在上一节的基础上，开始创建草图。首先创建草图工厂：
9 d9 p) Q( y( e+ LCATI2DWFFactory_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.};
double pt_bottom_right[2] = {50., 10.};
% e# w7 U& ^0 s0 r! mdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
# C9 c  U5 U9 DspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
( X+ p& z& P: hspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
, L. k4 \' \8 _5 C4 f2 P! u* RspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
' ]8 X( k9 j2 z# I; LspLine2 = 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);
3 N- y& H7 E. h  w2 O% q" n  z- _& k将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
. |+ x$ N4 a; X" Z# U. `/ u, aCATI2DCurve_var spCurve3 (spLine3);
7 d; b8 w9 O. g' cCATI2DCurve_var spCurve4 (spLine4);
% v4 R1 E9 V5 n; |4 Y" p, D& XspCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
: U) |5 K7 ~$ D8 P. cspCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
8 k" b7 ^; j! b" P' Q' xspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
8 ~* A; k# Z5 G" ^. @: ~spCurve4->SetStartPoint(spPt_top_left);
* M1 f8 n1 D) @$ \, M# SspCurve4->SetEndPoint(spPt_bottom_left);
8 G/ q" B9 L/ n/ _4 P* t然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
