An example for you in lisp it uses the left right up down to draw a pline

 

eg R100 U100 L100 C draws a 100 box

(defun C:ahpliner ( / pt ans)

(command "_pline")

     ((= "C"(strcase (substr ans 1 1)))(command "close"))
) ;cond

tks BIGAL.

but it's wrong i can draw pline by .net very simple

i mean make a pline and pline's property show is "no selection"

:shock:

It is just a bug when you have something selected and you open the properties palette and it says "no selection". You cannot make a pline's property show "no selection".
