创建参数和公式
7 B- I: H5 c: B2 }* Y6 n1．创建参数
- ]6 s' y: K: e  h( G' b1 T1 B//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
CATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
- l9 |* c$ e0 P# t0 jCATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
5 F- J# F- d/ G2 u5 w6 ?+ }// 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=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
4 |' ^: l: S; _0 k  ]' M9 WspParmPublisher.Append(spParam1);
: R8 Y$ C5 ?, PspParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
8 n. x- G+ m2 K; KCATCkeListOfParm pList;
. a) q1 e7 \9 q6 r: {" @1 upList->Append (spParam1);
pList->Append (spParam2);
pList->Append (spParam3);
//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
# l( R  B! d7 h2 J  y) ^7 {//修改参数进行测试
- i1 J/ W9 h! I; o  b/ tspParam1->Valuate(0.5);
