创建参数和公式
1．创建参数
& S' r' P' _+ Y& U//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
$ U9 q4 R+ s- G$ M& ~4 ECATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
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
CATIParmPublisher_var spParmPublisher = NULL_var;
CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
) c0 s+ [$ e: t  T7 a1 @spParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
3 M! I$ Z0 {& K# h1 A+ T9 HspParmPublisher.Append(spParam3);
2．创建公式
# _9 u3 g! c! }1 m0 w& \//创建参数列表
0 \: B3 L/ Z9 p; z% m! yCATCkeListOfParm pList;
pList->Append (spParam1);
9 P5 R, X+ Z" YpList->Append (spParam2);
# F8 r9 J9 G# i& @pList->Append (spParam3);
4 d( c5 E2 ^( Y! `8 e/ m//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
! i9 `: E/ @# w9 \. {! d3 XspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
; u8 C* w$ E- W% }; U4 j5 V//修改参数进行测试
spParam1->Valuate(0.5);
