创建参数和公式
* U( W6 H! j9 Z; P/ i  B9 n1．创建参数
//初始化CATICkeParmFactory 工厂
& m) K/ c. D! _% n# E' ?# X. iCATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
0 k+ g' p0 T1 P' P, iCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
; o, i9 }4 Z/ h# LCATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
: |; d+ A8 H' U// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
1 O+ W8 T# u( l, {1 \! z! k  D$ ~CATIParmPublisher_var spParmPublisher = NULL_var;
  @1 O9 D& v4 B! q+ I$ ?% d: i# _' rCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
spParmPublisher=
6 i* c9 Q+ q( rspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
& k  G9 `, {' ZspParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
4 v- K/ H, z9 y& i3 bCATCkeListOfParm pList;
pList->Append (spParam1);
pList->Append (spParam2);
5 ?, e$ l& j5 C! GpList->Append (spParam3);
5 _6 T! a: Z* r% ^& E; G2 n//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
spParam1->Valuate(0.5);
