Is There a Way to Increment the Selection Set Name in a Loop

[mgorecki]

For example I have a number of rectangular polylines on a layer.  The groups of rectangles have different sizes.  I'll ask the user to select a group and I want to store them in a unique selection set name, then loop and have them select the next set and store them in a unique selection set name, and so on.

Any ideas on how to do this?

Thanks

This is a job for the (set) function, in which you can construct a variable name involving other functions.  In your description:

(setq n 0)

(while

  (set (read (strcat "ss" (itoa (setq n (1+ n))))) (ssget '((0 . "LWPOLYLINE") (8 . "YourLayerName"))))

)

That will save the first selection to a variable called ss1, the next to ss2, etc.

list 'em like that

(setq sset_list nil
      loop t
)
(while loop
	(setq sset_list (append sset_list (list (ssget))))
)

and then get each sset usins nth function.

(sssetfirst (nth 0...n  sset_list))

Hi Kent, thank you very much!

Thank you very much as well, I though about using a list.

Any reason why you would not make a list ( (layer entityname)(layer entityname)(layer entityname)....

The list could have even more items (layer entityname area length) etc. You can sort the list based on any sub item.

[Nothing in the request relates to Layers.]  A big difference:  my solution puts entire selection sets, of any number of objects, not just one entity, and on any number of Layers, into incremented-name variables [see the Topic heading].  But the OP would have to say whether that list approach can serve their purpose.

And here I thought it stood for Lost In Stupid Parenthesis 😄

Hello, no particular reason except that I just wanted to have different selection sets to manipulate later in the code.  I agree, Lists are very helpful, I use them a lot.
