在上一节的基础上，开始创建草图。首先创建草图工厂：
  H/ ^. |$ H9 v! C. [8 ]CATI2DWFFactory_var sketch2DFactory(spSketch);
' S. k/ s, @+ {4 v下面创建点：
. Y) n2 M6 s- a+ i" C& [CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
double pt_bottom_left[2]  = {10., 10.};
( y, O5 n. G5 _) S, @. K1 Tdouble pt_bottom_right[2] = {50., 10.};
2 ~2 ?+ f' g( Z. ]4 ^" V# Idouble pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
spPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
/ c3 x( u& z. r6 ^2 u  }: u& L5 N' JspPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
9 d& `- h. G# I0 i! A4 {spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
spPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
0 P0 r3 d8 l0 E" B( D开始创建线：
, x- M; X  w4 v' U4 Y2 m, sCATI2DLine_var spLine1, spLine2, spLine3, spLine4;
spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
/ \) S+ j) q& wspLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
  y6 S4 r  D3 D: l# A& tspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
' a6 `  ~8 C* G/ m5 _+ j9 U6 d. P0 N; v3 mspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
7 s( G/ f  p$ ?1 S7 _将线连接起来：
CATI2DCurve_var spCurve1 (spLine1);

spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
spCurve2->SetEndPoint(spPt_top_right);
2 k6 W$ |6 ^/ k- [  P7 UspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
spCurve4->SetStartPoint(spPt_top_left);
( e5 m9 C% o7 r: H8 k1 `  AspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();

非常棒，有没有接口之间的关系导图呀
