DETAILED DESCRIPTION OF THE INVENTION

[0028] In FIG. 1 shows a general diagram of a method for designing garments 100.

At step 101, an automated garment design system receives a client request to create a garment.

The initial request may be a user registration in the system using the Internet browser of the computing device.

[0029] At step 102, the user of the system enters dimensional dimensions of the physique under which the manufacture of the garment will be carried out. In FIG. 2 shows an example of the selection of primary dimensional features. Characteristics can be entered by selecting features from the table of standardized sizes 201 or by entering the individual sizes of figure 202.

[0030] The user of the system can enter the required number of dimensional features for subsequent designing of clothing, in particular, height, chest circumference, girth of the chest area, waist, thigh and fullness of the thigh, as well as additional features.

[0031] At step 103 (Fig. 3), the user checks the correctness of the entered common dimensional features at step 102.

After the user sends dimensional characteristics for processing, a request is made to the database of dimensional characteristics 150. In the database 150, dimensional characteristics are recorded for 7 full-size groups for a wide range of growths. They are based on real measurements, statistically approximated, supplemented and expanded by a system by mathematical calculations and multiplying dimensional signs from neighboring dimensional groups (girls / women, boys / men) taking into account age-related changes in posture and soft tissues.

[0032] Initially, a set of existing standard shapes is selected that correspond to the leading dimensional features, among them, those that correspond to the complex of dimensional features are selected by the approximation method, if they fall between several typical shapes.

Empirical corrections are taken into account, for each amendment, the corresponding size attribute is adjusted in percentage terms. After this, the interdependent dimensional features are recalculated (lateral projections in case of changes in the frontal projections, and so on). When recalculating projections, girths are taken into account.

For example, when a user enters a hand length of 170 cm, the system will give an error, in the form:

Arm length = 170 (user specified)

System response: the specified size exceeds the statistical 2.27 times, it is recommended to clarify.

In the case of a size falling between typical figures, a complex of dimensional signs based on supporting bones and verticals is found by recalculating the dependencies in similar dimensions.

The girths are refined by mathematical methods (straight-line, curvilinear and cumulative correlation, empirical and theoretical regression based on the materials “Dimensional typology of the population with the basics of anatomy and R 17 morphology” / T.N. Dunaevskaya, E.B. Koblyakova, G.S. Ivleva, R.V. Ievleva), as well as on the 3D mannequin (clarification of the length of the broken line according to the leading frontal and lateral projections and girths along the soft tissues).

[0033] At step 104, a three-dimensional (3D) mannequin is constructed based on the entered dimensional features by the user and their additional verification.

An individual 3D mannequin is created by a series of calculations of dimensional characteristics of the user based on a database of dimensional characteristics of 150. Six dimensional groups are divided into the system, of which 5 are anthropological:

1) Women

2) Men

3) Infants (height up to 86 centimeters)

4) Girls (height from 86 centimeters to 188 centimeters)

5) Boys (height from 86 centimeters to 188 centimeters)

6) Dolls (an open size group for dolls that do not comply with standard anthropometric rules. For this group, you can only select the type of doll (Barbie) and build a mannequin on it. You cannot resize, make empirical corrections for this size group).

To calculate dimensional signs, it is necessary to introduce leading dimensional signs, which a person can measure with sufficient accuracy at home:

1. Growth

2. Bust

3. Girth under the chest (only for the female size group)

4. Waist

5. Thigh circumference excluding abdominal protrusion

Perhaps the introduction of additional dimensional signs, in particular:

6. Thigh circumference with abdominal protrusion

7. Neck circumference

8. The shoulder girth

9. Head circumference

[0034] In contrast to the known methods for three-dimensional scanning of a user's figure using special equipment (three-dimensional laser scanners), photographing a figure using a reference object, and photographing a figure against the background of an orthogonal grid, the claimed method proposes the refinement of dimensional signs based on human height and the position of the supporting points of the skeleton, which the user can clarify using the photograph (Fig. 4-5).

It is possible to clarify the characteristics of one photograph (front), two photographs (front and back) and three photographs (front, side, back). The only requirement for photography is to position the camera at such a distance from the floor and from the object so that the distortion of perspective is minimal, a distance of two growths, at a height of half the height, is recommended. Depending on the number of photos, the characteristics are refined by comparing a different set of attributes, however, sufficient accuracy is achieved in all cases thanks to an extensive database of typical figures.

[0035] After constructing a 3D dummy and clarifying dimensional characteristics, the system allows you to record them in your personal account for subsequent use (design and fitting).

It is also possible to export a file for printing a dummy on a 3D printer in real size.

[0036] The construction of the dummy takes place in three stages:

1) development of a preliminary design, on which a preliminary estimate of the shape of the mannequin is performed on the outline of the figures in two projections: transverse vertical and longitudinal vertical, the main projection measurements and the diameters of the mannequins are aligned, as well as the contour lines of the mannequin are developed;

2) the construction of drawings of mannequin sections, approximation of the contours of sections by regular curves and setting these curves using graphical and computational methods. In the stage of technical design, the development of mannequin sections is carried out on the basis of the averaged contours of the figures of a typical physique taking into account posture;

3) restoration of the surface as a whole.

[0037] At step 105, refinement of dimensional features based on the constructed three-dimensional dummy is performed.

First, the horizontal planes of heights are determined vertically, based on dimensional features (Fig. 6). Next, vertical planes are determined that divide the horizontal planes in accordance with the frontal projections of the figure, laying aside half of the dimensional sign in both directions (verticals xn and chl) from the axial vertical, using transverse diameters.

When constructing a mannequin and recalculating dimensional signs on its basis, the system recognizes dimensional signs that can vary depending on the position of soft tissues, for example, the height of the nipple point or the height of the waist line (Fig. 7). The remaining points are skeletal; they are defined as constants for the dummy.

Next, the position of the mannequin reference points is determined by the anteroposterior diameters, the vertical is 0 ° in front, 0 ° in the rear.

[0038] At step 106, an analysis of the features of the figure under which the garment is created is performed. In particular, a determination is made of the type of posture of the figure, kinkiness, tilt of the shoulders, the location of fatty tissues, the degree of development of the muscles of the supporting belt, etc.).

These individual parameters are taken into account using the created three-dimensional dummy.

[0040] At step 107, the construction of the product pattern algorithm is performed based on the dimensional features entered at step 102. This stage is performed with the participation of the user and the software and hardware platform that implements the main functions of the claimed method.

[0041] For the description and construction of patterns of models of garments in the system, a simple specialized language is used to record the methods for describing and constructing patterns (the programming language of sewing patterns), which allows you to record geometric constructions using a set of operators, qualifiers (properties of objects), control structures (conditional operators and cyclic constructions).

Unlike existing CAD systems, visual tools for working with graphic objects are absent or limited to obtaining the name and properties of the object. For example, when you double-click on an object, the name of the object will be substituted into the code window. When you click on the "line" button, a tooltip will be added to the code window

line (point, point);

By analogy with programming languages, we will call the rules for writing descriptions of building models of garments the syntax and semantics of the language, individual elementary actions - operators, and the textual description of the algorithm as an analogue of the program.

[0042] Several different interpreters of the pattern algorithm allow:

- Instantly display the pattern on the screen;

- Play the process of displaying the pattern in the form of an animated film as a whole or to the current cursor position in the code window - to search for errors in the construction process (error closing the tuck, transferring the cut at the wrong angle);

- Automatically create a master class in video format or in an e-book format for this sewing technique with comments along the animation and decoding actions, quantities, conditions, cyclic constructions in the form of instructions adopted in sewing textbooks;

- Automatically create a technical drawing of the future garment in monochrome plane format with the display of the main contours, seams, slots, for use in print media when publishing patterns. The technical drawing can be adjusted by means of the system if the designer wants to give him certain design characteristics;

- Automatically prepare the sequence of actions for collecting the garment in the form of sewing instructions, including the recommended fabric consumption, the number of parts and the features of their cutting, the sequence of steps for collecting parts, illustration of complex technical steps (folds, assembly of shuttlecocks), illustration by pairing small copies of parts patterns;

- Create a set of patterns in a given format, broken down into sheets for export and printing;

- Create a 3-D preview of the technical drawing on the dummy or without displaying the dummy (product only).

[0043] If you take any pattern construction technique, then the first action of the constructor is to set a point in some coordinate system. Then, lines, segments, arcs are built, according to the given conditions, straight and curved lines are drawn. Any technique implies a set of fundamental elements: a coordinate system, units of measure, an accessible set of tools and operations, initial data (dimensional features, design task, sketch).

The basis of the system is the calculation of the coordinates of the control points of the pattern using arithmetic formulas in which you can use the values of dimensional attributes from the database (step 1071). You can also use in formulas: numbers given by constants; formulas calculated variables; lengths, distances, angles, defined between different elements. When writing a pattern construction technique, you can use:

- points can be specified by coordinates; plotted from another point to a length at an angle; defined as the intersection of curves, segments, broken lines; defined by the deposition of length along a segment, arc, curve, broken line;

- segments defined by two points;

- arcs;

- curved lines defined by the start point, end point, tangent angle at the first point, tangent angle at the second point, convexity coefficient;

- broken lines that can combine segments, arcs, curves in series.

[0044] All geometric objects (values, points, segments, lines) in the system have their identifier (name) that uniquely identifies this object. An identifier (name) is a sequence of letters, numbers and the symbol “_” starting with a letter. Letters not only of the English alphabet can be used (Cyrillic, etc.) within the framework of the utf-8 encoding, uppercase and lowercase letters can be used, between which no distinction is made.

[0045] When recording the formulas for calculating coordinates in a program, dimensions of dimensional attributes selected from a database created using the system can be used. Values of dimensional signs can be used in formulas as variable-numbers and are indicated in accordance with serial numbers (for example: sz23, sz1, sz56, sz114) or with user-designated designations (for example: obkh1, obkh2, waist).

In FIG. Figure 9 shows an example of building a skirt frame using the operators described above:

Iength = sz9-sz7; // skirt length will be determined at the knee level for any height

ea19 = sz19 * 0.05; // increase in breathing along the hip line will be equal to 5 percent of the thigh circumference

width = sz19 * 0.5 + ea19; // half the width of the product is equal to half the circumference of the thigh + increase

P1 = point (0,0); // put the first point

P2 = apply (P1, width, 0); // put the width of half of the product to the right of point P1 and put the point P2

P3 = apply (P1, length, 90); // put down the length of the product down from point P1 and put the point P3

P4 = apply (P2, length, 90); // put down the length of the product down from point P2 and put point P3

centerback = line (P1, P3);

centerfront = line (P2, P4);

hem = line (P3, P4);

[0046] To specify the coordinates of geometric objects in the system, a rectangular coordinate system is defined: the point (0,0) is the origin, the X axis is the horizontal axis directed from left to right (first coordinate), the Y axis is a vertical axis directed from top to bottom (second coordinate). This direction of the axes is chosen due to the fact that the construction, as a rule, is from top to bottom, and the selected direction of the Y axis provides work with positive increments of coordinates. The unit of measurement along the axes is 1 centimeter. The positive direction of the reference angles is traditionally from the X axis to the Y axis, and due to a change in the direction of the Y axis, the positive direction of the change in the angles is clockwise.

[0047] The system allows modeling using the programming language of sewing patterns using operators that sequentially define variables or perform certain actions (for example, printing).

All statements are executed sequentially unless there is an explicit indication of a change in the sequence of statements. When the program is running, the coordinates and parameters of the variables are sequentially determined. Variables are directly defined using the following keywords: point, line, circle, arc, curve, path (i.e., point, line, arc, 2 degree curve, 3 degree curve, broken line).

[0048] It is possible not to directly define the variables, but to construct them using the built-in functions (determining points through the intersection of objects, transfer or rotation of objects). For each type of variable, a set of valid actions is defined: intersection, parallel transfer, central and axial symmetry, rotation, printing. Almost any of these transformations can also be implemented using the formulas for calculating coordinates, but using built-in functions allows you to simplify the recording.

[0049] The system consists of sequentially defining new geometric objects — variables, whose coordinates are calculated using formulas or determined using transformations. When the program is executed, the interpreter sequentially looks at the operators and performs the actions defined by them.

[0050] In general, the operations of the proposed language correspond to the operations performed when constructing the drawings manually. This correspondence and the possibility of multiple quick “re-construction” of the drawing make the system easy to use, and the formalism of construction and the possibility of using a database with stored values make it possible to use the system as a really serious workstation.

[0051] Corner construction

The qualifier of the angle between three points allows you to perform precise operations of turning and copying objects (closing the shoulder tuck and forming a tuck in the armhole, copying objects to create a take-off part at an oblique angle, and so on).

With manual construction of patterns, the designer most often operates with linear values, even in cases of working with tucks, not a tuck angle, but a tuck solution in centimeters is taken to build. However, when transferring darts indicating centimeters, the convexity parameters are distorted at a given point. For example, transferring a tuck solution from the shoulder to the nipple point, equal to 7 cm in the side seam by the same 7 cm, we will get a noticeably more convex surface, since the side seam is closer to the nipple point. When using the system operator, the angle transfer convexity parameters will be completely preserved.

[0052] Comments on the steps of the algorithm are written to lines or parts of lines starting with //, if a comment consists of several lines, it should be limited to the character set / * and * /.

The comment may contain any text explaining the actions performed, giving links to literature, reminders, copyright details, advertising information. When you start the interpreter to generate a master class in video format or instructions for this sewing technique in e-book format, comments will be automatically included in the video sequence and in the text of the e-book by analyzing the lines of the algorithm.

[0053] The basic elements of the language described above make it possible to perform almost any geometric transformation by calculating coordinates, but in some cases the formulas of such a transformation will look too bulky and incomprehensible. To improve and enhance the visibility of the recording of some transformations, simplify writing programs in the system language, built-in functions are introduced. Built-in functions allow you to perform the most common transformations on objects (fragments of part contours).

Some functions:

Axial symmetry, or symmetry relative to the segment

It is convenient to use symmetry when modeling a collar when it is constructed in a “deferred” form and then displayed relative to the fold line. Often when modeling requires a complete symmetrical pattern. You can get a detailed drawing of, for example, a shelf by displaying its outline relative to the middle of the shelf.

Transfer

It is convenient to use when creating a part based on existing objects, which it is desirable to visualize in a separate area of the screen in order to avoid a high density of control points.

move ((shoulder, armhole), transfer_, (shoulder_k, armhole_k));

In this case, the variables “shoulder” and “armhole” (for example, a segment and a curve) will be transferred in the direction of the vector specified by the segment “about transfer”, and their copies will be called “shoulder_k” and “armhole_k”, respectively.

Rotate around a point at a given angle

Rotation can be used in the construction and transfer of darts, when constructing coquette, complex draperies and folds, and so on.

Compression

When constructing patterns for materials (step 1072) with an increased extensibility group (knitted fabrics, especially using lycra), it is necessary to compress individual sections of the pattern to account for their subsequent stretching. In some cases, on the contrary, it is required to stretch the pattern to account for its subsequent compression due to shrinkage of the fabric or the use of any processing technology. For such a modification of the pattern, the system has a compression function in two directions. To set the compression function, the compression center, the angle of the main compression direction, and the compression coefficients along the main direction and along the perpendicular direction are necessary.

Intersection

Almost all pattern construction is based on intersection. This can be the intersection of lines, arcs, segments in any combination of them. Often, intersection is used in modeling - drawing shaped lines and determining their position on the contour of patterns, transferring darts, etc. To implement such actions, the language provides functions for intersecting directions, arcs, broken lines, curves, segments.

Tuck

The “Tuck” operator is designed to translate the tuck and design the ends of the tuck, depending on the processing method.

Fold

The crease operator is designed to create crease depth from a point at a given angle to a given crease depth.

Crop

This operator is intended for drawing contours of a pattern with curly lines, as well as for drawing these lines on a pattern. For example, the bottom of the coquette must be decorated with scallops or a line for attaching a decorative braid.

Dilute

This operator is designed for conical breeding of parts when creating shuttlecocks, draperies, details of collars and cuffs, etc.

[0054] A system that implements method 100 allows a build animation to be performed with which you can check the sequence of creating pivot points, hyphenation, and is also a visual debugging tool. Another use case for the animation interpreter is looping.

With the selected animation option for cyclic constructions, you can trace the entire step-by-step operation of the cycle, determine the initial value of the selected parameter, and find the optimal increment to reduce the number of iterations.

For example, when building a raglan, the angle of inclination of the back and front of the sleeve is selected in the cycle. When debugging a cycle, you can trace how the angle of inclination changes, determine which increment of the angle you need to set in order to find this angle with a given accuracy, and thereby reduce the number of iterations.

[0055] After creating a pattern algorithm based on it, a process of automated calculation of tailoring of a garment occurs, on which:

- Pattern areas marked as to be strengthened by adhesive pad are highlighted.

- The details created by the methods of "folding", "assembly", "shrinkage" are highlighted.

- The pattern algorithm is analyzed to determine graphic objects created using the symmetry, transfer, equal length deposition, separation of polygons into two patterns. At this stage, the program pattern code is analyzed to highlight pairs (triples, etc.) of objects that may have equal characteristics.

- The resulting pairs of sections on the two-dimensional polygons of the patterns are further analyzed for the coincidence of reference points and seam lengths. These can be lines, curves, broken lines, as well as sections of similar graphical objects between set marks.

- The necessary sequence for grinding parts is determined, including combining several individual patterns of the front into one before attaching to the rear panel, closing the tucks before attaching to the belt, etc. The principle of selecting a sequence is to simplify sewing operations as much as possible, to make seams so that the parts do not have to be connected at an uncomfortable angle, attach two parts to the third if there is one common seam (two parts will be combined first, then the seam will be made with the third); straightening the seams if possible, control of the possibility of turning the part after sewing on the lining, and so on.

- The system user is given the opportunity to change the order of operations if there are variations of preliminary grinding of parts before critical operations (for example, you can first close the yoke of the yoke, then grind it to the lower panel or sew the yoke and lower panel, then close the yoke of the yoke). The system monitors the sequence of operations and returns an error if the user, for example, wants to sharpen the belt before closing the tuck on the skirt.

- The sequence of actions in the form of a sewing algorithm is written to a file, or a record is made in the database, for example: glue (front_stitch, back_stitch);

fold (coquette);

stitch (a_p3_p4 (front), a_p3_p4 (back);

bend (l_p1_p4 (before);

[0056] The steps for processing the button placket, stitching the zipper, processing the slots, and some steps for attaching the lining are automatically added. The sequence of actions is recorded automatically using the functionality implemented by the system, and is also saved in the background during the editing process by the user in case of, for example, network failure, disconnection, etc.

Based on the sewing algorithm on the patterns of patterns for 2D printing, the interpreter additionally marks the order of operations, for example, the same texts are added along the side seams in the front left and the back to the right, for example, “seam 21” along the edges to be sewn, marks are placed at the beginning and end of the seam, e.g. (w21 >>) and (<< w21).

This increases the visibility of the resulting patterns and facilitates the process of stitching parts.

Based on the patterning algorithm and the sewing algorithm using the lexical interpreter of the instruction, an instruction for sewing is automatically created in the language selected by the user and provided with illustrations. The language can subsequently be changed and the system will automatically translate.

When creating instructions for tailoring the product, you can optionally include or not include illustrations of the collection of parts.

Parts of the instructions may include:

- 3D image of the finished product

- Technical drawing of the product in accordance with the standards of the clothing industry

- Recommended fabric (elongation, shrinkage characteristics)

- Parts List

- Recommended amount of fabric per specific size

- The sequence of collection of the product.

[0057] The characteristics of the recommended fabric and additional materials are established as a result of the analysis of the algorithm by the system, including

- the presence of the operator "shrinkage" with negative coefficients,

- type of size / age group (clothes for children),

- a numerical and percentage assessment of the increase in free fit, numerical characteristics and the presence of cuts in anthropometric sections (neck and collar widths, the presence of a zipper or buttons or cuts in this section, the total length of the bottom of the skirt, the presence of cuts or slots, and so on) .

According to the obtained characteristics of tissue extensibility, a reconciliation with the base of tissue types takes place and a selection of the corresponding positions is made. An indication of the type of fiber can be given (for example, in the case of clothes for toddlers and primary school children, the recommendation is to use natural fabrics.)

The pattern algorithm is analyzed by the system for the content of buttons, zippers, hooks, reinforcement with corset stones, etc. Such information is also included in the text of the instructions. If there is no indication of the method for processing the slices by bending, the length of the oblique collar is calculated by the algorithm. The length of lightnings and similar elements is automatically calculated and indicated. As a result, the text in any of the selected system languages is written into the instructions, for example, Recommended fabric:

Knitwear, jersey, dress fabrics with elastane, stretch gabardine, etc. tensile strength of at least 5% of artificial, mixed or natural fibers.

You will also need:

Glue pad, lining fabric, zipper (minimum 25.6 cm), 1 button. Optionally:

Slanting inlay 1.5 cm wide and 37.5 cm long for processing the "seam21" section between the marks (w21 >>) and

(<< w21) on the "Before" part.

Metric units depend on the settings of the customer of the pattern, that is, if the order prefers "inches" when ordering the kit, in the example above there will be lightning 10.1 inches long, etc.

[0058] The list of parts is included based on an analysis of the pattern algorithm, indicating the number of parts, the need to mirror them, and fabric types. Next to the parts list is a thumbnail image of the economical layout of parts on standard-width fabrics, parts on the layout plan are marked with letters, letters are also indicated in brackets next to the name of the part in the list. In FIG. 10-11 shows an example of displaying a list of parts based on the created pattern algorithm.

[0059] The recommended amount of fabric is automatically generated and performed by maximizing the compaction of curved polygons in a few iterations. Specific lengths are calculated, for example, the main fabric is 45 inches wide and 2 yards long and so on. Metric units depend on the choice of the customer patterns and can be changed at any time.

[0060] A product collection sequence is created using a lexical interpretation of the sewing algorithm and using a database of sewing terms in several languages. All actions are accompanied by illustrations, illustrations can be turned off if desired.

In FIG. 12 shows an example of generating a product collection sequence. Each line of the sewing algorithm is analyzed by the lexical interpreter; in addition, an appeal can be made to the pattern algorithm if it is necessary to refine the seam allowances and so on.

The designer can supplement the instructions, but cannot edit the sequence and what is shown in bold text, since this information is needed to display illustrations and is calculated in accordance with the algorithm.

[0061] At step 108, the reference points and patterns of the garment are recalculated to identify intersections of the elements of the garment and the matching lengths of the combined seams and parts of the garment.

This stage is implemented using special formulas in which, in addition to constants and variables - dimensional features, you can use the parameters of other geometric objects, including the coordinates of points, the corners of the segments, the angles of the tangent curves, the lengths of the segments, curves, arcs, broken lines.

This allows you to achieve:

- The exact conjugation of the corners in different sections of the garment (for example, the armhole of the shirt at the bottom point is formed by two curves to which the side seam of the product fits at some angle. When using the corner conjugation function after sewing the side seam, the section formed by the two armhole curves will be flat, and the side seam will fit it perpendicularly);

- Exact correspondence of the length of curved seams, shuttlecocks, sleeve heads relative to a given section of the armhole;

- Automatic marking at the desired length from the beginning of multidirectional cut curves;

- Automatic affixing of control points on the patterns (for example, using the lengths of the curves of the top of the product to mark points on the straight belt);

- Product robustness checks in different sizes.

The system also allows you to perform construction animation using the animation interpreter, which allows you to check the sequence of creating points, rotation, transfer, and is a visual debugging tool. Another use case for the animation interpreter is loop processing.

With the selected animation option for cyclic constructions, you can trace the entire step-by-step operation of the cycle, determine the initial value of the selected parameter, and find the optimal increment to reduce the number of iterations. For example, when building a raglan, the angle of inclination of the back and front of the sleeve is selected in the cycle. When debugging a cycle, you can trace how the angle of inclination changes, determine which increment of the angle you need to set in order to find this angle with a given accuracy, and thereby reduce the number of iterations.

[0062] In step 109, the fit of the garment on the created three-dimensional mannequin is checked. In the general case, the garment is collected at the described seams and recorded in a file as a three-dimensional surface with holes. The three-dimensional surface of the garment, taking into account the extensibility of the fabric and gravity, is put on the mannequin, taking into account the supporting belts: 1) shoulders 2) spinous-ilium. It is checked whether there is no intersection of the surface of the garment with the surface of the mannequin (the garment is too tight, it intersects inwardly around the girths, the circumference of the slots of the garment is insufficient for free passage of the neck, arms, legs, and waist); it is checked whether the slot is small enough to cause gravity the item did not fall from the support belt (shoulder or pelvic girdle depending on the item of clothing), if any size falls out of the general range of sizes.

[0063] At step 110, a check is made to build patterns for a wide range of sizes. This check is carried out using the gradation procedure. Gradation can also be checked on the grid of patterns, and the propagation of patterns does not occur by increasing the part as a whole, but by recalculating the algorithm to new dimensional characteristics from the database. This allows you to determine whether any size falls out of the general range of sizes, if there are any errors in the construction, whether the configuration of the designed garment corresponds to all sizes. An analysis is made of the possibility of constructing a garment for a specific standard dimension adopted in the industry or specified by the user, for example, a garment can be made in sizes from 34 to 48, but can no longer be made in 50 due to the features of the algorithm.

When constructing a grid of patterns, the system displays the numerical values of variable graded sizes. The entire text can be printed out and then analyzed how various values change during gradation and, if necessary, make appropriate corrections to the algorithm.

[0064] At step 111, the patterns are exported to a machine-readable format selected by the user. A set of patterns can also be exported in a given format with the division into sheets for export and printing.

The user can transfer the resulting patterns through a data network to another user or send them to a remote server in the module of the trading platform.

[0065] A system that implements method 100 also allows the creation of a masterclass using the sewing technique used to design the garment. The designer proceeds to create the masterclass after creating the pattern algorithm. To start recording, the designer activates the "masterclass" function in the pattern editor window.

First, a frame for the name of the master class is created according to one of the proposed templates, which the designer can choose in his office, indicating the background picture, fields, preferred font, font size and font color of headers and other styles, comments field color, author data.

Next, the pattern algorithm is analyzed and the dimensional features used in the construction process are determined (a list of szXX constants in the algorithm text is compiled). The splash screen "Necessary dimensional signs" is formed.

Mini-rollers are sequentially recorded in the video, which are formed on the basis of a database that describes the process of removing these dimensional signs. The videos contain a schematic image of the figure of the corresponding dimensional group, the name of the dimensional sign, a full description of the dimensional sign, additional tools necessary for taking measurements, their location on the figure, animation of the dimensional sign on the figure.

[0066] The lines of the pattern creation algorithm are sequentially analyzed. When calculating the increase in freedom of fit eaXX and additional variables between the algorithm operators either inside the algorithm functions, the explanation of the calculations is displayed in the animation frame or in separate frames in the case when the length of the resulting text exceeds 500 characters.

The operators used in the construction process are described in terms familiar to a designer with experience building on paper. The lexical interpreter creates the text according to the rules described in the system and displays it under the animation construction window in the comment field. Constructor comments in the algorithm text are displayed immediately before the animation of a particular operator. The animation duration of a particular construction is calculated depending on the length of the text in characters.

Algorithm Example:

p1 = point (2,2);

ea18 = 1;

p2 = apply (p1, sz26 * 0.5.90);

// The side seam is located in the middle between the waist at the back and the waist at the front.

p3 = apply (p1, sz18 * 0.25 + ea18.5);

back_ belt = curve (p1, p3,0,10,1);

middle_shoe_backs = line (p1, p2);

ea20 = 2;

p4 = apply (p2, sz20 * 0.5 + ea20,0);

bottom of the product = line (p4, p2);

p5 = apply (p4, sz25 * 0.3.90);

side_show = line (p4, p5);

lightning = curve (p3, p5.50.90.90);

marker = (p5,4,180,1,2);

sa0 = 1cm,

sah = 2cm,

back = pattern (name = "Back panel", sym = 0, fold = (middle_back_shirt),

contour = (back_band, zipper, side_shirt, bottom of the product, middle back seam),

seam = sa0,

seam_special = (bottom of the product = sah), grain = (middle_shirts_backs));

Mentioned masterclass on tailoring products can also be issued in the form of an electronic book, which may also contain relevant illustrations and animations. The format of the book can be: PDF, EPUB, MOBI, FB2, DOC and others.
