterity of your hands. But do not be afraid: it is hands that the circle is able to draw a circle without a circulation. With these methods you can take advantage of almost in any situation:

1. To draw a small circle from hand, and literally, put a sheet of paper on the table or other smooth horizontal surface, and take the pencil to the right hand in the usual movement. Run your hand with a pencil to paper and, a little not until the end, lowering the stylus on the sheet, mind the little finger in paper. The main condition: the little finger should press the sheet to the table securely, but allow it to rotate around the axis, which became the point of contact with the pillows of your mother's. Put the tip of the pencil on the paper and fix the position of the brush. The second hand rotate a sheet of paper around the Misina axis - and you will see how the stylus outlines the perfect circle around it. A pair of advice: it is more convenient to use a soft pencil (in or 2b) and briefly crop your nails.
   
2. To draw a smooth circle with a larger diameter, you will not need other devices, in addition to those listed in the previous paragraph. Similarly, take a pencil with a sufficiently soft blade with your fingers right. Mysinetty this time bend and press to the palm of your face as if your fingers were collected in a fist. Enroll on the bow of the Misina and repeat the previous reception. Rotate a sheet of paper at hand and fixed with a pencil with a comfortable speed to get a neat circle. Manicure in this case no longer plays a big role. You can draw the circle of medium sized without a circulation separately, and you can around the already drawn small circle.
   
3. To draw a circle of a larger diameter, you can get along with your own hands. The scheme of action is repeated as accuracy until the fingertips are bent. But this time, I do not rest on the knuckles, but on the protruding part of the wrist. Outside there is a protruding bone, which will serve perfectly supporting the hand when drawing a circle. Hold the brush and pencil in it by fixed, turning the sheet of paper on which a smooth circle of the desired size will appear.
   

The greatest complexity of the described methods is to learn not to move the right hand holding a pencil. But you will probably handle after a few workouts and / or pick up a suitable speed of the sheet of paper under the griffel. In any case, artists admit that we use this particular technology when you need to draw the perfect circle of hand.

How to draw a big smooth circle without a circulation?
Schoolchildren, artists and office employees are a little easier: their circles are placed on a small format paper. But tailor and cutters have to work with more extensive surfaces, and the circles in their activities are not less common. Rounds of Panamocks and hats, Sarafan Podols and skirts - the basis of all these silhouettes is a circle. But this circumference is often such that there simply does not exist proportionate to it. And here's how the seamstresses came up with draw circles without a circulation:

1. To begin with, determine which circle to draw from hand - that is, the radius of this circle. For this, a regular centimeter ribbon make measurements of the desired area: waist gripping, head circle or other parameter. Suppose it is a waist girth 60 cm.
   
2. The resulting number is the length of the circle. To find out the length of the circle's radius, use the arithmetic formula: R \u003d circle length / 2π. Accordingly, the radius of our circle will be 60/2 * 3.14 \u003d 60 / 6.28 ≈ 9.5 (cm). This is the radius of the circle that we have to draw by hand.
   
3. Take two pencils of the same length. Tie them a durable thread, the length of which without taking into account the nodes (that is, the actual distance between the pencils with a stretched thread) is 9.5 cm. One pencil set in the center of the future circle, and the second swell on the length of the thread.
   
4. Holding the first pencil stationary, the second wrap in a circle, drawing a trace of the griffel on paper and keeping the same thread tension over the entire process of drawing a circle.
   
5. Thus, we simulated the principle of the circulation, without having a circulation for drawing a large circle. The drawn circle is perfectly smooth and can serve for the pattern of the skirt belt.
   

To draw the full pattern of the skirt, increase the radius (the length of the thread between the pencils) on the estimated length of the finished product and draw the second round around the first. Before you the workpiece of the Sun of the Glush Sunshine, which you drew without the help of a circulation and even a stencil.

How to draw the perfect circle without a circulation
The main and, possibly, the only drawback of all the methods presented above is the flaws of the drawdered circle. Drawn without a circular circle is obtained approximately smooth, but not entirely perfect, especially if it is drawn in a hurry. There is a way to fix this trouble. It will take a little longer, but will delight the result:

1. Take a sheet of paper, pencil and ruler.
   
2. Take a decision, what will be the radius of the future circle.
   
3. Put a point on the paper sheet and attach to it the "0" mark on the line.
   
4. Put the second point on paper. Accurate near the figure, meaning the radius you selected.
   
5. Move the ruler, apply "0" again to the starting point and put the second point in accordance with the radius length.
   
6. Continue to put points at an equal distance from the center of the future circle.
   
7. As a result of these actions, you must get a circle drawn by dotted line.
   
8. The more points you put, the point will be the dotted line and less the distance between its risks.
   
9. Connect the circle on the dotted.
   

These are simple and affordable ways to draw a circle without a circulation. Choose any of them or use suitable by circumstances. And remember that there are no hopeless situations - you can always come up with how to get out how to solve the problem or even draw a smooth circle of hand without a circulation. Good luck, beautiful drawings and perfect graphs! 1 vote

Good day, dear readers. Something for a long time I did not write the lessons on Photoshop. It is necessary to urgently correct. Today we will talk about one very simple thing, which will be useful for both in or other elements for sites and just for beautiful pictures and postcards.

Now you will learn how to draw a circle in Photoshop. It is very simple, quickly and interesting. I will also show you some interesting options for making your own modern materials for the site, posts for groups in social networks or just postcards that will not be ashamed to send to friends.

How to draw simple, smooth and beautiful circles

First of all, you need to open the Photoshop program. Do not forget that you have the opportunity to use the online version pixlr.com. .

I do not get talked to say that you should not pay attention to simple (or other) options like Paint or some more nonsense. Learn to work in professional programs.

Now read the article about solving one task, tomorrow about the other and in a year you can perform very healthy projects, even if they were not at all going to do this. Put in front of the global goals. But, back to the main topic.

Create a new document.

Suppose it will be in the amount of 500 x 500 pixels. It does not matter.

Now we find the Ellipse tool in the control panel. If you can't find it right away, try to hold the mouse button on the left and press for a few seconds. Perhaps the ellipse is hidden under the rectangle.

Now draw a circle.

So that the circle turns out even clamp the SHIFT button on the keyboard. It helps to keep the proportions.

After you finish, you will get out an additional control panel. It duplicates the one that is at the top of the screen. You can work in anyone like more, it does not matter.

If you need to draw the figure of the desired diameter, change these values \u200b\u200bto the necessary parameters. Let it be 500. See if you have only one indicator for some incomprehensible reason, do not forget to change the second, and then draw an ellipse.

You can use a gradient, pattern or choose one color. Open the optional panels to expand your own capabilities.

Here you can also use different techniques: gradient, pattern, one color or without stroke.

If you want to change the line itself, look at the following graph.

By the way, I completely forgot to say if you use a gradient for pouring, then try the radial effect so that the color goes from the center.

Another interesting effect

You can draw a circle directly in the picture or move it to a photo using the Ctrl + C buttons and Ctrl + V (Paste).

Now work with opacity (in the panel on the left). See that the panel is highlighted exactly the layer with which you are working. In this case, the ellipse.

In the circle you can write some text.

If difficulties occur, you can download the PSD layout of this picture, which you see in the screenshot above, and digging in it. So learning more interesting. Observe my example on your own. It is not at all difficult. ( Download \u003e\u003e )

There are layers: photography of savanna (background), there is a circle with a gradient (ellipse 1) and text. If you download this file, you can open it and you need to help Photoshop, and then have fun as you want.

Or another picture you can download ( Download \u003e\u003e ).

To create it, in addition to those moments that you already know, on each layer I pressed the right mouse button and changed the overlay parameters.

Download this layout and see yourself, maybe you can significantly improve the result! Feel free and leave your options in the comments.

For those who want to comprehend

If you and my lessons, I advise you to subscribe to the newsletter of my blog and receive information about the latest interesting publications to make money. It is really convenient.

However, agree to learn and become a professional will have to wait a lot. After all, besides Photoshop, I tell about the WordPress, how to sell and create sites, about plugins and negotiating with customers.

If you want to learn photoshop in order to create sites, I can recommend two more options. The first - lessons here is from here - " Web design for beginners" I wrote in detail about them. In principle, if you want, you can learn a lot for free, for three days, which are provided as a test period. Very helpful and great.

However, it is cool if you learn for yourself. If you are interested in earnings in large, then pay attention to the netology, namely this course - " Web designer: Efficient site from idea to implementation »:

Yes, the price, of course, bites.

But what program and which teachers are waiting for you.

Here you and the director of Red Keds, and the creator of interfaces from Kaspersky Lab, and also a bunch of eminent and successful guys from world-famous companies. At the end, you get a diploma. This is really expensive.

That's it. Now you know the maximum and I can decorate with a calm soul.

Good luck in job!

Dear novice seamstress self-taught, today I decided to write an article that will help us in the future to cover children's panamas, adult beach hats, as well as the Sun skirt, and naturally flowns. As you guessed, we are talking about the ability to calculate the roundabout radius, and you will be able to draw it without a circulation.

And when the small circle is drawn. All that we need is to a small radius add the desired skirt length - and we get a large radius for a large circumference of the edge of the skirt.

With the calculations we figured out. We will sew skirts and panamans - I will send you to this article.

Now let's figure out how to draw a circle of any size without a circular.

Olga Klishevskaya, especially for the "Women's Conversations" site.

Any line, any barcode should express in the figure a certain form. Thanks to the strokes, lines are applied, which, in turn, create depict various figures. Flat shape figures have a straightforward surface characterized by only two measurements - length and width.

The square is the right polygon, the four sides of which are equal, and all four corners are straight. Square to draw a pencil on a small sheet of paper is easy, you only need to have a hard and confident hand. It is much more difficult to achieve confidence when drawing a square in a large drawing. In a similar case, coal is considered the most suitable drawing tool. Calculate the size of the square, you should portray one vertical side. Now, from the top point of this straight line, it is required to carry out the perpendicular line of the same length. From the right point of this second line, read the line, perpendicular to it and parallel to the first. And finally, it is required to combine the extreme points of two parallel lines.

On the following scheme, the scheme showed two squares, one more (external), another smaller (internal). On the axes of the symmetry of a large square are eight reference points. The peaks of a small square are at a distance of two thirds of the diagonals of a large square from its center. The peaks of a small square are combined with smooth arcs, so the circle is formed.

1. In order to draw a square, you need to know the length of it.

2. From the top point of the vertical straight line, mark the line, perpendicular to the first and equal length.

3. Repeat a similar action, finding another top point of the square.

4. Finish the creation of a square by connecting parallel direct.

Rectangle

The rectangle is the right polygon, the opposite sides of which are equal, and all the angles are direct. When creating a rectangle, it is necessary to perform the same actions as when an image of a square, but considering at the same time considering the difference in the ratio of the parties.

A circle

When creating a drawing, an indispensable tool, no doubt, is a circulation. In the picture, it is extremely important to learn to draw without it. As long as the skill is not formed to portray the range of the right hand shape, it is allowed to use some of the remedies, for example, pamal or, as an improvised circulation, even a conventional cord. To achieve the goal, you can also note the reference points on two concentric squares.

How to draw a circle of hand

In order to learn how to draw a circle of hand, you should start training, creating small circles with a radius of about 5 cm. As a rule, first the figures obtain several oval shapes, then, as practical experience gains, circles gain the right outline. To draw larger circles, it is advisable to outline on two concentric squares of the reference points or use the cord in order to facilitate the task.

When creating drawings, use the cigrough is not recommended.

Practical advice: how to draw a circle with a cord

To work out the skill of creating the correct large circle, it is useful to use the cord.

1. One hand hold the tip of the cord at the point that will become the center of the circle. In the other hand, hold a piece of chalk and the second end of the cord at a distance, which is equal to the radius of the circle.

2. Start drawing an arc from the point that allows you to perform the maximum wide movement chalk.

3. To close the circle, the hand in which the chalk is held, skip the cord at hand. At the same time, a hand with a chalk in the opposite direction.

4. Make sure that the cord is retained at the same distance from the center of the circle, achieve an accurate connection of the start of the second semicircle with the end of the first.

The circle is also drawn with the help of globes. The simplest lecturer can serve as the top of the glass.
