Another for fun: (defun c:foo (/ a b el l s w) ;; RJP » 2025-07-23 ;; Creates separate polyline segments preserving widths etc.. (cond ((setq s (ssget '((0 .

"AcDbPolyline") (reverse el))) '((90 . 2)))) (setq b (vl-remove-if-not '(lambda (x) (member (car x) '(10 40 41 42))) el)) (while (cddddr b) (setq l (list (car b) (cadr b) (caddr b) (cadddr b))) (setq w ;; Set global width if start and end are 'equal' (if (equal (cdadr b) (cdaddr b) 1e-4) (list (cons 43 (cdadr b))) ) ) (setq b (cddddr b)) (entmakex (append a (append l w (list (car b) (cadr b) (caddr b) (cadddr b))))) ) (entdel e) ) ) ) (princ) )

Even with AutoCAD probably still pretty fast for fence, but a LISP would help. I tried several things and I can't get AutoCAD 2026 to double extend as per @BIGAL's example.

Yet another...

Going to have to click a little then. or use fence like BIGAL shows.
