Need code to send a "CP" command

Please help!

I have a routine that will update a block attribute from another block attribute. It works well and is quite versatile.

Anyway, after selecting the source block the code asks to "Select Addresses" [see below]. At that point I have to type "CP" into the command window and hit the Enter key to select blocks with a polygon. I would like the code to go into the "CP" mode without me having to type it in.

 
 ;reset variables
 (setq tag_found nil)
 (setq setset nil)
  ; get end block
  (while (/= tag_found "true")
  (princ "\nSelect Addresses ")(princ (chr 34))(princ stag_end)(princ (chr 34))
  (setq selset  (ssget '((0 . "INSERT"))))

Thanks for any help.

When asked to select hold left mouse buton down and Drag

towards right is within window

towards left is crossing window

I appreciate the response but that won't solve my problem.

Normally, selections are oddly shapped. I need to just select the blocks that need updated. The selection may include 12 or more oddly shapped points.

Do the blocks that need updating/matching have the same name?

Try

(setq selset (ssget "_CP" '((0 . "insert"))))

BTW... it's all there in Developer Help under ssget

No that doesn't work, if you use "cp" with ssget you need to supply a point list.

I was thinking use (command "select" "cp" ....) then (ssget "p" etc.. but I couldn't get the "select" to end without user hitting "enter" so it doesn't save eliminate those dratted keystrokes

;reset variables
 (setq tag_found nil)
 (setq setset nil)
; get end block
  (while (/= tag_found "true")
      (princ "\nSelect Addresses ")
      (princ (chr 34))
      (princ stag_end)
      (princ (chr 34))
      (command "select" "cp")
      (setq selset  (ssget "p" '((0 . "INSERT"))))

works though. It's kinda ugly. I would prefer personally to not have the select prompt vanish automatically anyway.

I had to add a "pause" to get it to work, as in:

(command "select" "cp" pause)

(setq selset (ssget "p" '((0 . "INSERT"))))

Well the code does stop and lets me polygon around the blocks but the code won't run past that point.

I appreciate everyones help. I guess I will have to live with the original code.

Thanks again.

The code keeps running for me, but only after a few "enters" after the select.

No matter what you do you will have to tell the program when to stop when making a crossing polygon because it could be 3 points or 300. if you don’t want to hit the enter key change your right click on the mouse to be enter.
