在上一节的基础上，开始创建草图。首先创建草图工厂：
" J1 l( j! l* M8 b( ICATI2DWFFactory_var sketch2DFactory(spSketch);
: m, x) o5 I5 x  q# q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.};
double pt_bottom_right[2] = {50., 10.};
) m$ d. _- Q4 \  `8 tdouble pt_top_right[2]    = {50., 50.};
# {, T) F; C' Z7 E# e" H1 y0 adouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
- i' p8 {, g- Z9 \0 FspPt_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;
1 i/ K3 E: G! x% Y' G* g7 F8 A- Z: PspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
  Y0 i& F$ {, X9 V: ~8 gspLine2 = 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：
5 v" @8 ?8 N0 ]1 qCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
; e; u; o$ f$ P  f' r, J+ kCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
, o9 u: P1 p" W: j3 I' HspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
4 r  b) s- D1 |( k* k/ s1 n$ VspCurve2->SetEndPoint(spPt_top_right);
/ ~' B4 m: A$ Y, t# Z! OspCurve3->SetStartPoint(spPt_top_right);
( S* U( z( G. r( N/ V; ZspCurve3->SetEndPoint(spPt_top_left);
6 j  R8 [0 n+ j4 I; P! JspCurve4->SetStartPoint(spPt_top_left);
0 N+ \( D: l& a% D/ B0 WspCurve4->SetEndPoint(spPt_bottom_left);
5 k2 A# w0 r% T4 v4 q  X: n然后退出草图：
! Z* {: f( ?: @6 {spSketch->CloseEdition();
) d) J! k2 ?/ k+ L- l, B
0 }1 h: R$ }2 ?/ ?7 r
$ ?4 e+ v8 h' q3 W" Y- q

非常棒，有没有接口之间的关系导图呀
