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);
下面创建点：
CATI2DPoint_var spPt_bottom_left, spPt_bottom_right, spPt_top_right, spPt_top_left;
1 n' s' a# b2 ]" M8 ], mdouble pt_bottom_left[2]  = {10., 10.};

% D' _' i* Q& _5 H3 {double pt_top_left[2]     = {10., 50.};
0 [( F' [; B* N# Z1 SspPt_bottom_left  = sketch2DFactory->CreatePoint(pt_bottom_left);
spPt_bottom_right = sketch2DFactory->CreatePoint(pt_bottom_right);

6 h4 I; Z- d8 K- zspPt_top_left     = sketch2DFactory->CreatePoint(pt_top_left);
) t6 m8 c2 h7 T: D" t0 v5 z开始创建线：

spLine1 = sketch2DFactory->CreateLine(pt_bottom_left,pt_bottom_right);

/ r& N8 c0 ?# r7 x$ w; q$ PspLine4 = sketch2DFactory->CreateLine(pt_top_left,pt_bottom_left);
2 c3 ^% W- z* l: u将线连接起来：

非常棒，有没有接口之间的关系导图呀
