求助：优化程序-让程序运行起来更快输出
下面程序为面积合并计算并输出结果的程序，程序可以正常运行并计算结果，但计算数量多的图形面积时运算比较慢，哪位大师能帮忙优化下就更好了；;;; 功能: 计算多个选择对象的总面积

(setvar "cmdecho" oldcmdecho)
(setq *error* olderr)

restore undox

感谢大佬，程序优化后比原来运行快多了 使用command函数计算，慢是正常的。但用command写代码，稍微容易一点。vlax函数运行是快一些，但有些命令转为用vla或vlax稍微比较麻烦。 qazxswk 发表于 2022-7-4 17:44
