在上一节的基础上，开始创建草图。首先创建草图工厂：
6 \( P: A7 A: A0 U, OCATI2DWFFactory_var sketch2DFactory(spSketch);
5 l4 N9 D9 ?% y6 b下面创建点：
7 D. _4 F  z9 }# ]* ~CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
3 S: b8 i& B! A0 D0 sdouble pt_bottom_left[2]  = {10., 10.};
: P) ]: e; w" v9 Edouble pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
( o" z- T9 p0 A  Z7 [* QspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
6 C$ {% i% U7 c# W8 \spPt_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;
* s2 u  [6 Y, `/ p9 GspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
6 K: X7 J% w' ]; WspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
* _! d4 ^8 G6 _" W8 h0 [. SspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
% P) ?% H* v) ?$ ?) L将线连接起来：
. h4 J' b9 C" d- JCATI2DCurve_var spCurve1 (spLine1);
- x3 U& t, {. i' {5 a3 i; MCATI2DCurve_var spCurve2 (spLine2);
' S8 F& a$ A. d4 B$ }CATI2DCurve_var spCurve3 (spLine3);
' Q/ }# \/ T1 \% p. B: vCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
+ ~$ Q, r" p. w+ ispCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
/ Z/ i/ Z' w  K) J  M: YspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
  @! l" f! n  OspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
1 j' {( v' P4 x% C然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
