以画一个正方形为例,然后生成面域:
1 G: h" X2 W6 G8 N. g(command "line" "0,0" "0,100" ""
0 G7 u% o, X% s, d(setq l1 (entlast))
% j5 e" L, O# i+ X* ^# @$ L# ^(command "line" "0,100" "100,100" "")) X1 H2 u9 x# i
(setq l2 (entlast))
5 p* c. {1 h1 ^7 ^. p6 s(command "line" "100,100" "100,0" "")

(command "line" "100,0" "0,0" "")
