Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grading device used for grading patterns on clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of device has been used, for example, in the field of clothes. Grading is the process of enlarging or reducing one pattern to create a pattern of another size in order to meet the diversification of clothing sizes. Conventionally, in this grading, since the designs of clothes to be handled are various, various editing operations are performed on the pattern, and the pattern thus modified is subjected to a grading pitch (hereinafter referred to as a variation amount between the sizes). The procedure is simply specified.

For the designation of the grading, a method is often adopted in which a reference direction is set for each pattern and the pitch is designated by this direction and a direction orthogonal thereto, that is, a moving pitch in the X and Y directions. . In the case of such a pitch designating method, when an editing operation such as rotating a block is performed, the pitch with respect to the reference pattern changes, so that the procedure of designating the pitch after the editing operation is inevitably unavoidable.

[0004]

However, this is very troublesome because the grading pitch has to be specified again each time a new design is made. And
As an editing operation for the pattern, for example, FIG.
As shown in (1, 2), the yoke portion is cut from the body along the line AB, and as shown in FIG. 8 (1, 2), the body part of the constituent points ABCDEFGHI is , Move part of the darts AOI to the darts COD to erase the darts and make it a gather.
An operation such as further rotating by an angle θ from the darts is often performed around. After such an operation is performed, in order to obtain a pattern of another size by grading, the movement pitch of the position in the middle of the line segment is calculated, or the movement pitch is calculated by rotating a part of the pattern, etc. Then you have to specify the pitch. It was very difficult to perform the pitch designation as described above after the editing operation was performed many times.

The present invention has been made in order to solve the above-mentioned problems, and when a pattern is partially edited, the pitch can be calculated and reset so that the grading can be performed quickly. It is an object of the present invention to provide a grading device capable of obtaining a result.

[0006]

In order to achieve this object, the grading apparatus of the present invention is a pattern editing apparatus for editing a pattern by cutting a part of the pattern or displacing the part. In a grading apparatus, which is provided with means for grading a part of the pattern edited by the pattern editing means, the coordinate positions of the constituent points constituting the part of the pattern edited by the pattern editing means are set for each size. And coordinate pitch conversion means for converting the coordinate position of each constituent point of each size calculated by the coordinate calculation means into a grading pitch.

[0007]

According to the grading apparatus of the present invention having the above structure, the pattern editing means forms a part of the edited pattern by cutting a part of the pattern or displacing the part. The coordinate position of each constituent point is calculated for each size by the coordinate calculation means, and the calculated coordinate position of each constituent point for each size is converted into a pitch by the coordinate pitch conversion means.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a grading apparatus of the present invention,
It is a block diagram which shows the structure of the Example embodied on the workstation as an apparel CAD system.

To the main body 1 of the workstation, a mouse 6, a keyboard 7, a digitizer 8, a hard disk 9 as a storage device, a display 10 and a plotter 11 as output devices are connected. Also,
The workstation body 1 is mainly composed of a CPU 2 and a ROM.
3, RAM 4 and interface 5. The workstation body 1 controls the entire apparel CAD system including grading processing.

The ROM 3 stores a program for controlling the apparel CAD system, for example, a program for grading. RAM4
Is provided with an area and the like for storing calculated values required for each edition. The interface 5 is
It is for relaying input / output of information and the like with various peripheral devices.

The mouse 6 and the keyboard 7 are
This is for performing operations such as instructing the CPU 2 for pattern editing work. The digitizer 8 is for inputting a pattern displayed on a paper pattern. The hard disk 9 stores data such as part shape and pitch. The display 10 displays the pattern of the pattern based on the data, and the plotter 11 prints the pattern of the pattern.

The shape of the pattern is the pattern table 91.
Are indicated by the coordinates of each point (called a constituent point) that determines the shape of this pattern. Further, the pitch is indicated in the pitch table 92 by the arrangement number of the designated point and the movement amount in the movement direction for each size. The movement direction holds the X direction for each part, and the pitch is indicated by the movement amount in the X direction and the Y direction orthogonal to the X direction.

The present embodiment is constructed as described above.

The process of the pattern cutting operation will be described below with reference to FIGS. 2 and 4. FIG. 4 on the display 10.
When the pattern as shown in (1) is displayed, the case where the straight cutting lines are designated at the positions intersecting at the central positions EF of DA and BC is taken as an example.

The positions (E and F in the figure) where the line segment of the master size and the cutting line intersect are calculated and set in the cutting point coordinate area 41 (S101, S indicate steps. The same applies hereinafter), and the master size is set. Data of the cutting pattern is created (S102). Next, the positions of the cutting points E and F after grading are calculated and set in the editing point grading coordinate area 45. In this case, the cutting position EF is DA
And BC are positions to divide each into two. Cutting position EF
The positions E'F 'and E "F" of the other sizes are line segments (D'A and D "A, B'C' and B" of the respective other sizes.
C ") is calculated as a position that divides it into two (S10).
3). Then, the grading pitch is calculated from the position after grading. The pitch may be obtained from the XY coordinate difference between E, E ′, and E ″ and the XY coordinate difference between F, F ′, and F ″ (S104). Finally, the points E and F generated at the cutting positions of the two cutting patterns are set to the pitch obtained in S104 (S105), and the thus obtained patterns after cutting are shown in FIG. 4 (2). The display 1
It is displayed at 0 (S106).

Next, the process of rotating the block will be described with reference to FIGS. 3, 5 and 6. Display 1
When the pattern of FIG. 5A is displayed at 0, the block surrounded by the constituent points CDEH of this pattern is
A case will be considered in which the configuration point C rotates about the configuration point C until the configuration point D hits the configuration point B so that the state shown in (2) is achieved.

First, for the master size, the angle θ for rotating the block CDEH is calculated. In this case, the angle θ of the rotation angle BCD may be calculated (S111). Then, data after rotation of the master size is created (S
112). Next, the pitch of each constituent point included in the rotated block is calculated. Since it rotated around the configuration point C,
As shown in FIG. 6A, one pattern with reference to the configuration point C is generated for only the rotated portion and set in the rotation block pattern area 43. And
For each of the constituent points included in this, the pitch in the non-rotated state is calculated and set in the rotation block pitch area 44 (S113).

Next, for each size, the angles θ'and θ "for rotating the blocks C'D'E'H 'and C" D "E" H "are calculated. In the state of FIG. Corner B'C '
The angles θ'and θ "of D'and the angle B" C "D" may be calculated (S114). Using this, the coordinates D'E 'of the rotation block CDEH in the rotated state as shown in FIG. 6B.
H'and D "E" H "are calculated and set in the edit point grading coordinate area 45 (S115), and the corresponding points (D and D'and D", E and E'and E ", H and The pitch is calculated from the difference between the XY coordinates of H'and H ") (S116). Finally, a pitch obtained by adding the pitch of the rotation center point C and the pitch calculated in S116 to the points D, E, and H of the pattern after rotation is set (S117), and after the rotation obtained in this way, 5 (2), which is the pattern of the above, is displayed on the display 10 (S118).

The pattern cutting process shown in S101 to S102 and the block rotation process shown in S111 to S112 are examples of the function as the pattern editing means of the present invention. Further, S103 and S113 to S11
Each of 5 functions as the coordinate calculating means of the present invention.
