在上一节的基础上，开始创建草图。首先创建草图工厂：
+ N0 q' m. i, }3 n, }7 a# ]CATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
& E% n. E/ _8 u) u# hCATI2DPoint_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.};
double pt_top_left[2]     = {10., 50.};
0 e: k* @5 V  w0 Y" XspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
. z" L! L, e2 X4 _spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
4 O, c. m6 o' P; B( k开始创建线：
* D4 I$ [( `1 Z, BCATI2DLine_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);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
+ B0 U1 [8 f$ u! N' N5 N5 v7 iCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
8 S; F! w0 B( T1 ?/ u! u( bCATI2DCurve_var spCurve3 (spLine3);
: M& n. K9 S% z5 w4 @0 x1 rCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
* N6 t! z, z9 E1 s5 ispCurve1->SetEndPoint(spPt_bottom_right);
" `! o0 O, \1 K4 l: o- P, cspCurve2->SetStartPoint(spPt_bottom_right);
' x  Q5 G6 [& g7 R( G( NspCurve2->SetEndPoint(spPt_top_right);
' M( V; |3 Z3 W) y% A, E4 T4 c0 m: a6 pspCurve3->SetStartPoint(spPt_top_right);
" I9 @0 z1 w" N+ w7 @. K2 Z- z: s3 UspCurve3->SetEndPoint(spPt_top_left);
7 D2 J3 z; s  p6 N( i) B4 pspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
