Req : draw polyline with instant changeable offset side

[Abdulellah]

as shown in bottom image , there is an  yellow poly line have multi side  offset of red lines boundary , this mission can be done with offsetsegments  lisp , but , you need to draw polyline exactly on boundary as duplicate line then you can run lisp to get your offset with your desired offset side .

 

i wonder if it is possible to write lisp to do this task instantly when draw polyline (add new  sub command   offset value and offset side ) when run  main polyline command
