在上一节的基础上，开始创建草图。首先创建草图工厂：
( M7 D# e. c9 i& kCATI2DWFFactory_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.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
  U3 H) P1 k0 v0 Y( ?spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
& ]+ y, i* |3 C' F0 pspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
9 {: c6 j' h+ T1 U6 ]$ I1 ~spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
- S/ w7 u6 v0 U& ~spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
' H* l3 z  Y3 {/ w8 x+ x开始创建线：
! I! J8 \& r. f  ~9 uCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
/ T( B4 z' G- A0 f. @0 ^( CspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
! F; {, R2 v% i, SspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
- U6 P8 X; T6 h$ GspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
  S5 {* ]+ W( Y: F0 m: z/ M, P( [. B将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
( l4 P$ C# G" l; F! Y9 zCATI2DCurve_var spCurve2 (spLine2);
, w' |, ~$ q* m; aCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
" S3 q, i3 S1 N  R5 y& G: ZspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);

9 G9 h; r. _% j2 `4 WspCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
; G) W8 _) t4 x4 B  X! R; YspSketch->CloseEdition();
, ?$ S4 [: o# x: }* C/ a

' w3 f; W: H) i# g' i

非常棒，有没有接口之间的关系导图呀
