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);
下面创建点：
" {6 A* O- D( G9 g% o7 e: PCATI2DPoint_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.};
& q4 M! N$ t1 r& J. C6 s, @1 n, a1 Kdouble pt_top_right[2]    = {50., 50.};
% b  T+ J: B# P* |2 N7 g8 G8 bdouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
5 t3 W+ f' n, |/ S. F: XspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
' b' N( M. [. i/ Z开始创建线：
: S) C! f  U4 K+ OCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
1 ~; ^. `- Y* a0 kspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
' u7 f/ f- a  B1 TspLine2 = 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);
将线连接起来：
& G5 j# @4 y! C. f4 S% }CATI2DCurve_var spCurve1 (spLine1);
- Q0 P) i: w8 ?3 j+ h: F0 Q0 [CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
$ J& h$ ]$ _2 }! u/ _% [spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
- Z( Q" u: t$ p+ e0 f, JspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
1 R8 w7 H' i/ |3 KspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
& X. ?! I, O5 H然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
