创建参数和公式
1．创建参数
0 |& A. s6 [* ~7 f+ v6 {//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
) }8 p# m. G; O& l- KCATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
CATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
CATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
1 L1 e7 b! t  x  B// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
CATIParmPublisher_var spParmPublisher = NULL_var;
CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
spParmPublisher=
7 v0 i$ F; y( p( e4 aspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
0 x6 {# p8 T7 V/ BspParmPublisher.Append(spParam1);
# I- E. U0 ]8 ~5 O1 OspParmPublisher.Append(spParam2);
$ U! |! A/ g2 J! H* e9 KspParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
CATCkeListOfParm pList;
6 O! L* F$ _. b% d5 A4 apList->Append (spParam1);
: J/ R' L! Z) {% P; r- |pList->Append (spParam2);
: k# B- ], c2 ~/ I9 ppList->Append (spParam3);
0 t8 f; U# i6 j2 o) G4 P  A//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
0 O1 R, H& s' H, Q& O6 u" @spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
4 Q4 ^5 b5 P& B: e! R# @9 I* h//修改参数进行测试

$ i! f/ t, O( R+ W/ W) a
