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);
! V* b5 Q% \% e, L下面创建点：
5 t) d6 o% D4 I) X* V8 u1 GCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
5 |" @* ]7 j: p7 v3 o2 cdouble pt_bottom_left[2]  = {10., 10.};
: w; T; B: R( f5 w% Z+ I6 qdouble pt_bottom_right[2] = {50., 10.};
7 ]; V1 L" B: p( \; Z  h2 kdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
4 s- M8 X/ G+ f0 F, r# TspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
  w1 e5 B% k  X- Y' KspPt_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;
2 v7 c2 t% [$ ]spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
: K! C& w3 D/ u6 L- RspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
9 f( N- M/ ~# j" QspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
' w/ q# _; d/ g将线连接起来：
0 c& ]* P9 a( tCATI2DCurve_var spCurve1 (spLine1);
/ Z/ P- s; _' E) p, V$ ~2 KCATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
/ g: `  z# E9 v) [( C$ e& O2 zspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
- h4 h4 T0 o- E/ A7 v1 N* aspCurve2->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：
spSketch->CloseEdition();
, k! `5 v9 {0 W' q; l/ r  M1 k

非常棒，有没有接口之间的关系导图呀
