    Hi all

    I need to extract all the coordinates of a lwpolyline, do some recalucation of them and then update the lwpolyline with new coordinates of all points. Does anyone have the solution for this?

    Yes.
    Something like this:

    (defun mod-poly-coords (/ pline coords newcoords)
    (setq pline (vlax-ename->vla-object (car (entsel)))
    coords (vlax-get pline 'coordinates)
    )
    ;do what you need to with the coords, such as:
    (setq newcoords (mapcar '(lambda (x) (+ 10 x)) coords))
    (vlax-put pline 'coordinates newcoords)
    )

    HTH,
    Jeff

    recalucation of them and then update the lwpolyline with new coordinates
    of all points. Does anyone have the solution for this?
