在上一节的基础上，开始创建草图。首先创建草图工厂：
% k& j( e7 |/ U! ]2 i9 [" q- ?- zCATI2DWFFactory_var sketch2DFactory(spSketch);
* T) O8 Z: h# s. E下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
- m8 d- }6 h6 B) ?( jdouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
# r: b# ?: N4 M# Bdouble pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
. G2 o: a# l9 \, k5 Y9 H4 ispPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
4 ]% S& y; {1 ^+ z( \# R; l: ZspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
/ P, A0 N: c5 ?3 D开始创建线：
CATI2DLine_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);
% V9 @1 ]2 z+ T- Z7 hspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
- L* M, _: R# h) @将线连接起来：
! v# p3 n* \( l9 M4 ^$ o& p4 nCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
CATI2DCurve_var spCurve3 (spLine3);
9 Z1 h$ a' T+ t% v6 ^CATI2DCurve_var spCurve4 (spLine4);
$ g9 K3 {! N  I. Z8 ^9 `% a) wspCurve1->SetStartPoint(spPt_bottom_left);
- }! [1 h/ v8 C/ J- CspCurve1->SetEndPoint(spPt_bottom_right);
# D; ]" Q  [) Y2 a* bspCurve2->SetStartPoint(spPt_bottom_right);

spCurve3->SetEndPoint(spPt_top_left);
: A, \+ e# _. H4 sspCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
: l4 W- w+ A9 w  }spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
