Change chamfer results to the current layer?

[BrianTFC]

Hi All

Does any one have a Lisp routine to turn the diagonal line that chamfer creates to the current layer instead of the original layer of the lines? I would appreciate any help.


Thanks
Brian

Is your stated version (2000i) an older LT version? Is it LISP capable?

[BrianTFC]

We use 2000i and 2012

[alanjt]

(defun c:Chamfer2 (/ ent)
  (setq ent (entlast))
  (command "_.chamfer")
  (while (eq (logand 1 (getvar 'CMDACTIVE)) 1) (command PAUSE))
  (if (not (equal ent (setq ent (entlast))))
    (entmod (list (cons 8 (getvar 'CLAYER)) (cons -1 ent)))
  )
  (princ)
)

Thanks that is exactly what i was looking for...

You're welcome.

But when chamfering a Polyline object while Trimmode variable is set to zero, there may be more than one object as the result of CHAMFER.
For this case alanjt's nice code can be edited to:

(defun c:Chamfer2 (/ ent)
 (setq ent (entlast))
 (command "_.chamfer")
 (while (eq (logand 1 (getvar 'CMDACTIVE)) 1) (command PAUSE))
 (while (setq ent (entnext ent))
  (entmod (list (cons 8 (getvar 'CLAYER)) (cons -1 ent)))
 )
 (princ)
)

Be careful when 'entlast' is an Attribute Block or Polyline.

Be careful when 'entlast' is an Attribute Block or Polyline.

I checked Polyline and it doesn't cause any error on VERTEX and SEQUEND objects, but changes ATTRIB objects. So the code can be edited to this one:

(defun c:Chamfer2 (/ ent)
 (setq ent (entlast))
 (command "_.chamfer")
 (while (eq (logand 1 (getvar 'CMDACTIVE)) 1) (command PAUSE))
 (while (setq ent (entnext ent))
  (or
   (member (cdr (assoc 0 (entget ent))) '("ATTRIB" "VERTEX" "SEQUEND"))
   (entmod (list (cons 8 (getvar 'CLAYER)) (cons -1 ent)))
  ) 
 )
 (princ)
)
