创建参数和公式
1．创建参数
$ x! X8 u& `2 z) t: m& }- R//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
7 m  m) D- y2 ?! m. i/ ?" }CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
0 \+ G% R2 p# ~( A" @1 O  zCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
8 p8 I' X1 C! A/ c- wCATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
$ ~1 N8 J/ p0 {* Z  ~! L* X# A$ Y// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
4 J4 J- c/ {7 Q: }9 pCATIParmPublisher_var spParmPublisher = NULL_var;
CATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
: x* x9 D' o2 KspParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
' L( I6 V* g& j5 e0 H- CspParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
/ A5 Q0 q6 t2 Q* V+ XspParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
1 b! [( y& T: N7 ACATCkeListOfParm pList;
pList->Append (spParam1);
, X. I1 [, V* U* C  C. jpList->Append (spParam2);
/ \0 l& A6 G( O0 x" x; Y& j3 C$ b8 spList->Append (spParam3);
//创建公式Height = Width + Base
. n: J4 q8 D0 R- F/ P2 zCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
' G0 W2 n9 W+ f, g. mspParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
; g2 s! S. l9 u: R& b: e2 w9 xspParam1->Valuate(0.5);
