创建参数和公式
; v9 k  p9 V8 P# h( l2 D" L1．创建参数
//初始化CATICkeParmFactory 工厂
; `& V+ N. k" f! _3 @" P% I  {$ xCATICkeParmFactory_var spParmFactory = spContainer;
# l) F+ z% P$ A) t' j* XCATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);

2．创建公式
//创建参数列表

, h9 g3 G$ e3 }7 a& ypList->Append (spParam1);
0 s# G( o" C' \% @* VpList->Append (spParam2);
pList->Append (spParam3);
//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
# b" Y/ C: m! G2 r' w- g- I% ^: hspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
