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);
2 W' N, ?( ?4 C1 c下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
9 q* x# B  Z( @8 }double pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
* w2 ]& Q" M! c/ w. G* L& V. pdouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
; u; x+ Z8 q4 |2 AspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
( |  r# ?& x2 {: nspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
% N3 u9 c0 Z; ~; Q% w2 L1 |4 `3 wspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
, `0 L- |$ D% _2 f! B4 lspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
( s3 ?. j: f. n; _, @$ Q7 W% a将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
4 L/ Q7 V2 E0 L  X' t6 d  iCATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
8 a3 l5 G$ J& n2 \( o' s7 \spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
! F# @/ e8 h  H) {! zspCurve3->SetStartPoint(spPt_top_right);
: O' S" m+ r8 M$ TspCurve3->SetEndPoint(spPt_top_left);
9 X3 g2 @! E% a) [* ?spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
# H7 q8 W5 U' w; _$ x# d1 |然后退出草图：
; J% E; {' b# V4 ^# X7 @spSketch->CloseEdition();
" ^7 |5 g5 f8 e

非常棒，有没有接口之间的关系导图呀
