创建参数和公式
1．创建参数
  E) I2 `, U2 I, A1 F* o5 q/ Y+ ]//初始化CATICkeParmFactory 工厂
7 t; g7 p( Z& `5 X% _% dCATICkeParmFactory_var spParmFactory = spContainer;
: I8 ?. v0 [; b! z. iCATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
4 f6 ]8 M. v/ H- X; pCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
0 W" X* a( m& u8 d! w* [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
" }; b" V: b* e& {3 Q/ fCATIParmPublisher_var spParmPublisher = NULL_var;
5 F8 h8 q: r# G9 j% h& Q$ }# mCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
/ r$ W" N5 k8 U2 @8 J. [5 IspParmPublisher=
4 `, }( z" V$ ]spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
6 k& O7 C2 I* F/ _/ XspParmPublisher.Append(spParam1);
: k* z6 `! U, `! d  PspParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
; {" h/ |1 I$ E# S; I//创建参数列表
& m# z7 \5 I' }) K8 q* z$ ]6 J9 BCATCkeListOfParm pList;
pList->Append (spParam1);
pList->Append (spParam2);
+ V) W( `: |: M3 }pList->Append (spParam3);
8 B6 h( x% O+ V1 g2 E//创建公式Height = Width + Base
% k2 T$ a; Z. x8 E0 l1 c# {8 FCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
2 X9 u6 m6 A/ w  D& `2 IspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
% W7 y( ^# L+ b2 }$ [& nspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
spParam1->Valuate(0.5);
