在上一节的基础上，开始创建草图。首先创建草图工厂：
3 j) t  U6 P. ]) D4 U+ T+ E0 hCATI2DWFFactory_var sketch2DFactory(spSketch);
0 Y) x/ ~' h" Y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.};
: G+ y0 @# q% X1 vdouble pt_bottom_right[2] = {50., 10.};
0 k1 \4 m7 T& d& N3 }+ mdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
* K7 R2 O; O/ S& r0 C) g* F& IspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
% ^+ \+ L) [0 S8 IspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
6 i- Z" Q. m/ H/ e8 }& L+ W& d开始创建线：
( W2 w' E8 }2 R% ECATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
1 R% t- C; R5 Y+ r. R5 I. WspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
' R! T$ c- t0 \: }9 i5 i将线连接起来：
* N3 `7 y- F! y. O6 {2 LCATI2DCurve_var spCurve1 (spLine1);
! ]+ {  R) P" GCATI2DCurve_var spCurve2 (spLine2);
$ i9 q0 |4 E7 F- [0 \CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
0 w; o$ f9 i6 [0 FspCurve1->SetStartPoint(spPt_bottom_left);
6 Q% }6 }% S' jspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
) \8 l7 A. ]# W, e7 b2 F8 Z1 N# dspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
5 \- E8 N0 L( q7 _1 J% |, o- L然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
