创建参数和公式
1．创建参数
//初始化CATICkeParmFactory 工厂
; G  a! k4 J8 ]' n4 I% \* U' JCATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
  ~3 x# V) M0 Y5 JCATICkeParm_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
, ]* n8 P0 U1 X5 C8 j// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
, C/ d; F. H/ y( fCATIParmPublisher_var spParmPublisher = NULL_var;
CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
spParmPublisher=

. t. t6 T% r$ |7 qspParmPublisher.Append(spParam1);

/ V7 q" Y3 Q& @& W5 B6 ~9 I$ K2．创建公式
//创建参数列表
CATCkeListOfParm pList;
) G& s' ]* [" b( B5 p; E+ cpList->Append (spParam1);
pList->Append (spParam2);
( {6 U  a  P8 W# v: spList->Append (spParam3);
//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
: e2 u3 X, n, A: _7 KspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
  S/ O: t* p) V* i" t' bspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
spParam1->Valuate(0.5);
