Advice 1: How to make patterns

Patterns necessary for the manufacture of clothing, footwear or soft toys. Of course, you can make a pattern and once. But if you intend to sew constantly, do this, which can be used constantly. This is especially important if you are going to do modeling. Patterns need a more durable material than the tracing or graph paper.
How to make patterns
You will need
  • - tracing;
  • - graph paper;
  • thin, but firm cardboard;
  • - plastic film;
  • - paraplan;
  • - copy paper;
  • - needle;
  • - ball point pen;
  • - dressmaker pins;
  • - scissors;
  • - boot knife;
  • - flat Board.
Move or build a pattern. It is possible to pick any fashion magazine or find on the Internet. If necessary, increase it. If you do not find anything suitable, sacrifice something of the old, but the right clothes. Strut it by the seam and trim to size. The undercut also strut. Cut them do not have can be transferred to the mold in another way.
Very often the patterns are made from cardboard. Pick up a sheet of large format. Put on it the pattern and trace with a ballpoint pen on a path. Cut out the pattern. If the pattern you are using an item of fabric and it has undercut, they also need to be translated. Place the undercut pin pins tailor's carbon paper so that the coloring layer is not in contact with tissue. Place the item on the template, carefully aligning the contours. You can also hold them together with pins. The blueprint needs to touch the patterns. Draw a circle around the recess and cut her.
The undercut can be translated in another way. Immediately after you will turn the edges of the product, prick the outline of the recess with a thick needle or awl, needle felting and fabric, and cardboard. The holes should be at a distance of 0.3-0.5 cm from each other. Remove the detail of the fabric, trace the groove of a ballpoint pen and cut out the pattern.
If you have nowhere to store patterns out of cardboard, make them out of more plastic material. For example, polyethylene film. Film select transparent, but dense, kind of what the cover of the greenhouse. In this case it is possible not to transfer the pattern from the magazine on tracing paper, and draw it directly into the polyethylene with a ballpoint pen and then cut. Such patterns can be stored in collapsed form even in a very small box.
You can make patterns out of thin paraplane. The order of operation is the same as with the cardboard. Cut better with a sharp knife, putting paraplan on a flat large Board. It is necessary that the knife was perfectly vertical, otherwise when cutting you will get error. Such patterns can be stored rolled-up.
If at hand are no large sheets of cardboard, glue together a few small. This must be done before you begin to draw the pattern. Glue the leaves are either overlapping or staple them together at the butt tape. In the second case the pattern will be convenient to take shape.

Advice 2: What is the pattern

One who is engaged in different types of modeling, often requires you to draw the same detail. Using a template can greatly facilitate the work. Such a template is called template. This is especially important if you have to draw the complex curves consisting of several fragments of different geometric shapes.
Pattern designed for sketching curves

What are the patterns?

In the drawing case, two types of curves – constant and variable curvature. The first is a template that may be as a complex curve, or more. The pattern of the second type looks like a ruler, to which is attached a special device which you can use to change the curvature. Patterns of both types are used, for example, in the garment industry. A vivid example of the pattern of constant curvature – the most common pattern.

In addition, there are view patterns, which are applied to control circuits of various components, if these contours have a complex curvature. This pattern is called measurement. The controller determines the amount of clearance between the work piece and a measuring template. In some cases, a special probe.

So-called sloping curve used in construction for laying of roads. With it, control the transverse profiles of the ditches and outfall ditches. This pattern looks like a triangle, consisting of the slats. Straps are at a certain angle to each other. This pattern requires that the cell and the drainage system met the standards.

Why do we need pattern?

In an era when many kinds of design done on a computer using software, sometimes it seems that the patterns become outmoded. But this is not so. They are constantly used in manufacturing to cut or carve intricate details, which there are sections of spirals, hyperbole and parabolas. The mold itself can be built with the help of a computer program and then cut from plastic or metal. In modern factories the patterns are made using precise methods, e.g., laser cut.

How to make patterns

To make curves using a variety of materials. For example, in the modeling of the clothes this can be paper or cardboard, in school lessons of drawing used plastic patterns, and to control the curvature of parts of machines used most often metal or durable plastic.

To build a simple mold you can and do. Take a sheet of paper, draw on it a circle. At some distance, draw a circle of a different diameter. Connect both pieces of the two tangent. Cut what you get. In this case, the full circle was even excessive to build simple patterns enough to know the location of several most important points.

How to draw with templates?

To draw a curve on a curve, select the desired area. Define three points. Find out on the curve appropriate curve and draw it as you do, when you use the ordinary drawing with a ruler.
