在上一节的基础上，开始创建草图。首先创建草图工厂：
CATI2DWFFactory_var sketch2DFactory(spSketch);
) G7 N$ h& }  Q- ]/ ^$ r/ k下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
& a& G; l; S! r4 H! AspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
. C" e( n) B7 h+ vspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
9 {6 ]& G- U4 K  e2 F7 E& gspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
+ |- D) D# l6 ?! O! m开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
8 _& j9 r' B8 ?- ?将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
$ l# O0 N" U1 C: eCATI2DCurve_var spCurve2 (spLine2);
- p. X) q* _3 @% {: wCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
. F6 w9 _8 W. F- LspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
5 t: N6 a' X: u  Z1 QspCurve2->SetEndPoint(spPt_top_right);
" r* ]/ y8 B  f" y- D3 uspCurve3->SetStartPoint(spPt_top_right);

spCurve4->SetStartPoint(spPt_top_left);
& w8 j$ c9 Z1 Q8 h, h" h4 }6 R5 c" [spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
  H! h+ G0 o1 f9 c0 U- gspSketch->CloseEdition();
% C/ l4 `( b  e1 B& n  K& z0 W! V
- ?3 M8 @& I' A% a: X

非常棒，有没有接口之间的关系导图呀
