    i want to find arc entity in lwpolyline without exploding it.
    Using VisualLisp i can't get vertices in lwpolyline through entnext.
    u can suggest for VBA also.

    Arc in pline are "bulge factors".

    pl1 is ename of LWpline.

    (setq enlst (entget pl1))
    (foreach n enlst
    (if (= (car n) 10)
    (setq ptlist (cons (cdr n) ptlist)
    )
    (if (= (car n) 42)
    (setq bglist (cons (cdr n) bglist) ;list of points in polyline.
    )
    ) ;end if
    ) ;end if
    )

    ptlist is list of vertices and bglist is associated list of bulges.
