创建参数和公式
1．创建参数
//初始化CATICkeParmFactory 工厂
3 n6 i7 N" _2 G, e8 sCATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
' J4 h/ T8 m( m4 }8 g- D1 tCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
) s6 K3 i- G0 S5 z* S% hCATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
* Z/ A) ]8 W' Z- C* s% ?. m" M// 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();
spParmPublisher=
$ E7 S- C  A. v5 l$ Z# q; N( mspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
% B+ I" Y2 V3 P( V6 U# v) kspParmPublisher.Append(spParam3);
2．创建公式
6 v$ E# q! X5 I//创建参数列表
CATCkeListOfParm pList;
pList->Append (spParam1);
' i% W/ b6 _; j( k1 TpList->Append (spParam2);
! }# ~3 Z1 k# l  p/ o( U  QpList->Append (spParam3);
1 g" s( o4 ^1 s0 |' ~5 [7 V- N$ A5 H$ O//创建公式Height = Width + Base
# A" d( y9 ^, }$ R7 E( X" Z8 ECATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
* n9 G, _% d% H/ l* u, GspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
spParam1->Valuate(0.5);
+ P( n! N2 |# u
' z4 ~! m8 Q& l* C6 T1 d
