Topic: Issue with SSGET

[Guest]

I've got some programs that I originally wrote for 2004 & 2007 that used

Code: [Select]

(setq a (ssget))
Now it seems I have to use the following to make the programs work.

Code: [Select]

(setq a (ssget "P"))

Have there been some "behind the scene" changes to how SSGET works??

I used ssget without arguments in 2008 with no problems. so I don't think that it's something Autocad did.

Not too helpful I know, but it's all I got.

<guess> I know you're a DIYer so look into the pickfirst sytem variable and the ssget "i" option (implied selection for objects pre-selected when pickfirst is enabled) to consistantly have your proggy sport the behavior you desire. </guess>

I was messing around with those options a little while ago and so far... no dice!

Just to give you some background/insight as to what I'm doing, here's the code.  All I do is push a button and the program is run, only now I have to select the objects whereas before, I was able to select them PRIOR to pushing the button.

(defun C:MyCopyBase ( / a len)
   (if (setq a (ssget "P"))  ; <-- Used to be (if (setq a (ssget))
      (progn
         (command "copybase" "0,0" a "")
         (setq len (itoa (sslength a)))
         (prompt (strcat "\n " len " Objects have been copied to the clipboard."))
      )
      (prompt "\n No objects have been selected.")
   )
   (princ)
)

And oddly enough, when I select the Copy with Base Point item from the Edit pull-down, I get the same thing.... it prompts me to select objects even though I already have them selected.  I still can't help but think there's something geeked out in the selection options.

Try setting system variable "PICKFIRST" to 1.

It already is.  Got anything else?

Looks like I found the culprit...

Code: [Select]

(command "-plotstamp" "l" "n" "" "")
I added this line to a custom program that is loaded with each drawing and when I removed this line, SSGET works like it's supposed to.  So now my question is... WHY??!

I think there is a CANCEL somewhere, so the selection is turned off again.

Also I agree with MP that you should have to use (ssget "I"):

Code: [Select]

(defun C:MyCopyBase ( / a len)
   (if (or (setq a (ssget "I"))(setq a (ssget)))
      (progn
         (command "copybase" "0,0" a "")
         (setq len (itoa (sslength a)))
         (prompt (strcat "\n " len " Objects have been copied to the clipboard."))
      )
      (prompt "\n No objects have been selected.")
   )
   (princ)
)

Are there new additions to the PICKFIRST variable that may have changed some of the previous values in 2008?  Just thinking out loud.
