在上一节的基础上，开始创建草图。首先创建草图工厂：
. m3 ?9 h- L, Y( @" y( nCATI2DWFFactory_var sketch2DFactory(spSketch);
5 ?+ D: t* t5 [7 P9 C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.};
2 b) v8 f5 t+ b3 Adouble pt_bottom_right[2] = {50., 10.};
( a- A3 T" c" |- f2 S* k. }double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
# b3 x. V# w7 j+ X( X- Q) QspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
8 D1 b5 \* G; m1 c开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
1 H' G4 `9 r; k9 aspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
: K" w: ]; D' R4 qspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
2 C: }) p7 J/ Q3 [9 \spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
) k- Y$ H8 |* h: U& D9 V* cCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
. i/ Y/ A  B  ~* O, w$ ospCurve1->SetStartPoint(spPt_bottom_left);
% x9 ?+ G' |9 t7 E! g$ x" Z, `spCurve1->SetEndPoint(spPt_bottom_right);
! R  p5 F3 [( NspCurve2->SetStartPoint(spPt_bottom_right);
# l2 |& |2 n2 ^  Q: O5 ]$ x& V- ~spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
9 r* P7 t  e2 C7 n# {, g8 b) s( ospCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
$ |! V+ i6 n3 S2 Q+ b
- s9 s' K! c$ E& J7 S$ q

非常棒，有没有接口之间的关系导图呀
