Drawings of the details are a technical document defining the dimensions of parts of products, design, technical specifications (TU) and processing methods. Patterns made according to the drawings, determine the precise on cutting.

The drawings are executed in pencil on thick paper or graph paper in scale of 1 : 1; for educational purposes is allowed on the drawing paper of the type Whatman scale 1 : 2.

All construction lines base grids and auxiliary lines perform thin lines (0.1 mm), contour curves details is performed first by hand thin dashed lines, and then encircle on the patterns. In practice of design and accuracy of calculations (if the construction drawings in scale 1 : 1) adopted within ±0.1 see

All the cut parts in the garment industry, on the accuracy of their implementation are divided into critical (tolerance on cuts is ±0.1 - 0.15 cm), less responsible (acceptable deviation by cross-section ±0.25 cm) and is not responsible (the permissible deviations according to slices ±0.4 cm). The magnitude of the permissible deviation for sections depends on the location of the seam in the product dimensions, the influence of the size and shape of cut on the quality of the product landing on the figure.

The cut parts outside the front side of the product, are more responsible than cut parts that are not visible when wearing the product. For example, the sections of the collar require a greater accuracy of registration than the internal section of podborta.

Cut parts of small size are more responsible than cut parts with large dimensions. For example, slices of leaves, the upper pockets are more responsible than the slices the edges of the side and bottom of the product.

Slices armholes, okatov sleeves, shoulder seams, neck affect fit (balance) of the product in the figure and are therefore within critical sections.

Sometimes critical sections (lapels, the end and departure of podvorotnya, etc.) deviate more established, if in the processing of products, they shall be further refinements in the utility templates - omelka and pruning.

The permissible deviations in sections of symmetrical parts is permitted in two times less than steel.

Acceptable deviation by cross-section curves should not exceed 25% of the value of the permissible deviation for sections cut out details.

In the drawings the details of the products put lines of prosanos, the bend of the lapel, the location of loops, pockets, tucks, control characters (radseck) denote the places of landing or stretching.

The design of the individual components and parts, if it has significant differences from standardized, imposed in the form of sections, sections, thumbnail images, etc. (Fig. V-38).

In the drawings, it is recommended to identify the main dimensions of the detail at the top or their parts, such as the length of the back and shelves, back width, armhole, shelves, distance between loops and their length, the position and length of the openings of the pockets, the length and sleeve width, and height of crown, etc. the detail Sizes put in centimeters. These dimensions are control and can be used in the preparation of the table of measures.

The ends of the Darts, pockets, undercuts, etc., ending inside parts, mark cross lines length 1 - 2 cm of the Notch is applied in two lines: one perpendicular to the cut length of 0.5 cm (the scale is 1 : 1) and the other a shorter, perpendicular to the first.

When entering one part to another, invisible slices in the drawing, denoted by dashed lines, and the visible slice is considered to be the cut having a more complex configuration, or constructed before the other.

Axial line in the drawings indicate the dash-dotted lines (middle of the back and front in products with a back and front, and lines of prosanos, etc.).

When outline drawings of the angles projecting to the outside of the parts, draw smooth curves (elbow sections of the sleeves to the elbow, medium cut backless shoulder blades, the side sections of the backrest and shelves, skirts and trousers to the hip line, etc.).

Especially carefully it is necessary to issue slices of Rostock on the back, slicers, stands and departures of podvorotnya. The lines of these sections is carried out perpendicular to the middle line details on the site at least 1.5 - 2.0 cm to obtain smooth contours of the parts after their connection.

In cuts and sections indicate the required dimensions.

All text and dimensions in drawings perform drafting font, pencil. Each drawing sheet must have the specification details made on the sheet.

Table V-6 lists the conventions that are recommended in the design drawings.
