创建参数和公式
1．创建参数
//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
2 X( i) Q0 P5 K+ z0 u* \; ]CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
CATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
, B7 t. g( I2 oCATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
7 Z( W+ j3 z% A// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
CATIParmPublisher_var spParmPublisher = NULL_var;
5 C+ s* z9 ?0 D4 T5 P; r; yCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
spParmPublisher=
spFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
spParmPublisher.Append(spParam1);
: O  \8 d6 x. u$ v% yspParmPublisher.Append(spParam2);
1 i# i3 G& o" u6 V6 G" xspParmPublisher.Append(spParam3);
2 a9 N) C& ^- R" o1 n& A" s2．创建公式
//创建参数列表
CATCkeListOfParm pList;
8 h$ o/ F/ s1 O0 U  X6 k) j4 CpList->Append (spParam1);
pList->Append (spParam2);
pList->Append (spParam3);
7 k, U2 B+ N, a2 v//创建公式Height = Width + Base
+ y4 U9 h6 B6 ]/ d3 MCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
1 s+ P' ?/ U; B1 OspFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
spParam1->Valuate(0.5);
