Topic: SSGET Filter Issue

[Lee Mac]

Sorry for all the threads, but its one of those days... my head isn't screwed on properly today.

I have been trying to filter objects with an overridden colour, i.e. those objects with a group 62 code in their entget list.

I have tried to use an SS filter like:

Code: [Select]

(ssget "_X" '((-4 . "*") (62 . 0)))

But this just seems to pick up everything. 

Any help is appreciated as always.

If the object is set to bylayer, then the code is still there for the filter list, so just filter for entities where 62 != 256.

Code: [Select]

(setq ss (ssget '((-4 . "!=") (62 . 256))))

Many thanks Tim, you have been incredibly helpful today 

I am inexperience with the -4 group codes, but could I filter for ByLayer AND ByBlock, using this?

Code: [Select]

(setq ss (ssget '((-4 . "!=") (-4 . "<OR") (62 . 256) (62 . 0) (-4 . "OR>"))))

Thanks,

Lee

It's my turn to mind the store for a little while I guess.

I don't think you can do it the way you want, but you can do it this way.

Code: [Select]

(setq ss (ssget '((-4 . "<AND") (-4 . "!=") (62 . 256) (-4 . "!=") (62 . 0) (-4 . "AND>"))))

I think you can't do it the other way because you can't test the ' or ' call to be equal or not.  It is either true of false.  But this works on my simple test.

Code: [Select]

(setq ss (ssget '((-4 . "<NOT")(-4 . "<OR") (62 . 256) (62 . 0) (-4 . "OR>")(-4 . "NOT>"))))??

Thanks for the clarification Tim, but good call Alan

That's the way Alan.  Nice.   

You could also test to see if the number is between 0 and 256.

Code: [Select]

(setq ss (ssget '((-4 . "<AND") (-4 . ">") (62 . 0) (-4 . "<") (62 . 256) (-4 . "AND>"))))
