Offset LISP Routine just needs small update. Thanks!

[tmelancon]

Just came across this neat little LISP routine. Works perfect for me and my guys because we insulated pipe and this eliminates having to click click click click to constantly offset lines both ways.

 

(defun C:OFF2  (/ pickEnt pickObj offDist)
(vl-load-com)
(setvar "ErrNo" 0)
(while (and (not (setq pickEnt (entsel))) (/= 52 (getvar "ErrNo"))))
(cond ((and pickEnt
            (setq pickObj (vlax-EName->vla-Object (car pickEnt)))
            (progn (initget 6)
                   (setq offDist (getdist "\nSpecify offset distance: "))))
       (vla-Offset pickObj offDist)
       (vla-Offset pickObj (- offDist))
       (I:PutCL pickObj)))
(princ))

(defun I:PutCL  (myObj / linetypes ltName)
(setq linetypes (vla-Get-Linetypes (vla-Get-Document myObj))
      ltName    "Center")
(cond ((vl-catch-all-error-p
        (vl-catch-all-apply 'vla-Item (list linetypes ltName)))
       (vla-Load linetypes
                 ltName
                 (cond ((= (getvar "Measurement") 0) "Acad.lin")
                       ("AcadISO.lin")))))
(vla-Put-Linetype myObj ltName))

 

Question: Can someone have a look and instead of prompting for offset distance (since we already have a standard set distance ALWAYS) of 0.812 so thats what I would need. Also can someone add a for multiple piece?

 

 

God bless!

hi tmelancon, this quick modify for single click,

can you explain M for other selection? or repeating for the same entity?

(defun C:OFF2 (/ pickEnt pickObj offDist)
 (vl-load-com)
[color="red"] (setq offDist(ureal 6 "" "\nSpecify offset distance: " 0.812))[/color]
 (while (setq pickEnt (entsel))
   (cond ((and pickEnt (setq pickObj (vlax-EName->vla-Object (car pickEnt))) offDist)
   (vla-Offset pickObj offDist)
   (vla-Offset pickObj (- offDist))
   (I:PutCL pickObj)
   )
  ) ;_ end of cond
   ) ;_ end of while
 (princ)
 ) ;_ end of defun

(defun I:PutCL (myObj / linetypes ltName)
 (setq	linetypes (vla-Get-Linetypes (vla-Get-Document myObj))
ltName	  "Center"
) ;_ end of setq
 (cond	((vl-catch-all-error-p (vl-catch-all-apply 'vla-Item (list linetypes ltName)))
 (vla-Load linetypes
	   ltName
	   (cond ((= (getvar "Measurement") 0) "Acad.lin")
		 ("AcadISO.lin")
		 ) ;_ end of cond
	   ) ;_ end of vla-Load
 )
) ;_ end of cond
 (vla-Put-Linetype myObj ltName)
 ) ;_ end of defun

(setq OffDist...)

Hey sorry, I was busy this morning and didnt quite word it that well. I am looking for the offset multiple to be included somewhere in there to give the user the option of just offsetting a single line then ending the routine, or type for multiple line selections. Hope this helps!

[iconeo]

If you are starting this lisp from a button you can simply add an asterisks before the command as such...

 

*^C^C(if (not c:OFF2)(load"OFF2")) OFF2;

 

This assumes that the lisp is in one of your support directories and is named OFF2.

 

Cheers.

Hmm its prompting for user to hit enter/spacebar to initiate the 0.0812 for the actual distance. I tried adding "" to the back of the dist and its stating too many arguments. I was just trying to add it so it hits enter automatically and just prompts for line selection.. why is it arguing with me

[iconeo]

I would think that:

 

(setq offDist(ureal 6 "" "\nSpecify offset distance: " 0.812))

 

could simply change to...

 

(setq offDist 0.812)

PROPS TO EVERYONE! SUCCESS! Thanks to you all. You guys are awesome! :notworthy:

[tmelancon]

Would it be possible just as we are specifying line type, if we could do the same with layer.. Like put it on a specified layer of choice? The two offset lines?

yes we can modify the code, but you make sure remarking courtesy to the author of original code, credit to his ideas or notify him.

 

this example: i use (getvar "clayer") current layer

For [multiple], key-in M -> then key-in offset distance -> select multuple objects

Edited August 9, 2014 by hanhphuc
*offset* is global variable

[BIGAL]

2 suggestions you can wrap the routine in a While that is keep picking objects the moment you pick nothing, space on screen, it exits 1 pick is ok or as many as you want easier than "M". 2nd its probaly easier again to preset the offset and have a prompt using Enter to accept or type a new value it would ask this only once at start for multiple, if different value required multiple then yes exit do again save some accept steps. Same for layer. The posters above may consider incorporating these ideas into their code.

You should probably know about these 2 OFFSET lisps by Lee Mac too

These are just a couple of Lee's awesome lisps, very kindly made available for free on his site.

Thanks Lee!
