在上一节的基础上，开始创建草图。首先创建草图工厂：
# }* }1 d2 C" t1 w" B  |' f/ OCATI2DWFFactory_var sketch2DFactory(spSketch);
4 v/ _" c7 T% M0 K/ K+ }- E下面创建点：
& ^! K2 e  m# {, j' _9 S( h" tCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
/ L: p, N! K! r5 r2 I0 L: @& _double pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
5 g- U7 c% ~* ^, z, GspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
7 d- E/ J6 ]: F2 `spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
3 N0 @5 h! i: S- \4 I8 z1 WspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
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);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
% g# D3 Z8 m# _& ~9 f& A" f- `spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
. O  I9 E5 O/ w3 `: bspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
1 S/ }1 r3 K+ x- S/ gspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
" W( i; p# A: W2 WspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
& l4 }* [% L2 u4 `spCurve4->SetStartPoint(spPt_top_left);
  `) Q6 ~& O; m: ^2 y6 M) k( |  Q* @spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
6 T- i' W' n4 Z( h1 v$ i
. o9 V0 Q8 I: b2 m' V0 t

非常棒，有没有接口之间的关系导图呀
