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);
下面创建点：
+ M7 ?, e5 z) R8 d: ]' PCATI2DPoint_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.};
double pt_top_right[2]    = {50., 50.};
. n. d2 G/ E- o8 D; a0 gdouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
' l! ~. \0 Q8 espPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
/ r% a0 E: h. P. E% LCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
- M( J0 S8 J& n% hspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
3 V5 G9 |3 G( I8 f; \4 uspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
8 e. W# N1 m* O5 g* g" f; V1 w, a! {将线连接起来：
2 x1 [5 P2 ^1 N5 SCATI2DCurve_var spCurve1 (spLine1);
( A- K6 M2 G7 P/ X' ]CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
. C: d0 R* [( F" i$ NCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
, {& z# W) m0 W" I  V0 e/ p( o2 WspCurve1->SetEndPoint(spPt_bottom_right);
+ o6 C8 M6 d3 ?  F/ e/ u1 A4 XspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
4 _: W2 S+ Y% j# d6 o4 }spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
  `9 g0 O) A2 L$ {% v8 lspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
, J+ Y" s) f5 espSketch->CloseEdition();
% [6 _  l4 J% k3 Y: Z( {; {

+ p# |7 O. `0 S" n

非常棒，有没有接口之间的关系导图呀
