刚看到一个朋友讨论HATCH，以前的程序对于HATCH我都是用命令去做，有没有ENTMAKE生成的方法？我试了几次，都没成。

哇，这么长，都是必要的吗？能给讲讲每个组码的值的含义吗？谢谢！！！

边界路径数据
每个图案填充对象的边界由包含一条或多条线段的路径（或环）定义。路径线段数据取决于构成路径的图元类型。每条路径线段由它自己的组码集定义。关于此表中使用的缩写和格式方面的信息，请参见“本参考的格式惯例”。图案填充边界路径数据组码

组码  说明

92  边界路径类型标志（按位编码）：
0 = 默认；1 = 外部；2 = 多段线
4 = 导出；8 = 文本框；16 = 最外层

不确定
多段线边界类型数据（仅当边界 = 多段线时）。参见下面的多段线边界数据表

93  该边界路径中的边数（仅当边界不是多段线时）

72  边类型（仅当边界不是多段线时）：

下面是关于HATCH的各种代码

1、DH-2line places hatch between two parallel lines
2、 DH3 uses points picked for three Corners, long side then width
3、 Hatch - Unlimited points
4、Hatch - Creates separate hatch with several objects
5、Hatch- Quick pick hatch command
6、Hatch - Matches the properties of existing hatches (sets only)
7、Hatch - Matches existing hatch and allows user to pick new object
8、Hatch - 2-point hatch
9、Hatch - 2-point circular
10、 Hatch - Pick internal point

把它做成函数呢！这样算方便了！

以前写的一个函数，绘制Hatch，ea:init的意义搜索相关帖子，这个函数是根据图中已有的填充生成填充图例，其中用到了Vla方法生成填充
;;参数：
;;space 图例间距
;;pl 表 hatch - patternname 、color (truecolor)
;; Gradienthatch - gradientname 、 color1 、color2 (渐变填充)
;;pt 基点
