天圓地方不銹鋼鈑金放樣下料方法
1.先實際尺寸畫出側視圖和俯視圖，然后把俯視圖上的1/4圓弧等分成3份。再把分出的各點（1、2、3、4）用直線（a、b、c、d)與F點相連。（步驟相對應1-1圖與1-2圖）
2.再畫一條直線，取一點I,量取高度尺寸以I點為起點在直線上標注一點J。然后過I點畫一條與其垂直相交線，量取直線a的長度以I點為起點在線上標注一點K，再量取直線b長度以I點為起點在直線標注一點L 。用直線e把K J兩點相連，再用直線f把L J兩點相連 。（步驟相對應1-3圖）
3.① 以方頭一邊的長度畫出一條P Q直線，找出P Q直線中心點O畫一條與其垂直相交線。
② 以點Q為圓心，直線e為半徑（以下稱Qe圓弧）在垂直相交線上畫圓弧相交于點7，用直線把7 Q兩點相連。
③ 以點Q為圓心，直線f為半徑畫圓弧（以下稱Qf圓弧）。再量取俯視圖中的點1與點2之間的弦長（以下稱1～2弦長）為半徑，點7為圓心畫圓弧相交于點6，用直線把6 Q兩點相連。
④ 以點6為圓心，1～2弦長為半徑畫圓弧與Qf圓弧相交于點5，用直線把5 Q兩點相連。
⑤ 以點5為圓心，1～2弦長為半徑畫圓弧與Qe圓弧相交于點4，用直線把4 Q兩點相連。
⑥ 以點Q為圓心，線段PQ為半徑畫圓弧，再以點4為圓心，線段7Q為半徑畫圓弧相交于點S，用直線把Q S兩點相連。再用直線把點4與點S相連。
⑦ 以點S為圓心，線段Q4為半徑畫圓弧（以下稱S4圓弧），再以點S為圓心，直線f半徑，畫圓弧（以下稱Sf圓弧）。
⑧ 以點4為圓心，1～2弦長為半徑畫圓弧與Sf圓弧相交于點3，用直線把3 S兩點相連。
⑨ 以點3為圓心，1～2弦長為半徑畫圓弧與Sf圓弧相交于點2，用直線把2 S兩點相連。
⑩ 以點2為圓心，1～2弦長為半徑畫圓弧與S4圓弧相交于點1，用直線把1 S兩點相連。
4.以點4為圓心，點O、4之間的距離為半徑畫圓弧（以下稱O4圓弧），再以點S為圓心，O Q兩點的長度為半徑（即是1/2邊長）畫圓弧與O4圓弧相交于點T，用直線把S T兩點相連，再用直線把點1與點T相連。（步驟相對應1-4）
5.用線段把1 2 3 4 5 6 7依次連接，即得1/2展開圖。（步驟相對應1-4）
6.如要完整展開圖即可按以上步驟連續把另一半展開圖畫出（步驟相對應1-5）
