caoyin大哥，一个标注尺寸与样式中定义的比较问题
www.dimcax.com

命令: (entget (car (entsel)) '("acad"))
选择对象: ((-1 . <图元名: 7ef4fe08>) (0 . "dimension") (330 . <图元名:
7ef4fd08>) (5 . "41") (100 . "acdbentity") (67 . 0) (410 . "model") (8 . "0")
(100 . "acdbdimension") (2 . "*d3") (10 324.289 149.057 0.0) (11 246.493
150.932 0.0) (12 0.0 0.0 0.0) (70 . 32) (1 . "") (71 . 5) (72 . 1) (41 . 1.0)

"acdbrotateddimension") (-3 ("acad" (1000 . "dstyle") (1002 . "{") (1070 . 343)
(1005 . "3b") (1070 . 173) (1070 . 1) (1002 . "}"))))
caoyin大哥，上面是我在特征中改了一个尺寸的第一个箭头变成我的定义的一个箭头来的，，我也看出来啦
(1070 . 343) (1005 . "3b")中"3b"是代表了我这个箭头的来的，caoyin大哥，我就是想知道一下，反过来怎么样知道"3b"就是代表我的这个箭头，还有别的用户箭头又是多少呢，这个在那查的呀，，如果是cad自带的箭头，我就会知道的呢，帮帮我呀"。caoyin大哥

caoyin大哥，我把定义的箭头块插了两三次，每次看到的句柄都不相同，其实我只是想知道我打开别人的dwg图时，用上面的代码，查出-3组码内容后，我想知道343或344组码的内容到底代表着是哪一个用户定义的箭头块，然后我又在命令行中输入dimblk1或dimblk2或dimblk后，我要输入这个定义箭头块的名称字符串，回车就可以改变，这就是我想要达到的目的 caoyin大哥再帮帮我，谢谢
