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：
8 x2 D) p% B) C9 W, w7 j3 iCATI2DPoint_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.};
* l9 `: v0 Z1 `2 L0 d* t. |double pt_top_right[2]    = {50., 50.};
. P# O- {9 z3 q* b4 N/ idouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
4 C. `2 ^: A2 h5 D6 A  PspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
: Y9 a  _; a- OspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
2 x& f1 \& u; M  m7 R' cspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
0 ~: d) T( D5 W# Q) f6 M开始创建线：
3 q# d% _" M: TCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
" |, E, y& J: ]2 s/ }- `" `spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
5 d) N4 C3 m2 A+ x$ ^$ f, WspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
  o. R' z9 `  fspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
8 {* Z  ]7 X: [9 yspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
8 L$ d: d; M: \) v7 s: CCATI2DCurve_var spCurve1 (spLine1);
6 V2 F! p5 S8 [4 oCATI2DCurve_var spCurve2 (spLine2);
3 @: ?) Q4 ~' ^2 B+ |0 L7 zCATI2DCurve_var spCurve3 (spLine3);
( L0 L8 ]. m+ R  N* T- J, GCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
2 Y2 K1 k- {6 _' u9 u3 g% j8 j' UspCurve1->SetEndPoint(spPt_bottom_right);
, s* c5 s: z. k1 j7 f1 W0 Q- j) X' `spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
4 [& r/ k1 r% u, y$ ZspCurve3->SetStartPoint(spPt_top_right);
0 w6 }9 ~; r# R- m7 espCurve3->SetEndPoint(spPt_top_left);
( W3 v' D7 r8 CspCurve4->SetStartPoint(spPt_top_left);
( h: o$ y. F5 h! ZspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
+ b+ n* [5 C$ Y5 K- }spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
