To provide a design support apparatus configured to design a cutting pattern of a sheet that allows an upper to conform to a shape of a shoe last when thermoforming is performed, a design method, and an upper producing system.SOLUTION: A design support apparatus 100 includes: an input unit 106 that receives shoe last data 1; a processor 102 (computing unit) that computes a cutting pattern 30 of a sheet based on the shoe last data 1 received by the input unit 106; and an output unit 108 that outputs the cutting pattern 30 of the sheet computed by the processor 102. The processor 102 calculates an amount of correction in consideration of a shrinkage direction and a shrinkage coefficient of the sheet, and calculates the cutting pattern 30 of the sheet by developing, on a plane, three-dimensional shape data 2 that conforms to a dimension of the shoe last data 1, to thereby obtain a shape pattern 3 of an upper, and incorporating the calculated amount of correction into the shape pattern 3 of the upper.SELECTED DRAWING: Figure 1 【課題】熱成形を行った場合にアッパーを靴型の形状に沿わせることができるシートの裁断パターンを設計する設計支援装置、設計方法、およびアッパー作製システムを提供する。【解決手段】設計支援装置１００は、靴型データ１を受け付ける入力部１０６と、入力部１０６で受け付けた靴型データ１に基づいて、シートの裁断パターン３０を演算するプロセッサ１０２（演算部）と、プロセッサ１０２で演算したシートの裁断パターン３０を出力する出力部１０８と、を備える。プロセッサ１０２は、シートの収縮方向および収縮率を考慮した補正量を算出し、靴型データ１の寸法に合わせた３次元形状データ２を平面に展開したアッパーの形状パターン３に対して、算出した補正量を加えてシートの裁断パターン３０を算出する。【選択図】図１
