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：
! [* `5 Y4 u" v( H: G, hCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
3 ?4 e8 @: G% h0 _/ O; F; X8 X, xdouble pt_bottom_right[2] = {50., 10.};
" N+ {8 r$ p# v  Jdouble pt_top_right[2]    = {50., 50.};
# X) s1 m- c* G9 h6 r8 `' ]double pt_top_left[2]     = {10., 50.};
4 D' i4 ]7 \0 P3 Q1 T3 L: c5 TspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
) y9 w0 i1 }6 V5 k8 ~开始创建线：
6 a/ \. c" G  w7 I% uCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
7 S9 x' e8 _, ~* W! j! y: bspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
4 c* s3 D0 ?/ v7 PspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
" u: W6 Z3 S# D# Q0 b1 ~9 vCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
& _* n( o4 \) f- ?  a& B2 t- pCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
/ f5 `! e8 O; a% E8 hspCurve1->SetEndPoint(spPt_bottom_right);
9 h& ^0 o! V8 i5 r6 }spCurve2->SetStartPoint(spPt_bottom_right);
5 \  G2 k# E/ AspCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
+ ~) s8 }" l, ^! d& t. PspCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
3 p& z3 Q. D: I5 G! VspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
% e4 d: p' |; Q2 s
7 e6 D6 U6 d9 t- |9 {7 @

非常棒，有没有接口之间的关系导图呀
