What meaning it

; error: bad argument type: lentityp nil

lentityp nil = last entity type nil .......... >>>is it true or ???

 

Adesu,

this means that you passed an invalid value to a function that expects an ename - in this case you passed a variable with a nil value.
Try this:

(entget nil)
; error: bad argument type: lentityp nil

(entget 1)
; error: bad argument type: lentityp 1

entget "ADESU")
; error: bad argument type: lentityp "ADESU"

etc...

If you need to - you can check that you have the correct variable type with (= (type var) 'ENAME) before allowing your code to continue.

Hi petersciganek ,thanks a lot

ename - in this case you passed a variable with a nil value.

with (= (type var) 'ENAME) before allowing your code to continue.
