在上一节的基础上，开始创建草图。首先创建草图工厂：
CATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
* U* Z/ N: D" P# b; |) S7 hdouble pt_bottom_left[2]  = {10., 10.};
# I7 ?: J) R5 b4 zdouble pt_bottom_right[2] = {50., 10.};
. q1 n8 @/ N- @4 d* a3 z: E( odouble pt_top_right[2]    = {50., 50.};
$ ~4 |  {1 ~% _' V% Jdouble pt_top_left[2]     = {10., 50.};
9 u: _5 c% F( q. o8 B2 p- pspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
- F" V+ p3 J+ W  ]' {开始创建线：
7 P8 X' o2 z4 Y' I* z0 C$ x$ PCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
2 w9 G) N* _8 F* V5 z) [" e4 ]; BspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
( A; F, j2 [7 p/ [- D+ WspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
' p; S3 l  D8 d- W8 XspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
6 |( z0 \! n" T% z! e3 \* u7 c6 nspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
" V% J) X( n. L. wspCurve1->SetStartPoint(spPt_bottom_left);
- P; N# J/ F- r2 PspCurve1->SetEndPoint(spPt_bottom_right);
5 i6 e4 l; C/ v: D7 V4 G$ O! NspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
1 l! `' a9 Q1 |- h6 p- g" J1 G然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
