在上一节的基础上，开始创建草图。首先创建草图工厂：
! x0 M* y, {0 Y/ @CATI2DWFFactory_var sketch2DFactory(spSketch);
# K# @+ z. b" i( n' h/ @$ L下面创建点：
3 s. p9 S$ W, Q9 ?7 F& dCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
; q  Z3 n( p, V: V8 H+ E! R+ W8 adouble pt_bottom_left[2]  = {10., 10.};
  B0 F, T: m( Sdouble pt_bottom_right[2] = {50., 10.};
5 V5 r. j6 V0 x% q3 n# R5 g; [" sdouble pt_top_right[2]    = {50., 50.};
8 O& z$ B1 r; e6 Ldouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
. H" j. z; l  S4 a- P6 h3 OspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
2 B" Q- F1 w$ g% M% SspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
/ s- a0 o3 M3 XCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
6 `  q/ X4 J: [, R. H1 C1 VspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
! M* }1 ~+ X% \$ V1 t4 G0 ~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);
& h+ L: z( V& ]% D将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
( j! R4 J8 N6 u! Y0 a2 ]" J5 LCATI2DCurve_var spCurve2 (spLine2);
% f9 d# ]5 t1 h2 s/ P* YCATI2DCurve_var spCurve3 (spLine3);
3 d: h+ }+ X8 oCATI2DCurve_var spCurve4 (spLine4);
& d. M8 q( r0 n+ P5 tspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
- O3 O+ P: d. f& j! f( {spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
. h6 c1 N& ^$ T$ ]1 K, V  |spCurve4->SetEndPoint(spPt_bottom_left);
) Q. Q. C2 `) i$ X然后退出草图：
/ b6 l% L* ?8 mspSketch->CloseEdition();
8 o1 i! ?7 i. B, m

/ F7 L- G6 K! D- i. H: U

非常棒，有没有接口之间的关系导图呀
