创建参数和公式
4 f; v# ?$ o5 X- a; r9 u1．创建参数
# T+ R( Z) o% A9 A8 M! d0 [; m//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
CATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
1 r3 b# C$ V  o( t0 G) ~// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
# V5 ^, O6 J; Q' Y8 RCATIParmPublisher_var spParmPublisher = NULL_var;
0 Z5 J7 q) q& ^CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
% M5 l! e! U/ \7 jspParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
# U& U$ O- i+ }( \% _/ X$ E/ _spParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式

pList->Append (spParam3);
) Y( {' E3 j, D. t, B5 Q//创建公式Height = Width + Base
4 m' ?* W/ i2 P' V  m: OCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
  a7 {2 C5 ~& x0 lspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
