以画一个正方形为例，然后生成面域：
$ T- o1 l0 _7 f(command "line" "0,0" "0,100" "" 1 R4 Z2 y4 c1 x7 i, J: r! A
(setq l1 (entlast))6 G! V5 A" G6 a7 t7 V9 H
(command "line" "0,100" "100,100" "")5 Z3 L* t5 \7 H# _( i* J6 h9 v- m
(setq l2 (entlast))
* J% S1 T- U6 g& T9 ^(command "line" "100,100" "100,0" ""): J( N* i- }# `/ X* |- U% Y" s
(setq l3 (entlast))5 F6 l' H( P& D/ q1 P
(command "line" "100,0" "0,0" "")% k- ~2 K6 i* L3 {& G
(setq l4 (entlast))
1 X; F" r E9 [8 P5 W+ U% k9 N% |, W(command "region" l1 l2 l3 l4 "")
6 X( M; J7 F+ {% D3 f(setq en (entlast))
5 t, Z' c! A; D4 J+ q! B(entget en)+ W3 Z+ c! f4 s* T% F) u
下面是执行完上面代码后得到的REGION对象的DXF组码，其属性都可以看到了
