创建参数和公式
2 N9 M6 t. f" a, q/ u. W6 @1．创建参数
1 ?4 h6 D# |' b$ Y" N- {% v//初始化CATICkeParmFactory 工厂
% V( x( |4 M: v2 q1 U( yCATICkeParmFactory_var spParmFactory = spContainer;
, R4 R1 c3 J: vCATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
3 {; W# Z3 I; |) z1 jCATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米

spParmPublisher.Append(spParam1);
7 h  \3 {5 x: }* P- }4 GspParmPublisher.Append(spParam2);
spParmPublisher.Append(spParam3);
2．创建公式
//创建参数列表
CATCkeListOfParm pList;
pList->Append (spParam1);
pList->Append (spParam2);
pList->Append (spParam3);
//创建公式Height = Width + Base
, B& G" t% U9 ]1 o7 J& MCATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);

//修改参数进行测试
