定义块方法：" y/ Z" T5 m+ P
Set blocksobj=ThisDrawing.Blocks.Add(基点, 块名)5 o$ d% a+ r0 e6 S/ A8 o# [
把选择集加入块中的方法：
3 X/ M1 P* H/ r2 RThisDrawing.CopyObjects(选择集,块)
1 {% Y/ K# I( w+ d插入块方法：
. [9 B7 J7 Z- X5 @4 DThisDrawing.ModelSpace.InsertBlock(插入点,块名, X轴比例,Y轴比例,Z轴比例, 旋转角度) 1 G3 z% g3 e8 B7 p
画块属性方法：
8 C3 R1 [9 C& d E1 @( LThisDrawing.ModelSpace.AddAttribute(文字高度,模式,提示字符, 插入点, 显示字符,默认值)1 Y% c5 X6 s$ b6 F3 ^
一共有五种模式，在输入时会有提示，其中最常用的是“acAttributeModeNormal”普通模式. L" k1 ~* H7 W$ F2 I
编程思路：
0 x& i, u1 v! B X1．定义一个空块
" y: C# n: Y! p I1 s2．在块中画一段弧（球服衣领）0 P& A- W6 g" c" U( B5 `( ^
3．画多段线，镜像画出球衣0 T5 k! @& u& y0 J, u, ~
4．画块属性，由于块属性默认的对齐方式是左对齐，而球员号码应该居中，所以必须把块的对齐属性改为居中。但是当这个属性更改时块属性对齐点会自动归零，所以不得不再次更改对齐点属性! c; @4 v- X" \4 B) S8 g( n+ Q9 E
5．把多段线和属性复制到块中* t x E" @" k- v# C$ S& F
6．提示用户点选球员位置和姓名 }+ d/ A5 G+ a& M b3 q( l
7．插入块，修改球衣号码属性、球员姓名属性
