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);
/ A+ w8 w+ `, a, D+ a3 A, Y2 D下面创建点：
& e0 |! w- [" S: O; nCATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
3 O6 N( g3 D) \7 ^( W, qdouble pt_bottom_left[2]  = {10., 10.};
double pt_bottom_right[2] = {50., 10.};
double pt_top_right[2]    = {50., 50.};
double pt_top_left[2]     = {10., 50.};
# A0 i, C# Z" Z) N' [& dspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);
5 D: x7 Y5 O2 ]spPt_top_right    = sketch2DFactory->CreatePoint(pt_top_right);
+ ?& x* {1 _  n; O! q2 W! EspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
开始创建线：
CATI2DLine_var spLine1, spLine2, spLine3, spLine4;
5 K; X' r( T7 v: w* ^9 P) p4 XspLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);
spLine2 = sketch2DFactory->CreateLine(pt_bottom_right,pt_top_right);
& I- U5 N* \0 a2 s# l/ k# C4 L: R! NspLine3 = sketch2DFactory->CreateLine(pt_top_right,pt_top_left);
spLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
将线连接起来：
, O) m% O6 R2 [5 [CATI2DCurve_var spCurve1 (spLine1);
CATI2DCurve_var spCurve2 (spLine2);
. e5 N$ X! f; d& V! \7 P* g, v  eCATI2DCurve_var spCurve3 (spLine3);
& F  ^9 j" B5 Z+ c* aCATI2DCurve_var spCurve4 (spLine4);
spCurve1->SetStartPoint(spPt_bottom_left);
spCurve1->SetEndPoint(spPt_bottom_right);
spCurve2->SetStartPoint(spPt_bottom_right);
7 a3 w% u1 m# k, P8 KspCurve2->SetEndPoint(spPt_top_right);
: k6 i! X8 B  W% ^% i7 RspCurve3->SetStartPoint(spPt_top_right);
spCurve3->SetEndPoint(spPt_top_left);
  E$ ^# Y9 y+ |; v2 E* o) g+ XspCurve4->SetStartPoint(spPt_top_left);
, \% _0 O# q$ wspCurve4->SetEndPoint(spPt_bottom_left);
然后退出草图：
spSketch->CloseEdition();
8 y( `% c( n. q

; \/ W$ O3 i. @4 {/ ?* K

非常棒，有没有接口之间的关系导图呀
