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 a pattern of clothes or the like, and more particularly to a grading device which is designated by a pitch system.

[0002]

2. Description of the Related Art In order to meet the diversification of clothing sizes,
Grading is the process of enlarging or reducing one pattern to create a pattern of another size. Conventionally, this grading is often specified by the pitch method. This is a method that specifies the amount of change required to change a point that determines the shape of the pattern to a point on a pattern of a different size, in two orthogonal directions. is there. At this time, the pitch is almost always changed by inputting a value in a table format. As shown in FIG. 6, as the input pitch, two methods are conceivable: when the displacement from the master size is designated (1) and when the displacement from the adjacent size is designated (2).

Consider the operation of changing the pitch of a certain size when the grading for expanding to several sizes is specified. This results in changing the shape of the pattern of that size. When the shape of the pattern of the size in the middle is changed, it is necessary to change the shape of the pattern of the size after that (a), and the shape of the pattern of the size after that is left as it is. When it is good, the lid street of (b) is considered. This is shown in FIG. When only the necessary values are changed in the table, if the pitch is specified in (1), the result of b is obtained as shown in FIG. Further, if the pitch is designated in (2), the result of a is obtained as shown in FIG.

[0004]

In the conventional grading apparatus, when only necessary values in the table are changed, only one of the above two cases can be obtained.
If a different result was desired, the user had to modify the value for the pitch of the size affected by the shape change.

The present invention has been made in order to solve the above-mentioned problems, and when the shape of a pattern of a size in the middle is changed, the shape of a pattern of a size after that is changed in the same manner. It is an object of the present invention to provide a grading apparatus that can easily obtain two kinds of grading results, that is, that the shape of a pattern having a size after that is left as it is.

[0006]

In order to achieve this object, a grading apparatus of the present invention is a grading apparatus which specifies a grading by a pitch method, and a single size edit mode for editing a pitch of a certain size and a certain size. And a pitch edit mode selecting means for selecting a continuous size editing mode for editing a pitch of a size continuous with the pitch, and a pitch determination when the mode selected by the pitch editing mode selecting means is the continuous size editing mode. A first pitch determining means for performing processing, and a second pitch determining means for performing pitch determining processing when the mode selected by the pitch editing mode selecting means is the single size editing mode. ing.

The pitch of the sizes may be set according to the amount of change between adjacent sizes.

[0008]

According to the grading apparatus of the present invention having the above structure, when the mode selected by the pitch edit mode selecting means is the continuous size edit mode, the pitch determining processing is performed by the first pitch determining means. In this case, the pitch confirmation processing is performed so that each of the successive sizes after the pitch-edited size will be affected by the editing result. When the selected mode is the single size edit mode, the pitch determining process is performed by the second pitch determining means. In this case, the pitch confirmation processing is performed so that the shape having only the size subjected to the pitch editing is affected by the editing result.

Embodiments of the present invention will be described 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.

In addition to the main body 1, the workstation is
Mouse 6, keyboard 7, digitizer 8 as input device, hard disk 9 as display device, display 1
0, the plotter 11 is connected. The workstation body 1 is mainly composed of a CPU 2, a ROM 3, and a RAM.
4 and interface 5. This controls the entire apparel CAD system including the grading process.

The ROM 3 stores a program for controlling the apparel CAD system, for example, a program for grading. In RAM4,
Table 41 of the pitch for which the grading pitch is specified,
Storage areas such as the edit mode flag 42 and the input buffer 43 are provided. The interface 5 is a connecting means for communicating with various peripheral devices.

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

The shape of the pattern is indicated by the coordinates of points (called constituent points) that determine the shape of the pattern. The grading adopts a method of designating the coordinates of these constituent points by the amount of change in two directions, the X direction and the Y direction, which are unique to the system. In addition, the amount of change from the adjacent size is input as the pitch.

A mode is provided for pitch designation in a table format,
It is possible to select whether to change only the edited size (single size editing) or all subsequent successive sizes (continuous size editing).

Next, the operation of the grading apparatus constructed as above will be described.

The pitch fixing operation when the pitch is edited with respect to a certain point of a certain size will be described with reference to the flowchart of FIG. First, it is checked whether the edit mode flag is the continuous size edit mode or the single size edit mode (S10).
1 and S indicate steps. The same applies below). If the continuous size edit mode is selected, the shape of each subsequent continuous size similarly changes according to the value of the edited size. Therefore, the value of the input buffer is fixed as it is (S
104). On the other hand, in the single-size edit mode, it is necessary to limit the transformation to only the edited size. Obtain the amount of change from the new value for the pitch being edited (S102),
The amount subtracted from the pitch of the adjacent size is reset by this amount (S103). Then, the value of the input buffer is determined (S104). FIG. 5 shows an example during editing.

The processing step S101 functions as a pitch edit mode selecting means. Also, the processing step S
104 functions as a first pitch determining means. Further, the processing steps S102 and S103 function as a second pitch determining means.

In the present embodiment, the reference size of the input pitch is set to the adjacent size. However, the case of inputting the displacement from the master size and the case of inputting the displacement from the adjacent size are switched during editing, and according to it. It is also easy to perform a confirmation operation.

[0020]

As is apparent from the above description, according to the grading apparatus of the present invention, when the pitch of the size in the middle is corrected and the shape of the pattern of the size is changed, the subsequent consecutive It is possible to easily obtain two kinds of grading results, that is, changing the shape of the pattern of each size to be changed in the same manner and leaving the shape of the pattern of the subsequent size as it is.
