创建参数和公式
1．创建参数
9 D1 f# a4 e% x( g  A//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
CATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
& E5 `0 t- K2 BCATICkeParm_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();
3 l+ `7 c; \7 Z) k& kspParmPublisher=
/ P& n; t! f" r% r/ v$ Q7 nspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
4 N; M# L5 o% i3 x+ zspParmPublisher.Append(spParam3);
2．创建公式
$ S* D8 P5 T3 M# g) l( {- C//创建参数列表
CATCkeListOfParm pList;
pList->Append (spParam1);
  L3 P  J3 I' {% ]. HpList->Append (spParam2);
pList->Append (spParam3);
, h$ B9 S6 s8 z//创建公式Height = Width + Base
; p" l2 {( Y$ f8 W9 F3 LCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
! ]. m* N5 D' M' q+ r7 I- ospParam1->Valuate(0.5);
