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：
) ^* s  L4 y" a$ q  q, N* y3 |CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
& O6 G) `- T2 ?$ ]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.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
# X& r  F* t9 `7 J: S$ E: K# a9 {spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
6 e! s' z3 l% \  lspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
" W0 ]- t& m, a/ t* I/ G- P开始创建线：
- ~  z8 K7 {; L/ {; d+ p3 w9 rCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
  C/ D- f: W! M8 O6 |spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
* r. j( n: t4 x% G) z: z# o# EspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
4 n4 C/ v" K$ N- I/ U# gspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
' |  J  \8 U3 @# n/ ?3 }CATI2DCurve_var spCurve1 (spLine1);
3 _% b9 B" Y$ pCATI2DCurve_var spCurve2 (spLine2);

" O. ]) H) W* \  X6 I- ]# @6 wspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
+ |; K' t- i( |2 U) H! uspSketch->CloseEdition();
! E2 |5 x* f! T2 C3 M7 J5 ~

非常棒，有没有接口之间的关系导图呀
