"I tried creating a code to input the fillet radius at the beginning, referring to the Lisp program you created. However, since it requires input every time, what should I do to make it possible to retain the previously input value in the input field?"
----------------------------------------------------------------
(defun C:FMP ;Fillet Multiple Polylines
(/ plss n radius)
(setq radius (getreal "\Enter fillet radius: "))
(if (null radius)
(progn
(princ "\nError:Fillet radius is not inputted。")
(exit)
)
(if (setq plss (ssget "_:L" '((0 . "LWPOLYLINE"))))
(repeat (setq n (sslength plss))
(command "_.fillet"
"_polyline"
"R"
radius
(ssname plss (setq n (1- n)))
)
)
) ; if
) ; if
(princ)
) ; defun

"It was already resolved with FilletMultiplePolylines.lsp.
Thank you very much."
