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);
3 j8 p) z1 a5 x9 Y2 O7 c下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
3 @" _$ J( V4 ]% Edouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
' J( H3 i) v# Cdouble pt_top_right[2]    = {50., 50.};
& s; H) D2 t! C9 z0 _- H$ ?% `double pt_top_left[2]     = {10., 50.};
* L  E; \( Q5 ?  m2 v# |# aspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
/ n# X, R6 Z# a. y& f) \spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
9 j' a) |( c/ Q" i开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
( N8 w5 T1 ]1 M& z2 @- xspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
- s  z2 O) f% [* }# g0 m/ zspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
5 F  S) z5 c( @将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
/ d; G' l% x9 M% C; W$ V4 {CATI2DCurve_var spCurve4 (spLine4);

9 U/ \+ R: z. \3 JspCurve4->SetEndPoint(spPt_bottom_left);
% `" t' O2 B7 x+ r5 f1 g! o然后退出草图：

非常棒，有没有接口之间的关系导图呀
