Selection Sets w/Wildcard??

We work on alot of drawings converted from Solidworks and we typically delete Solidworks specific blocks. What I'm wondering is

if it possible to create a selection set that uses a wildcard.

(or the correct way to accomplish the same thing).

Here is a sample of how I know how to select one of the blocks

(setq aa (ssget "x" '((0 . "INSERT") (2 . "SW_CENTERMARKSYMBOL_17"))))

All the blocks have an "SW_" prefix.

Is it possible to select something along these lines?

(2 . "SW_*)

If someone could provide some direction it would be greatly appreciated!

TIA!

Have you tried?

All SelectionSet filter lists can use Wildcards, so as long as you are conversent with them, then the possibilities are endless.

Thanks!

Personally I hate when someone asks a question about code but doesn't post

what they did to make it work. I like to see others solutions.

With that said, here is my simple little app..

(defun c:SW ()

(setq aa (ssget "_X" (list (cons 0 "INSERT") (cons 2 "SW_Cen*"))))

(command "Erase" aa "")

(princ))

I'm sure I can't be the only person who didn't know how to do this..

Thanks again!

If I might make a slight modification...

(defun c:SW (/ aa)
 (if (setq aa (ssget "_X" (list (cons 0 "INSERT") (cons 2 "SW_Cen*"))))
   (command "_.Erase" aa "")
 )
 (princ)
)

Since you are defining the filter parameters instead of receiving them from a variable, you can also use:

'((0 . "INSERT")(2 . "SW_Cen*"))

No worries, glad you understand

See!

If you don't post YOUR code you can't learn better ways of doing things!!

Thanks guys!!
