To automatically and accurately derive the shortest distance between a surface to which a weather strip is attached and a surface with which the weather strip is brought into contact.SOLUTION: A system creates a drawing of a cross-section C passing through a reference point P and orthogonal to a cross-section reference line Ls. The center of gravity G of a weather strip 60 on the cross-section C is acquired, and an attachment surface F1 on the cross-section C is set, based on the positional relation between the reference point P and the center of gravity G, as a line segment having a predetermined width. Measurement direction lines Lm orthogonal to the attachment surface F1 are set. The measurement direction lines Lm are extended from both ends of the attachment surface F1 toward the center of gravity G, and each of the measurement direction lines Lm interfering with a line of a component is set as a contact surface F2. The minimum value between both ends of the attachment surface F1 of distances between the attachment surface F1 and the contact surface F2 in the direction along the measurement direction line Lm is derived as the shortest distance dmin.SELECTED DRAWING: Figure 7

    【課題】ウェザーストリップが取り付けられる面と、ウェザーストリップが当接される面との間の最短距離を自動で且つ精度良く導出することができる。【解決手段】システムは、基準点Pを通るとともに断面基準線Lsに直交する断面Cの図面を作成する。断面C上におけるウェザーストリップ60の重心Gを取得し、基準点Pと重心Gとの位置関係に基づいて断面C上における取付面F1を所定の幅を有する線分として設定する。取付面F1に直交する測定方向線Lmを設定する。取付面F1の両端から測定方向線Lmを重心G側に向けてそれぞれ伸ばすとともに、測定方向線Lmの各々が干渉する部品の線を当接面F2として設定する。測定方向線Lmに沿う方向における取付面F1と当接面F2との間の距離のうち取付面F1の両端間における最小値を最短距離dminとして導出する。【選択図】図7
