创建参数和公式
1．创建参数
//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
, l8 m* U& o+ s$ y! ^2 `5 ~CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
1 ]- {) G# H  X5 zCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
" L+ Q( V7 V  a9 G$ \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
CATIParmPublisher_var spParmPublisher = NULL_var;
CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
9 E8 T) {9 q% W9 O% I  ~3 ^spParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
1 R& G, Q, N9 P9 XspParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
* O+ D, D+ z* ^/ M! ZCATCkeListOfParm pList;
pList->Append (spParam1);
/ d2 E7 W' ^$ c+ ]9 _$ D/ bpList->Append (spParam2);
" g- Y4 H4 l$ t$ J' k8 z' t) \pList->Append (spParam3);
4 ^( x" d, w. v( R% A1 i//创建公式Height = Width + Base
; F* o8 F6 p% W+ r; v. dCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
2 V- @5 B: X7 gspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
5 N+ V! s+ O0 F- r% V* F, }( @//修改参数进行测试
9 v3 L- y& ?& f! fspParam1->Valuate(0.5);
