在上一节的基础上，开始创建草图。首先创建草图工厂：
; X* V9 S! B% }) ]8 B/ z0 ~CATI2DWFFactory_var sketch2DFactory(spSketch);
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.};
0 O  Q* h) a& \2 Hdouble pt_bottom_right[2] = {50., 10.};
# b6 r3 G! O0 sdouble pt_top_right[2]    = {50., 50.};
) T- }/ ~* _0 f. K* a2 w' Idouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
% x  Z3 B  Q: I  Q  N! espPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
$ y4 ~/ \1 J0 mspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
3 r2 p; Z9 i6 q开始创建线：
8 O3 u0 E. K  A- l$ z; W* VCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
5 x; [8 O& ~- w& ?8 K! C/ e; \spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
6 ?( m  W; v3 YCATI2DCurve_var spCurve1 (spLine1);
" C% ?8 Q+ l. D5 uCATI2DCurve_var spCurve2 (spLine2);
* H) q- v: r' D2 f+ ], kCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
. C; D! F- H5 m, Z  B$ N! Z( P" qspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
& t, o/ Y6 Z% D8 Z* ]spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
/ J8 @$ s# @1 D$ PspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
; g7 O) f3 \% _spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
