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：
: j5 m0 {; w* b, gCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
! X6 j4 w+ X& u  E) F/ I7 l- ddouble pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
, Z. z/ a3 S; \double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
7 S& b  T5 ~" l/ Z1 JspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
) Q8 u% j; l4 a% x# x: v- i0 YspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
/ }) Y/ |  ?4 E6 {spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
. u3 }) ?# @3 S3 X: U) s开始创建线：
2 `( h  K/ z0 [* B# L/ \CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
6 Z$ @3 y) I% C( GspLine1 = 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);
4 A2 Z. w' t1 _' @' L6 v$ hspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
! F5 F/ Z( P' r: u% t; D" XCATI2DCurve_var spCurve2 (spLine2);
( t! d6 U9 ]4 ?, `7 C# oCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
. m& D1 |, g* RspCurve1->SetStartPoint(spPt_bottom_left);
* G) Z- G2 x! S/ ZspCurve1->SetEndPoint(spPt_bottom_right);
9 m2 A# K9 }6 e7 r6 O, gspCurve2->SetStartPoint(spPt_bottom_right);
0 c2 x/ I- j" ?2 X9 R8 [& ~spCurve2->SetEndPoint(spPt_top_right);
; L/ [  M) ]! E5 A- ~spCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
2 h6 `% ?' U- g6 y" nspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
* i4 ?, a: P9 I- x  aspSketch->CloseEdition();
+ @  d8 q/ t. G9 |4 [9 U
0 M6 U  ~* W$ M, Z4 x

非常棒，有没有接口之间的关系导图呀
