Select by color. the fastest way!

QSelect in my opinion is still the fastest.

FILTER to me is the fastest because you can save a Selection Filter for future use so you don't have to keep going through the same procedure of selecting the necessary parameters. Unless, of course, you create a LISP routine.

No pun intended Mark. You still my boy, blue.

When does QSelect work and when does it not work? That should tell you why it won't do what you want.

The difficulty, I suspect, is that you have some lines that are red because they are on a red layer (or layers) and have the color ByLayer, and you may have other lines that are explicitly assigned the color red. Unless (as StykFacE pointed out) you have a filter defined for this task, you can't select all those items at once.

I'm curious: why do you need to select everything that is a particular color? If it's a plotting issue, you can adjust the color table.

Filter would be great. Pretty sure you should be able to locate a LISP already that can do this, probably at Cadcorner or Cadalyst.

More importantly you should try to determine the cause of Qselect not working.

I couldn't find tip #1046 in above site.

You got to know how to do it. Try this link:

Thanks your link reached the page.

I searched but no result were found.

So you downloaded the lisp routine and tried it out?

The key was to search on TIP1046.lsp.

I agree completely that both FILTER and QSELECT are the most robust options, but given the specificity of the OP's request, for fun:

SelectBySS

(defun c:SelectBySS (/ ss color)
 (if (and (princ "\nSelect object to select all by color: ")
          (setq ss
                 (ssget ":S:E" '((-4 . "<NOT") (62 . 256) (-4 . "NOT>")))
          )
          (setq color (cdr (assoc 62 (entget (ssname ss 0)))))
     )
   (sssetfirst nil (ssget "_x" (list (cons 62 color))))
   (prompt "\n** Nothing selected ** ")
 )
 (princ)
)

SelectByColor

(defun c:SelectByColor (/ color ss)
 (if (and (princ "\nSelect objects by color: ")
          (setq color (acad_colordlg (atoi (getvar 'cecolor)) T))
          (setq ss (ssget "_x" (list (cons 62 color))))
     )
   (sssetfirst nil ss)
   (prompt "\n** Nothing selected ** ")
 )
 (princ)
)

I downloaded it but I didn't know it is a LISP routine.

No I haven't used it and am not sure if I will, as I am not used to LISP.

There is a world of difference between WRITING a lisp, and using one.

You use lisp all the time, within the program now.

The EXPRESS TOOLS are mostly lisp programs, which you run by clicking on an icon, or entering a shortcall for it.

There is no reason to be gun-shy of USING them, they will save you lots of time and work.

Click on this link to Lee Mac's explanation of how to use them.

Once you have read the first two little bits you will understand how to do it, and use any lisp program.

After you see how easy it is, and how incredibly useful they are, go back to Lee's site and take a look at all of his wonderful lisp programs which he very generously makes available for free download there.

Thanks Lee!

Dear Dadgad

Thanks for your warm and supportive reply. You have encouraged me to go forward LISP. :)I am aware of its importance and benefit but I thought I am little old for studying it. But with your email I will definitely will dive into it.

Thanks a lot.

PS) This reply is one of the best replies I have ever got in this forum.

You do not have to know how to write lisp to use it just as you do not have to know how an internal combustion engine works to drive a car.
