DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied as an apparel CAD system for producing clothing patterns will be described below with reference to the drawings.

As shown in FIG. 2, a central processing unit (CP)
U) 1 is connected to a RAM 2 and a ROM 3 as storage devices, a digitizer 4 and a mouse 5 as input devices, and a display 6 and a plotter 7 as display devices.

The CPU 1, the RAM 2, and the ROM 3 perform processing for calculating the angle of the finished line,
The entire D system is configured to be controlled. The RAM 2 is provided with a storage area for temporarily storing data during the process of creating a pattern. The ROM 3 has a storage area in which the programs of the flowcharts shown in FIGS. 3 and 4 are stored.

The digitizer 4 is configured to input the shape of a finished line written on a pattern to the CPU 1. The CPU 1 is configured to set a data point sequence representing a shape formed by the finished line based on the input result of the digitizer 4 and store the data point sequence in the RAM 2.

The mouse 5 gives various instructions to the CPU 1 such as designating the shape of the corner of the seam allowance for a point at the corner of the finish line, and designating the width of the seam allowance for the finish line.
It is configured to be performed on. And CPU1
Is configured to set a data point sequence representing the shape formed by the sewing line based on the input result of the digitizer 4 and the instruction from the mouse 5, and store the data point sequence in the RAM 2.

The display 6 is configured to display the shape of the pattern based on the data point sequence representing the shape of the finished line and the data point sequence representing the shape of the sewing line. Further, the display 6 during pattern making is configured to display a plurality of seam allowance shapes and seam allowance widths as shown in FIGS. The plotter 7 is configured to print the shape of the pattern based on the data point sequence of the finishing line and the data point sequence of the sewing margin line.

Next, the overall flow of the pattern making process will be described with reference to the flowchart shown in FIG.

First, the shape of the finished line is input by the operator clockwise from the point P ₁ using the digitizer 4, and the order in which the shapes were input (P ₁ → P ₂ → P ₃ →
(P ₄ → P ₁ ) is automatically stored in the RAM 2 (step S1, hereinafter simply referred to as S1 and the same applies to other steps). Then, based on the input data point sequence, the CPU 1 displays the finished line of the pattern paper on the display 6.
(S2). Then, the corner of the finish line displayed on the screen is designated by the operator using the mouse 5 (S3). The CPU 1 automatically displays, on the display 6, a sewing allowance arranged around a corner having substantially the same direction as the specified direction of the corner (S4).

Next, the width of the seam allowance and the shape of the seam allowance for the designated corner are designated by the operator using the mouse 5 (S5). When the processing for all the corners is completed (S6: YES) and an instruction to set the seam margin is given, the CPU 1 determines the sewing line from the data point sequence of the finished line and the designated corner, seam margin shape and seam margin width. A data point sequence is set (S7). When the printing of the pattern is instructed, the pattern data based on the data point sequence of the finishing line and the data point sequence of the sewing line is output to the plotter 7 (S8).

Next, the process of designating the seam allowance in S4 when a seam allowance is added to the pattern shown in FIG. 5 to which no seam allowance is added will be described in detail with reference to FIG. FIG.
Is a parallelogram P ₁ P ₂ P ₃ P ₄ having 65 degrees and 115 degrees, and one side P in the horizontal direction.
₂ P ₃ is tilted upward by 10 degrees.

First, the vertex P1 of the corner whose tip is directed to the upper right is designated by the operator as the corner to which the seam is to be attached (S3). Subsequently, the CPU 1 sets the pattern P ₁ P ₂ P ₃ P ₄ surrounded by the finishing line to be composed of clockwise vectors, and sets the vector P starting from the point P ₁ of the designated corner. An angle A ₁ (= 105 degrees) between ₁ P ₂ and a half-line L ₁ extending rightward in the horizontal direction from the point P ₁ is calculated (S20). Since the corner A ₁ is 105 degrees, to less than 45 degrees 135 degrees (S21: YES), CP
U1 displays the four seam allowances arranged around the corner with the tip directed to the upper right in a manner that can be automatically designated as shown in FIG. 6 (S22). Next, the width of the seam allowance and the shape “4” of the seam allowance for the designated angle P ₁ are designated by the operator using the mouse 5 (S5).

Next, when the apex P ₂ corners tip facing the lower right is designated by the operator (S6: NO, S3), the vector P ₂ P to start the point P ₂ of the given angular ₃ and the point P ₂ to the right to calculate the angular a ₂ (= 170 degrees) between the half-line L ₂ which extend in the horizontal direction (S20). Since the corner A ₂ is 170 degrees, it is less than 135 degrees or more 225 degrees (S21: NO, S23: YES ), CPU1
Displays the shapes of the four seam allowances arranged around the corner with the tip directed to the lower right so that they can be automatically designated as shown in FIG. 7 (S24). Next, the shape of the width and the seam allowance of seam allowance "3" for the specified corner P ₂ is designated by the operator using the mouse 5 (S5).

Next, similarly, when the vertex P _{3 of} the corner whose tip is directed to the lower left is designated by the operator (S6: NO, S
3) The CPU 1 calculates an angle A ₃ (= 285 degrees) between the vector P ₃ P ₄ and the half line L ₃ (S20). Since the corner A ₃ is less than 225 degrees or more 315 degrees (S2
1: NO, S23: NO, S25: YES), CPU1
Displays the shapes of the four seam allowances arranged around the corner whose tip is directed to the lower left so that they can be automatically designated as shown in FIG. 8 (S26). Then, a seam allowance width and seam allowance shape "4" for the specified corner P ₃ is designated by the operator using the mouse 5 (S5).

Next, similarly, when the vertex P _{4 of} the corner whose tip is directed to the upper left is designated by the operator (S 6: NO, S
3), the CPU 1 calculates an angle A ₄ (= 350 degrees) between the vector P ₄ P ₁ and the half line L ₄ (S20). Since the corner A ₄ is 350 degrees (S21: NO, S23:
(NO, S25: NO), the CPU 1 displays the shapes of the four seam allowances arranged around the corner with the tip directed to the upper left so that they can be automatically designated as shown in FIG. 9 (S27). Next, the shape of the width and the seam allowance of seam allowance "3" for a given angular P ₄ is designated by the operator using the mouse 5 (S5). Then, when the shape of the seam allowance is specified for all corner points (S6: YES), the CPU 1 sets the seam allowance (S8).

As described above, since the shape of the seam allowance that can be specified is arranged around the corner substantially in the same direction as the angle designated to provide the seam allowance, the desired seam allowance can be easily and quickly formed. In addition to being able to specify, input mistakes can be prevented. Also, since the direction of the corner of the display content is similar to the direction of the specified corner, it is not necessary to consider whether or not to rotate the specified corner to correspond to the display content,
The burden on workers is reduced.

The present invention is not limited to the present embodiment, and various modifications are conceivable.

For example, in this embodiment, the direction of the end of the corner of the finished line is detected, and a plurality of types of seam allowances arranged around the corner similar to the detected direction of the end of the corner are displayed. However, the angle of the corner of the specified finishing line is detected, and based on the detection result of the detected angle, the angle of the corner where the seam allowance to be displayed is settable is set, and the display content is specified. The angle may be similar or matched. In this way, when an angle is detected, it may be configured to determine whether the angle is classified as an acute angle, an obtuse angle of less than 180 degrees, or an obtuse angle of 180 or more.

In this embodiment, the finished line is defined as a clockwise vector, and the angle between the vector starting from the corner of the specified finished line and the half-line extending rightward from the corner is defined as the starting point. Although it is detected, the finished line may be a counterclockwise vector, and an angle between a vector ending at a corner of the specified finished line and a half-line extending rightward starting from the corner may be detected. .

Further, in the present embodiment, the CPU 1 automatically displays the seam allowance on the basis of the angle calculated by calculating the shape of the seam allowance. It may be configured to be able to perform the change operation.
