怎样知道ucs名已使用

54256

保存当前ucs时
(command "ucs" "s" "1234")
若“1234”已经被使用，需要增加一个“y”
(if ******
        (command "ucs" "s" "1234" “y”)
        (command "ucs" "s" "1234")
)
请问一下*****部分该怎么写

1. (= (getvar "ucsname") "1234")

(= (getvar "ucsname") "1234")

这个没用吧，若目前的ucs不是“1234”,想存为“1234”就不管用

方法1：(not (vl-catch-all-error-p (vl-catch-all-apply 'vla-item (list (vla-get-usercoordinatesystems (vla-get-activedocument (vlax-get-acad-object))) "1234"))))
方法2不需要判断：(vl-cmdf "ucs" "save" "1234") (if (= (getvar "cmdactive") 1) (vl-cmdf "y"))
