在上一节的基础上，开始创建草图。首先创建草图工厂：
/ I; `6 |, B$ k5 d) z) {' cCATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
1 i  \6 W- M% n+ xdouble pt_bottom_left[2]  = {10., 10.};
6 R3 H2 \& y7 y, q* \) ?2 H/ ]double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
1 v6 l: [; {$ _' Y0 dspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
# A3 c3 u6 H+ Z& w3 N+ QCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
8 n7 i* M2 p6 q/ Z4 Q: Y1 h* \0 N( c% M: |spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
9 a8 e' ?  k2 P( q4 J# A4 zspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
6 [; a  {, B% J- a, x, M1 uspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
* ^; U# e( t# V& w1 eCATI2DCurve_var spCurve1 (spLine1);
& t0 m$ z; Y, Z9 c" Z5 b+ mCATI2DCurve_var spCurve2 (spLine2);
  V, L3 n5 N- J' F- mCATI2DCurve_var spCurve3 (spLine3);
: l' N5 S9 e) P: I/ \$ iCATI2DCurve_var spCurve4 (spLine4);
0 S( A  L& \" l2 _spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
* m. w( z7 M2 K* G- ]& }spCurve2->SetStartPoint(spPt_bottom_right);
( v: p& F! I; m( q! O+ hspCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
2 n2 @- [4 e  U- CspSketch->CloseEdition();


3 p% O/ s* d, j( I2 ?6 _7 K+ D

非常棒，有没有接口之间的关系导图呀
