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);
* [$ B2 s" J  P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.};
0 d& e5 _. O# X0 _1 o$ }' odouble pt_bottom_right[2] = {50., 10.};
( C3 r4 b; r+ h0 cdouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
( u" J- [! @8 f' J5 e% k, bspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
9 y3 ~7 E  v" J6 _% |9 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;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
& z2 K6 I: j( ^* ]2 X2 F) espLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
spLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
" \/ }  [+ w& I" o1 T7 C  L/ Y1 EspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
6 b  C* p: Y; M$ z. jCATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
4 S8 n: ?& u( M, {9 Z' T, WCATI2DCurve_var spCurve3 (spLine3);
% ?( q: Y4 `9 y8 A: O$ T5 ICATI2DCurve_var spCurve4 (spLine4);

6 u4 y+ y7 @" y* o) [spCurve4->SetStartPoint(spPt_top_left);
spCurve4->SetEndPoint(spPt_bottom_left);
; K% {" P5 M# U9 v/ g然后退出草图：

非常棒，有没有接口之间的关系导图呀
