创建参数和公式
1．创建参数
0 u0 w8 y- B; m//初始化CATICkeParmFactory 工厂
CATICkeParmFactory_var spParmFactory = spContainer;
CATICkeParm_var spParam1 = spParmFactory->CreateLength("Base",0.1);
- U% f  V' [, X8 P' H' Q9 ^CATICkeParm_var spParam2 = spParmFactory->CreateLength("Width",0.15);//长度单位为米
CATICkeParm_var spParam3 = spParmFactory->CreateLength("Height",0.2);//创建长度参数
( ~8 F* ]4 [- q// CATIParmPublisher 与CATICkeFunctionFactory 功能为将所有参数显示在结构树中
# a) Z0 g) u# u& ]4 jCATIParmPublisher_var spParmPublisher = NULL_var;
8 I6 H- a3 H3 Q5 y  N8 cCATICkeFunctionFactory_var spFuncFactory =CATCkeGlobalFunctions::GetFunctionFactory();
( I9 B  P! D7 yspParmPublisher=
% j, [1 t1 K5 I  L9 bspFuncFactory->GetCurrentSet(CATICkeFunctionFactory:arameter,spPrtPart,CATCke::True);
) b5 Q# e3 s$ O0 b( i/ ?spParmPublisher.Append(spParam1);
spParmPublisher.Append(spParam2);
& y0 t& c" |- S; BspParmPublisher.Append(spParam3);
5 {! R5 i; U7 s6 d3 @7 R2．创建公式
//创建参数列表
& |- \: P# {3 C( C, U  c: ZCATCkeListOfParm pList;
( Z, [- ]& W) |6 d/ K/ VpList->Append (spParam1);
; ]& e3 @& N9 n* _1 I9 u- UpList->Append (spParam2);
. ^6 y+ s, j# @+ y$ U- J4 w: j* @pList->Append (spParam3);
//创建公式Height = Width + Base
CATICkeRelation_var spFormula1 = spParmFactory->CreateFormula("Formula","","",
spParam3, pList, "Width+Base", spParmPublisher, CATCke::True);
spFuncFactory->AddToCurrentRelationSet(spFormula1, spParmPublisher);
//修改参数进行测试
6 Y0 y. C+ C$ a) K) q+ ~spParam1->Valuate(0.5);
