在上一节的基础上，开始创建草图。首先创建草图工厂：
+ M/ N. r) O; ZCATI2DWFFactory_var sketch2DFactory(spSketch);
. }$ N! f% d9 K: p# G- H( E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.};
( T! ]9 l& x! ]) m; B2 t9 B4 Adouble pt_bottom_right[2] = {50., 10.};
+ w/ y6 M& l6 ~# m0 ^1 J* bdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
) k' }+ K# \' b0 `' a0 }spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
' m# K& k! ~* O  j- V" B, `spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
$ n& m, z1 C- g9 }spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
6 X# X- t* e) E$ r) R3 W, x6 q+ wCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
- {/ F8 g0 ]7 |1 `% P1 xspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
! }( n4 V  [) ?- B) ^+ O将线连接起来：
# H) A, ]" A- uCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
! a+ E7 I' U5 ^0 F; c- d" \3 cspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
) G* ?: @6 \: r; Y! T- _spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
# m  f% e, b4 X% AspCurve4->SetStartPoint(spPt_top_left);
9 |# ^2 \3 f# f1 p2 J/ z) wspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
