Topic: Getting the entinity name of a selection set

[iliekater]

I'd like to obtain the entinity name of a selected set . You see , I have used the ssget function to create a selection set of objects , set it on a variable , but I cannot get its entinity name . I want the entinity's name , in order to delte it (not the objects , but only the entinity - probably by using the entdel function) .
You may wonder why do I want to delete an entinity from the data base , instead of deleting the objects .
Well , you see , I have created a function that , among other things , selects some objects by using the Previous statement
( setq MySS ( ssget "P" ) )
then , at some point , recalls itshelf , but even if the user does not select anything , the command still selects the previously selected object , becouse the entinity still exists , even if now the MySS selection set is null ...

One way

Code: [Select]

       (setq i -1)
       (while (setq ename (ssname ss (setq i (1+ i))))
         (setq lst (cons ename lst))
       )       
another way
       

Code: [Select]

(setq lst (vl-remove-if 'listp (mapcar 'cadr (ssnamex ss))))
But you can use the command to erase the selectionset.

Code: [Select]

(setq ss (ssget))
(command "_erase" ss "")

PS to delete the list

Code: [Select]

(mapcar 'entdel lst)

Thanks CAB . I don't want to delete the selection set , I only want to delete (or turn nil) the entinity that was created when I selected objects using the Previous statement
( ssget "P" )
becouse that damn entinity still exists despite the fact that the user tried not to reselect anything .
As far as conserning the rest of the code you provided me , I am going to give it a look tomorow . Right now my eyes are closing due  to my fatigue . I am Aaaaaaaaaaaahhh falling ..... A  aa sleep ..
I don't ... de. ...
ZZZzzzzzzzzzzzzzzzzzzzzzz ....

The only way I know is by doing the following:

1. Draw a dummy object.
2. Call command "select" "last"
3. Delete the dummy object

What about saving the previous selection set before you do anything, running your routine, then reselecting the previous selection, so it previous again?
