question about the delete subclass

It's difficult to know exactly what you are trying to do but... 

If you are deleting a non-package symbol you will need to select it by its name attribute.

i.e.

axlDeleteObject(car(axlSelectByName("SYMTYPE" "Old_Drawing_1"))

Nothing attached to an object that you are trying to delete can be fixed unless you use axlDBIgnoreFixed.

Dear eDave,

 thanks for your quick reply and help.

 so now I can follow your mathord, but first of all I need get the drawing's name. because I need delete the whole Old_Drawing_i(i=1,2,3,4....);using your code:

axlDeleteObject(car(axlSelectByName("Symtype" "Old_Drawing_1_name")))

so now I need to do is that judge the drawing exit or not and then get the relate drawing symbol name:just like:

Smathord_board-a-DRAWING-1121

1,how I can get it?

 LISTING: 1 element(s)

             < SYMBOL >            

  Symbol name:  Smathord_board-a-DRAWING-1121
  origin-xy:    (0.00 0.00)
  rotation:     0.000  degrees
  not_mirrored

2,I will delete this old_drawing_i(i=1,2,3,..) and then creat a new drawing change the drawing_i(i=1,2,3..) to old_drawing_i(i=1,2,3...)

for(i, 1, n
  obj = car(axlSelectByName("Symtype" sprintf(nil, "Old_Drawing_%d_name", i)))
  when(obj
    axlDeleteObject(obj)
    ...
  )
)

Hi,Dave

for(i, 1, n
  obj = car(axlSelectByName("Symtype" sprintf(nil, "Old_Drawing_%d_name", i)))
  when(obj
    axlDeleteObject(obj)
    ...
  )
)

is ok, but firstly I need get the value of Old_Drawing_%d's name.just don't know how to get it...

For delete,My code is :

if(axlIsLayer(Old_Drawing_id)!=nil
then
axlVisibleDesign(nil)
axlVisibleLayer(Old_Drawing_id t)
(axlClearSelSet)
 axlSetFindFilter( ?enabled list("all" "symbols"  ) ?onButtons list("noall" "symbols" ))
 sprintf(cmd "delete;pick 0 0;done")
 axlShell(cmd)

because it is a drawing symbol,so pick 0:0 will be OK for delete.

so I need to do is that automatic get the value of the Old_Drawing_id's name......

Your code makes no sense.

Old_Drawing_id is not a layer, it's a SYMBOL (isn't it?), so axlIsLayer won't return anything.

If you want to find the relevant layers, use unique(Old_Drawing_id ->children ~>layer). This return a unique list of all the layers used by children of the symbol.

Don't use axlShell, axlDeleteObject should work OK.

Get the name of an object by finding its name attribute. i.e. Old_Drawing_id ->name
