在上一节的基础上，开始创建草图。首先创建草图工厂：
0 k/ P; M* v" z) ECATI2DWFFactory_var sketch2DFactory(spSketch);
下面创建点：
, c6 H# f# X8 z1 |1 hCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
4 ]2 O, q: `) i4 N4 L! R5 {( B( M* {double pt_bottom_right[2] = {50., 10.};
: @6 a" d  F3 I9 cdouble pt_top_right[2]    = {50., 50.};
9 v2 m" e% d  e2 W; ]' e! _double pt_top_left[2]     = {10., 50.};
3 n+ I* O9 i' X+ a) m/ NspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
6 d# [7 w, l5 E9 h/ d1 u( LspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
1 C7 l3 x" r! p- S% T9 [spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
+ u# l' E8 M4 ^1 `8 G- A  n) EspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
6 }% [$ @3 Z( \( }1 Z, v4 \! r) QCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
, i; @, h( {3 l2 l- tspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
# E2 p- B+ E: w# DspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
) K3 Z2 O5 x1 V2 ?4 x+ V9 H; ospLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
* H( d2 a6 n* f, l8 V# P! o0 Q% M% jspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);
0 }* E. ?9 x! l6 }4 I: GCATI2DCurve_var spCurve2 (spLine2);
" ~! k& R+ A/ ^' v/ lCATI2DCurve_var spCurve3 (spLine3);
CATI2DCurve_var spCurve4 (spLine4);
7 U) j* m0 y! Z& X- mspCurve1->SetStartPoint(spPt_bottom_left);
% q; i, z1 ]& f  `spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
- {. V% `% Z8 i; ^: a. ZspCurve3->SetStartPoint(spPt_top_right);
! i# Y6 q# ~- U/ i5 vspCurve3->SetEndPoint(spPt_top_left);
- W: x7 k/ Z( n* f4 ?$ ^spCurve4->SetStartPoint(spPt_top_left);
" @- ?" u5 w3 n2 `spCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
& K" @( M' }) U% @, C* c4 Q

非常棒，有没有接口之间的关系导图呀
