在上一节的基础上，开始创建草图。首先创建草图工厂：
0 N4 h  `- K* g( o/ u% ?7 O1 xCATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
  s6 D* K7 t: GCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
" J! V% R9 v, v( h) r& T& ]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);
9 w/ O. h0 p9 C; H! Y. QspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
5 e( m2 Z% r9 w6 X( x开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
. O3 P# y7 @) |+ RspLine1 = 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);
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);
( ?4 N( l! f7 kCATI2DCurve_var spCurve4 (spLine4);
! n8 F1 \1 @4 hspCurve1->SetStartPoint(spPt_bottom_left);
- S2 Y2 W8 e, a# N, jspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
$ Z2 V  C' Y; n$ m) W) v0 p7 Y1 XspCurve3->SetStartPoint(spPt_top_right);
& B/ l7 x) y9 W" \7 ^spCurve3->SetEndPoint(spPt_top_left);
( |, f( s( w/ b- x  ~* gspCurve4->SetStartPoint(spPt_top_left);
/ }( {4 C; {! P0 M8 qspCurve4->SetEndPoint(spPt_bottom_left);
" G, H; t5 o# |' ]9 Z然后退出草图：
6 I7 H1 O, A$ J* C: V6 LspSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
