In addition, a calculation program or the like for determining the sewing allowance, the ratio of the texture, or the dimension of the pattern piece according to the shape may be supplied. When a storage device is used, a plurality of patterns may be stored, and a desired pattern may be selected. In this case, the information on the pattern may be separate pattern information for each number of pieces, or only one piece having the same shape may be supplied, and a means for inputting the number of pattern pieces will be described later. Furthermore, a user may be allowed to input the number of pieces arbitrarily.
The means for providing information on the size of the work is usually an input device by an operator or the like, by which the size of the desired work is input.
The calculating means may calculate the size of the entire material in addition to the size of each material piece.
The calculation program is a program for calculating these required sizes, and is configured to perform calculation suitable for each pattern pattern.
Information on the number of pattern pieces of the patchwork may be supplied as information on the pattern, or a means for separately inputting the number of pattern pieces may be further provided. In this case, the calculating means calculates the required size of each material piece based on the information on the pattern and the input number of pieces and the information on the work size.
The size of the material piece by the above calculation is generally the size of the pattern piece of the work plus the sewing allowance and the kinks.
The output means is typically an image display means, an audio display means, a print output means, or a combination thereof, but any other output means can be used.
The means for determining whether or not the calculated size of the material piece is within a predetermined range typically determines whether or not the size of the sewable piece. This determination may be made by the user, and a means for inputting the determination may be provided.
