在上一节的基础上，开始创建草图。首先创建草图工厂：
3 ]$ B+ q# L! Z/ Q0 M) aCATI2DWFFactory_var sketch2DFactory(spSketch);
0 c! [3 R- l3 B2 s下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
( R1 F/ ^! h( `double pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
/ Y; D) }7 N. U7 ~, r: vdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
# l8 x* e8 W# ^2 w/ l+ qspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
/ y5 o4 u- r, x# U; wspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
$ L; R5 n9 W& |7 r开始创建线：
4 H, h" w+ q4 v- d: ^6 O$ V7 YCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
! @1 Z6 P( L$ b  T! J+ |spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
1 H0 E# U& F2 }, SspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
0 N" W  d' B/ t& Q, \0 R" j' K* PCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
" J' j5 S' u; q  K7 f9 h) A* KCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
. i6 W2 d+ o- v* CspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
7 D& h6 ]' L* Z6 zspCurve2->SetStartPoint(spPt_bottom_right);
* M7 n1 i- C! ^2 ~, tspCurve2->SetEndPoint(spPt_top_right);
2 B+ f/ e5 N3 M1 Y) [spCurve3->SetStartPoint(spPt_top_right);
1 R) C1 r4 u( ]spCurve3->SetEndPoint(spPt_top_left);
, D* c! D6 [7 m: n. E* |spCurve4->SetStartPoint(spPt_top_left);
2 K9 M  p0 P3 }1 m) f5 W2 [1 A4 z$ CspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
7 x- q& Z, U+ w# n: V3 C, pspSketch->CloseEdition();
8 l3 G) t" `# r9 J7 [# O

非常棒，有没有接口之间的关系导图呀
