在上一节的基础上，开始创建草图。首先创建草图工厂：
) P# y( Q, P( n% n( r* O7 I7 ECATI2DWFFactory_var sketch2DFactory(spSketch);
) z& U5 A5 ]2 F* f, R# X下面创建点：
; E7 w3 j: h$ q% _* u3 N; VCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
6 V6 R, x9 O0 V" Zdouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
: U. y8 N; f) r. J. P' x! \double pt_top_right[2]    = {50., 50.};
( L& B8 q2 O" Hdouble pt_top_left[2]     = {10., 50.};
/ z0 ]" A) Y+ U* EspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
( D$ v! J) c( x2 LspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
# t+ n7 T. t: N0 t1 X开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
+ U3 W( h( q, }" b6 nspLine1 = 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);
- w1 E: o! R, z! ?spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
# q" [! u* {+ kCATI2DCurve_var spCurve1 (spLine1);
% r, I7 M7 }! M4 i" z' l5 nCATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
" U3 a; q1 p3 _( F! D! KspCurve1->SetStartPoint(spPt_bottom_left);
1 J' Z" |: G* K9 UspCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
! I) \$ r) q+ @# v( u5 |9 N. mspCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
2 ]8 T) @5 Q8 G3 `! l% MspCurve3->SetEndPoint(spPt_top_left);
* O" G$ G7 F! d0 T' ]; L' QspCurve4->SetStartPoint(spPt_top_left);
- o( ]$ D9 K0 P5 p9 ^6 RspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
9 X$ G  B( C8 r( y# L& espSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
