全部用纯lisp,没有vlisp,因为不会。
cad2004,2005测试通过,其它版本未测试。
未考虑z坐标及ucs
arc(pl-arc),circle由pl逼近,以实际打印长度0.2mm为控制长度,
如果弧线很长,运行速度会很慢。
可转换实体:LINE,ARC,CIRCLE,LWPOLYLINE,TEXT,INSERT,RAY,XLINE,SOLID
其中pl可为不定宽度arc及line。
属性块中属性与块作为一个整体。
提供源码,请高手指点。

;transform plan to sys
;entities can be transformed: LINE,ARC,CIRCLE,LWPOLYLINE,TEXT,INSERT,RAY,XLINE,SOLID
