在上一节的基础上，开始创建草图。首先创建草图工厂：
- Z2 T3 B! P* {7 l& BCATI2DWFFactory_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.};
: F* i( Q$ Q3 p- W$ \3 b/ [double pt_bottom_right[2] = {50., 10.};
% j/ ?. w6 }8 |9 U( e& O9 M2 d. e( I( }double pt_top_right[2]    = {50., 50.};
  ~; Z& a/ m( ?" mdouble pt_top_left[2]     = {10., 50.};
2 R3 s! p; o5 Q: U2 ispPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
$ G8 S. @) W% m# NspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
* U# s. u8 H8 U6 \( m6 ~开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
, }+ Y8 B& z$ e) N5 hspLine1 = 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);
: G" x8 {+ ^5 h/ i7 EspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
% h; x- ?* D* \  t+ ]  fCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
% B* I" u% a0 y/ k+ n4 Z% xCATI2DCurve_var spCurve4 (spLine4);
7 C% B1 S7 i  O  A8 ^spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
& d3 t6 y  z. v: \* ispCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
9 s4 T' m' i8 G8 a/ ^spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
+ I' f+ }! `( f# [spSketch->CloseEdition();
; k" k2 J$ l$ t! `- c0 A* h. l

非常棒，有没有接口之间的关系导图呀
