在上一节的基础上，开始创建草图。首先创建草图工厂：
3 j0 f- s, w9 hCATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
! o' ]7 x* k0 m* K* s' H2 k9 d, Udouble pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
/ b$ X4 m6 ]) ^) \; NspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
$ r$ P% @  B1 ispPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
: m  E) x: h# X* w开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
" Q& B: D9 k) Z; X( ~' J$ x5 BspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
' S, K3 L- |) NspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
7 O. e# i; i0 m" N, u' e4 F, W2 _将线连接起来：
$ F  @2 r& @+ H/ Q. MCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
! y& F8 W# @" |3 o) z& g% |- V" ECATI2DCurve_var spCurve3 (spLine3);
6 o* K; Z* D0 KCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
7 ]3 A' F4 j6 A- O! wspCurve1->SetEndPoint(spPt_bottom_right);
( T8 E3 w) L* E' I- n6 f# y" PspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
/ S8 s& \2 h: L$ M. bspCurve3->SetStartPoint(spPt_top_right);
$ {: P$ L  O, ?spCurve3->SetEndPoint(spPt_top_left);
# e. V9 m+ t% dspCurve4->SetStartPoint(spPt_top_left);
, G; Y( o2 D/ L9 z7 yspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
& X1 n1 _& U' g; Y8 K$ B. ~
, H9 v5 F7 m' y: H, V1 A

非常棒，有没有接口之间的关系导图呀
