ssget i issue 2012

[JohnM]

anyone having issues with ssget "i" on autocad 2012

it will return the selection set but when i follow it with a command function the command function gives me an error like the command structure is wrong.

it works in 2004 and 2006

 

example:

 

(defun c:test ()


(setq ss (ssget "i"))


(command "move" "previous" "")


)

 

i get an error

Command: TEST

Point or option keyword required.

; error: Function cancelled

when it should ask for a base point.

 

if i delete the ssget it works fine.

Maybe:

(defun c:test1 ()
(if (ssget "_I")
 (command "_MOVE" pause pause)
)
)

thanks for the responce

it does not matter what i do, the "ssget "i causes a problem with any edit command. move-copy-change-rotate

all these commands ask to select an object

that is why i used the previous option in the command. this is where it errors.

i use ssget i Implied selection (objects selected while PICKFIRST is in effect

to verify that a user has selected something on the screen

then it runs the command.

 

draw a couple of lines on layer x and have the program change the layers to layer 0

you draw the lines

then you select the lines

then run the program

 

this works. it finds the previous set

[font=Arial][color=#000000][color=#000000][font=Arial](defun c:test ()[/font][/color][/color][/font]
[font=Arial][color=#000000] 

[color=#000000][font=Arial](command "change" "previous" "" "properties" "layer" [/font][/color]
[font=Arial][color=#000000]"0" "")[/color][/font]


[color=#000000][font=Arial])[/font][/color]

[/color]
[/font]

this will not work

[font=Arial][color=#000000][color=#000000][font=Arial](defun c:test ()[/font][/color][/color][/font]
[font=Arial][color=#000000] (if (ssget "i")


[color=#000000][font=Arial](command "change" "previous" "" "properties" "layer" [/font][/color]

[font=Arial][color=#000000]"0" "")[/color][/font]


[color=#000000][font=Arial])[/font][/color] 


[color=#000000][font=Arial])[/font][/color]

[/color]
[/font]

i get this error:

Point or option keyword required.

; error: Function cancelled

(defun c:test  ()
     (if (ssget "i")
           (command
                 "change"
                 "_properties"
                 "layer"
                 "0"
                 "")
           )
     )

If there is an implied selection when you call the routine, then this will affect the behaviour of COMMAND call; seems that you didn't noticed that in my previous example.

(defun c:test ()
(if (ssget "i")
 (command "_CHANGE" "_P" "_LAYER" "0" "")
) 
)

thanks for the responce.

i just changed my program to use visual lisp functions and got rid of the command functions.

now all is working correctly

thanks
