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);
7 t3 N- I. k6 m6 U+ M2 F1 U" p' P下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
" Q4 D5 j/ m" {* E$ @. f7 _double pt_bottom_left[2]  = {10., 10.};
# v* u2 j% W3 v1 Pdouble pt_bottom_right[2] = {50., 10.};
* g7 @3 Z  Q$ F3 ~double pt_top_right[2]    = {50., 50.};
6 Z: O0 O6 t! F- s. n; `double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
0 A7 p$ `& E( f& TspPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
% m1 l. E8 T8 d: C5 j' u1 s0 m/ p* OspLine1 = 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);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
; R6 d; S/ J7 f9 ]8 jCATI2DCurve_var spCurve1 (spLine1);
: c( ]; |. j9 D8 `" D5 e4 g) q( g. TCATI2DCurve_var spCurve2 (spLine2);
, x8 i, d$ T; r2 m1 A! S3 vCATI2DCurve_var spCurve3 (spLine3);
& C/ A7 c8 S. a% b$ CCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
: @9 y6 r: }$ ZspCurve2->SetEndPoint(spPt_top_right);
spCurve3->SetStartPoint(spPt_top_right);
4 S+ y/ K4 _0 o9 B0 K) ]6 T5 y+ KspCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
& A1 k; r' D, @+ C然后退出草图：
& Z5 p7 t% [  ^: W" d1 m( |0 YspSketch->CloseEdition();
% o; J- P- w/ Y, }' H. M
4 z& ~) ]9 |9 X& s& S, \
: H  `; n" X, q9 I. \

非常棒，有没有接口之间的关系导图呀
