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);
9 t' z- S: l3 z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.};
2 r3 u# a# [3 xspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
2 d# c5 v/ l9 C: J& w$ ?spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
# v* _3 I" c' ]1 I' h* b- d% s开始创建线：
& H  c6 ?5 [5 z9 H& B( Y! WCATI2DLine_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);
将线连接起来：
% x' G& y- v! s/ fCATI2DCurve_var spCurve1 (spLine1);
6 Z- Y' z9 W! N* mCATI2DCurve_var spCurve2 (spLine2);
+ e1 \# {6 G: I  C" t7 m% j& FCATI2DCurve_var spCurve3 (spLine3);
$ S9 x% h# c. g/ V9 tCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
. ?# O9 L  ^) \1 C" UspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);

/ Q% B; X" W: f( T7 SspCurve4->SetEndPoint(spPt_bottom_left);
+ E9 `: w8 b" q% f" Q- z% g然后退出草图：

非常棒，有没有接口之间的关系导图呀
