Description

Clothing pattern drafting method {Method and medium for organic apparel pattern}

The present invention relates to a method of drafting a clothing pattern, and more particularly, when inputting a garment in a computer CAD (CAD), the input process of the pattern design is represented by a segmented line division type to form a pattern. The present invention relates to a method of drafting clothing patterns in which points and line elements are linked to each other and the body dimensions are linked to the pattern elements so that the size is automatically adjusted according to the body size of the customer.

In general, modifying one part of the garment actually results in some deformation in all parts of the garment, since one pattern is sewing and connecting with another pattern to complete the garment. Of course, it requires a high level of skill because it can harm the overall aesthetics of clothing.

Therefore, in the present invention, by modifying the clothing pattern by writing a specific software program, the drafting method is formalized, and given the correction part and the amount, each part of the related pattern is automatically corrected as a program input value.

For example, in the conventional art, when designing a garment copy, a contour extraction dead copy method is used in which a garment copy is applied to an input device, and an outline and an inflection point are input to record the garment copy. Since it only remembers the coordinate values of the points, it has been a factor that hinders automation because manual work must be done manually to correct errors or adjust numerical values.

Therefore, the present invention is to solve the above-mentioned problems of the prior art, the user expresses the components of the clothing as a program through a command, instead of drafting the clothing pattern directly through the input tool, the components are organically series, Furthermore, the clothing pattern system is provided by providing a program method in which the body size is divided into each element and a second dimension generating algorithm that applies the body size when the body value is input and replaces it with the actual size. Its purpose is to enable computer programming.

In order to achieve the above object, the present invention provides a garment pattern drawing method using a clothing CAD,

Drafting a baseline giving symbols to points and lines,

Drafting a complete line that satisfies the feature lines of the completed line and the construction lines and points of the pattern based on the base line;

It is characterized in that the step of drawing a curved line forming the curve by measuring the length and angle of each part curve.

In addition, the present invention is to program a single garment as a logical construct by the whole of the clothing component pattern elements formed by dots and lines to be mathematically related, and the garment converted into the program is the size measured from the body It is characterized by dividing the clothing pattern into individual parts so that the clothing constituent pattern elements are formulated into a split type, and the mutual elements can be continuously drawn in a line sequence formula.

In addition, the present invention inputs and normalizes the optimal path of the curve and the vibration line through a conventional digitizer device, so that the sewing path is always maintained at the same ratio no matter what size neck and vibration line is given. By applying a curvature proportional algorithm that tracks the optimal sewing path of the complete line of the clothing pattern, the optimum path is reproduced by applying a path in which several patterns are sewn as a ratio value.

In addition, the present invention is the step of selecting a variable dimension from the measurement items, applying the pants dimensions using the variable dimension division formula,

Determining whether the drafting condition is satisfied by comparing the dimensional reference table after the step of applying the pants dimension;

Outputting and storing the sign pattern using an automatic pattern analysis program when the drafting conditions are satisfied;

If the drafting condition is not satisfied, return to the dimension reference table and the automatic pattern analysis program.

Determining whether the simulation is compared with the reference pattern after outputting and storing the symbol pattern;

If it is not compared to the simulation state, the step is terminated, and if it is not compared to the step of selecting a variable dimension among the measurement items, it characterized in that the pants size deformation system using the line segment division method of the clothing pattern component. .

Hereinafter, with reference to the drawings of the accompanying embodiment will be described in more detail the function of the development of the algorithm for the clothing design, the individual clothing program development and the automatic drawing of the clothing program for each customer size, which is a feature of the present invention.

1 is a flow chart showing an example of a symbol pattern drawing method according to the present invention, which includes drawing a base line giving a symbol to a point and a line, and a feature line and a component line of a completed line and a pattern on the basis of the base line. Drawing a complete line that satisfies the above, and drawing a curved line by measuring the length and angle of each part curve.

2A is a diagram illustrating an example of a baseline drawing step in which sequential symbols are given to points and lines.

An example of a program instruction using a typical digitizer device is

VLINE [10,10], 40: Draw vertical line in the direction of the sign from the starting point, ie 40cm (D1 point) in the vertical line from the point [10,10].

ADDP L0.D1, 21.5: Add a point on the specified line segment to effect the split. That is, add point (AddPoint) is displayed on the L0 line segment, and a new sign point D2 is added on the length that is 21.5 cm away from the sign point of D1.

HLINE D1,18: Horizontal division system in the direction of the sign from the symbol point D1 generated after the program execution, that is, the horizontal line (Horizontal Line) 18cm in the + direction from D1, resulting in the symbol point and L1 segment of D3 do

Figure 2b is an illustration showing the drafting step of the back neck line, which is the characteristic point of the completion line based on the base line as an example.

An example of a program instruction for this is

COPY D1, (6.5, 2.3): Copies the point D1 to the point separated by the relative distance deviation given in parentheses. As a result, a point D7 appears. D1 and D7 points become the back and neck points on the pattern.

CURVE D1, D7: As a result, a line connecting D1 and D7 is drawn, but it appears as a straight line, so the control line must be adjusted to show the curvature suitable for the neckline.

FIG. 2C is an enlarged view of D1 and D7 of FIG. 2B, and it can be seen that there are curvature control lines D10 and D11. To move it as shown, execute the following command:

MOVE D11, (0.6888, -1.9505) | D10, (0.3419, -0.9682)

In this case, the control line shift deviations, 0.6888, -1.9505, 0.3419, and -0.9682, are X and Y coordinate deviations, respectively, and select the curve appropriate for the curvature of the wooden line, and adopt the control line value corresponding to the curve. The deviation value of the control line satisfies the case where the relative deviation between the neck and the neck is (6.5, 2.3).

Figure 2d is a diagram showing the drafting step of the shoulder line connecting the neck point and the shoulder point by obtaining the point D8 of the shoulder line and calculating the point D9 of the shoulder point by applying a triangular ratio. The drawing shows an example of the complete line drafting step that satisfies lines and points.

An example of a program instruction for this is

VAL D1.X | MEAS ADD TF1X: Defines X coordinate of D1 point after the neck as variable TF1X and records it in the measurement table which is a memory directory name for later calculation.

VAL D1.Y | MEAS ADD TF1Y: Defines the Y coordinate of the neck end point as the variable TF1Y and records it in the measure table.

VAL D7.X | MEAS ADD TF2X: Define the X coordinate of D7 point, the neck point, as variable TF2X and record it in the measure table.

VAL D7.Y | MEAS ADD TF2Y: Defines the Y-coordinate of the point D7 of the neck as the variable TF2Y and records it in the measure table.

VAL D8.X | MEAS ADD TF3X: Define the X coordinate of D8, the point normally passing through the baseline L4, as the variable TF3X and record it in the measure table.

VAL D8.Y | MEAS ADD TF3Y: The Y coordinate of D8, which is the point normally passed through the baseline L4, is defined as the variable TF3Y and recorded in the measure table.

VAL ((TF2Y- TF3Y) / (TF3X TF2X)) | MEAS ADD TRATIO: In order to find the slope of D8, the point normally passed through the neck and the baseline L4, the ratio of the difference between the X coordinate and the Y coordinate of the two points is defined as a variable TRATIO and recorded in the measure table. .

VAL (TF2X TF1X) | MEAS ADD TLEN1: Define the difference of X coordinate, the distance between the neck point and the back point of the neck, as variable TLEN1 and record it in the measure table.

VAL ((SW / 2) -TLEN1) | MEAS ADD TLEN2: Define the variable TLEN2 as half the width of the shoulder minus the distance between the back of the neck and the side of the neck and record it in the measure table.

VAL (TLEN2 * TRATIO) | MEAS ADD TLEN3: Calculates the product of TLEN2 and TRATIO to determine the position on the Y-coordinate of the shoulder end point of the neck lateral point as a reference point using TRATIO, the slope of D8, which is the point commonly passed through the neck lateral point and the baseline L4. Define it as TLEN3 and record it in the measure table.

Accordingly, the position of the shoulder end point with respect to the neck side point is TLEN2 in the X coordinate and TLEN3 in the Y coordinate. The resulting shoulders connecting D7 and D9 are as follows:

LINE D7, D9 As described above, the present invention proposes a symbolic pattern construction method by sequentially assigning unique symbols to the points, lines, and faces constituting the pattern (cut fabric constituting clothes), and based on the symbols It suggests a program pattern drafting system that works in conjunction. Therefore, since the length and angle are measured for each part and section of the pattern, the error between the input value and the actual garment can be obtained in the program, and the numerical value of the garment can be adjusted according to the body size.

3A to 3C are diagrams illustrating an exemplary embodiment of a road-circle size deformation system using a triangular ratio applied shoulder point segmentation algorithm in the present invention.

The elements of the clothing composition pattern are formed of dots and lines, so that all of these components must be mathematically related to each other so that one garment can be programmed as a logical construct. In this way, the garment converted into the program can be reflected by dividing the size measured from the body to individual portions of the clothing pattern.

It is also possible to handle certain components to adjust only certain portions of the hundreds of components.

To this end, in the present invention, the components may be formulated into a partitioning equation, and the mutual elements may be continuously drawn in a line sequence formula.

In other words, by using a segmentation algorithm that transforms clothing into data and correlates the data to enable logical continuous expression, the clothing pattern drawing method is represented as a computer sequential program.
