求一个多图元类型自动标注程序！
本帖最后由 半听可乐 于 2012-12-10 13:01 编辑本人尝试了一些自动标注程序，包括一些广为熟知的商用软件里的自动标注，发现大多只对单一对象就行标注，能不能实现对指定的多种类型的图元进行标注呢？因为有些图元不光要标间距，还要标与周围墙、柱子的距离，这时就得手工调整了，如果工程较大那真是苦不堪言，一次就罢了，改图时那种痛~~~不说了，各位高手请看插图和附件

帮你做了一个，严重建议你将喷头的块炸开成圆。

院长动作真快！佩服佩服！可以标柱中、墙中吗？ 半听可乐 发表于 2012-9-5 13:10 static/image/common/back.gif

便于工人下料啊，尺寸看起来也简单 你说的2和4不是cad认识的类型，要做也得做一些处理 本帖最后由 半听可乐 于 2012-9-5 16:54 编辑

就是想要高手的处理，我的思路是
①判断墙线间距，如果间距在500以内，则在两墙线之间画中心线，个人提供中心线参考程序如下
②把画出的中心线当作自动标注的捕捉点之一，自动标注
③标注完成后删除中心线
也许没那么复杂（我想如果能自动计算出中心点，而不需要画线）
