创建参数和公式
1．创建参数
  c' _/ K" b$ `1 _0 }//初始化CATICkeParmFactory 工厂
  h& h& F$ h. K  _CATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
9 f; r1 M2 W: ?9 l% {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
// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
3 Z' B+ z' p1 S- _& ]CATIParmPublisher_var spParmPublisher = NULL_var;
( u/ C9 v% i. q0 S1 vCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
) y! v/ L3 j9 {- C' |spParmPublisher=
4 v* O6 h* ~; aspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
: N. c3 W# L7 p% c1 [. RspParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
' M: ^7 A  j8 r2 F  M3 D$ ?CATCkeListOfParm pList;
9 E/ W8 p! Z7 c' GpList->Append (spParam1);
( Q# L( ?; |( B8 X' j1 C/ fpList->Append (spParam2);
  ?6 J1 l& f( a) K! g& l0 W; HpList->Append (spParam3);
//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
/ j1 F3 |0 e0 dspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
# m/ V+ u! ?; k! BspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
. F8 V3 [, m! m" dspParam1->Valuate(0.5);
