创建参数和公式
1．创建参数
. r1 h9 @" w: R' _0 E/ `9 [" H& T//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
! _5 L6 r! P( c4 H! v4 y5 K' GCATICkeParm_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
+ ?+ l1 |& v* o" D4 k5 W// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
" Y7 b) b$ G4 n) K8 R- {CATIParmPublisher_var spParmPublisher = NULL_var;
( P7 T4 K- Y  C$ ^: LCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
spParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
9 P5 l- S* k5 I9 u, o; C: s7 Y: ]spParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
CATCkeListOfParm pList;
8 H, ?$ @: s7 o' R2 M) X- ^1 bpList->Append (spParam1);
pList->Append (spParam2);
pList->Append (spParam3);
4 G: o; E# T; r+ A1 k% K- X5 n& C% a//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
8 z( a) K2 I2 R5 D& e* KspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
$ S7 R: K& h9 y$ T& Z, o& P//修改参数进行测试
8 |' U! Q; E( V4 NspParam1->Valuate(0.5);
