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);
4 k7 Y1 G  t3 u. V+ F) T- X* H下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
: }% x; E6 ?! j. _% H" p5 D1 P0 mdouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
3 `5 c2 K+ b9 L3 l0 }" C  Idouble pt_top_left[2]     = {10., 50.};
7 E3 @- _0 J* `2 K( n4 x( ]spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
. d/ `4 p; R# Y, espPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
' n6 [& ?0 N! EspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
! E+ L; @: R) z7 j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);
0 }: y0 A  c. h5 R( uspLine3 = 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);
$ k3 s/ D) r: [" u/ m/ lCATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
8 ]# ^! i# {' QspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
' [6 |$ V; ~8 FspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
% i3 u5 d! Q/ m0 ~; wspCurve4->SetStartPoint(spPt_top_left);
spCurve4->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
