Fillet multi lines

[muhamed_ragab92]

Please i want lisp or code source to fillet some line with fixed radius ? Anyone can tell me about that

[john.uhden]

I had thought that the FILLET command required (ename pt) as in (entsel) but in recent testing in 2002, I found it required just the points.

Good work, Kent, as usual.

for me just work for one polyline.

what I did bad? (attached file)

;;; Helper function to get the point from pt1 perp to entity picked at point pt2
(defun GetPerpPoint (pt1 pt2 /)
  (setvar "LASTPOINT" pt1)
  (osnap pt2 "_perp")
) ;_ end of defun

;;; Helper function to get the distance from pt1 perp to entity picked at point pt2
(defun GetPerpDist (pt1 pt2 /)
  (distance pt1 (GetPerpPoint pt1 pt2))
) ;_ end of defun

(setq MFillet:Inc "No") ;Remember increment fillet

;;; Fillet multiple lines by selecting with fences
(defun c:MFillet_v2 (/ ss1 ss2 n m en1 en2 pt1 pt2 ptlast rad rad1 cmd)
  (setq cmd (getvar "CMDECHO")) ;Get value of CMDECHO
  (setvar "CMDECHO" 0) ;Don't show prompts on command line
  (command "_.UNDO" "_BEgin")

If you want something else ask in other post ?

[jtm2020hyo]

I need to work with both

their lisp have more options but just work with lines and allow me to do 2 lines with 4 points no consecutive

your lisp works with lines and polylines but just allow me to do 2 consecutive lines with 3 points consecutive and is harder and I found some errors.

Post true examples in dwg that did not work.
