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);
0 d: B$ C  I% {$ a下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
* C2 I5 D# p# o, z5 tdouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
$ p' }% [/ S- h, wdouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
4 h( |; S& @7 v1 W- p4 JspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
8 C0 Q' z( {8 e( P& w4 VspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
' a0 M, t  S9 z, d- G9 p开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
% G% L+ A; B8 TCATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
9 m, K3 W5 C  N* fspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
. e. W+ E( Y) U! k+ y0 f然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
