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：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
* f- o8 {: {9 S  Bdouble pt_bottom_left[2]  = {10., 10.};
4 Z% R* Y% \: C: Xdouble pt_bottom_right[2] = {50., 10.};
8 A9 K' _& k( F0 Mdouble pt_top_right[2]    = {50., 50.};
% t3 F$ T' Q9 V1 e; f  U2 [double pt_top_left[2]     = {10., 50.};
! q' x4 _, q, `spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
6 M$ h6 r' a$ u2 g  U; @- }% `$ bspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
; x$ o4 q: E" ?: M2 q开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
" P1 B; Z! R. [, A) \) DspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
$ \" b9 G! n3 Q. e. XspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
) W, C4 Z+ y  G5 H; y将线连接起来：
+ r) ~# [: C3 L6 Q3 o8 Z6 }* f! [CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
# U; ]$ M5 ?; f* u, }! f$ vCATI2DCurve_var spCurve3 (spLine3);
0 e, c% g: R) H6 U$ H; ICATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);

0 v6 Q. x' H0 [4 L: R( H% `" h" AspCurve2->SetEndPoint(spPt_top_right);

- K( A/ I4 B6 W+ IspCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
! }( Z2 T! Q" h+ lspCurve4->SetEndPoint(spPt_bottom_left);
$ ^3 D9 A2 ^$ {) X: N/ g然后退出草图：
spSketch->CloseEdition();

1 g& H( N- L4 w9 i+ I. r
$ b4 f& t5 L- x7 h  I* |- T

非常棒，有没有接口之间的关系导图呀
