" 命令用法:" " MKPAT -- 初始化程序环境;"
" PNEW -- 清除屏幕,开始新图案设计;"
" PIMP -- 装入已有的图案,供参考修改,程序提示输入图案名及比例因子。"
" PSAVE -- 生成、测试及存储当前设计图案。程序提示输入图案名、描述字串及"
"测试角度,生成的图案定义存入<图案名.PAT>文件中"
" PHELP -- 程序说明,帮助;"
" BYE -- 退出MKPAT,恢复ACAD环境。" "" " 程序说明:"
" MKPAT程序是用AutoLISP语言编写的HATCH命令图案PAT文件自动生成实用工"
"具,使用过HATCH命令的用户都知道,图案定义文件(PAT)是纯文本文件,户允许用"
"自己编写扩充用户的图案库,然而编写图案定义文件并不是一件轻松的事,而有些"
"定义用手工根本无法计算。有了MKPAT,你就可以轻轻松松地制作出任何复杂的"
"图案来,只要你想得到,MKPAT就做得到。"
" MKPAT对用于制作图案的矢量线段有一些简单的限制(其实这是AutoCAD的限"
"制),用户必须严格遵守这些为数不多的限制条件,才能制作出满足AutoCAD标准的"
"图案定义文件来。"
" 首先:并不是所有的AutoCAD实体类型都适合制作PAT图案,能够用于图案制作"
"的实体类型只有点(POINT)、线(LINE)及多义线(POLYLINE),拟合的多义线及其线宽"
"的变化并不会反映在制作的图案中,程序仅使用多义线的顶点坐标;第二,也是最"
"重要的限制是任何矢量线段的斜率或斜率的倒数必须为整数,也就是说,线段的dx"
"与dy之较大者与较小者之比为整数。只有满足这两个条件的实体,才能用于图案"
"制作。"
" MKPAT程序只有一个文件MKPAT.LSP,可以在任何图形设计文件中装入该程序"
"并运行之,MKPAT会保护现场并在你退出MKPAT时恢复,PAT图案可以随时制作随"
"时使用,但是为了保险起见,建议你打开一个新图形文件来制作PAT图案,以免误"
"操作损坏你的图形文件,同时也可提高程序运行速度。" ""
" 图案制作步骤:"
" 1.用MKPAT命令初始化程序环境后,屏幕左边大半部份为1*1图形单位的矢量"
"绘图区,右半部为图案测试区及版权信息。"
" 2.在绘图区用点、线及多义线绘制构成图案的基本单元,注意所绘实体应满"
"足程序说明中提到的要求。"
" 3.用PSAVE命令生成、测试所制作的图案,如有不合要求的线段或测试不满"
"意,修改基本图素后重复此命令，直到满意为止。将生成的PAT文件放入AutoCAD"
"的支持目录或加入到ACAD.PAT文件中就可以使用了。"
" 4.用PNEW命令清除当前设计,开始新的图案设计工作；用PIMP命令可以装入"
"以前的设计供修改或以已有的图案为基础设计新的图案。"
" 5.设计制作完成后,用BYE命令恢复AutoCAD环境。" ""
" 使用技巧:"
" -- 程序初始化后,网格和捕捉模式均为打开状态,因此在绘图区绘制矢量时应捕"
"捉在网格点上。"
" -- 在用线段模拟曲线时,在一个方向前进一个网格距,而在另一个方向上则可前"
"进任意网格距,重复操作可以画出很好的模拟曲线,并且所画线段完全可以通过有"
"效性检查。"
" -- 如出现不能通过有效性检查的矢量线段,建议用鼠标通过夹点编辑修改之,修"
"改后直接按<Enter>键或鼠标右键可重复PSAVE命令,以提高制作效率。"
" -- 可以用MKPAT制作复杂的图案要素,而图案中比较规则的定义矢量用手工编辑"
"PAT文件添加,可以有效地减少PAT文件的定义矢量数目。")
