Topic: Block name entity Anonymous?

[dubb]

I'm not sure how to phrase this question.

When I am listing the entity properties for a certain block. using

Code: [Select]

(assoc 2 (entget(car(entsel)))) I get

Code: [Select]

(2 . "*U237") I am trying to obtain the block name. But I think this is the anonymous name?

How do always get the block name. I am writing a script to give me a list of block names for an entire selection set.

If it's a real anonymous block, then "*U237" is the block name.

If it's a dynamic or parametric block then you need the effective name.

I use UnAnon.Lsp by David Bethel for renaming an anonymous block.  It's on his free lisp page: http://www.davidbethel.com/lisp/

Thanks, I wonder why they make it more complicated.

Thanks, I wonder why they make it more complicated.

Because it needs to be.  If the block name wasn't unique, then changing one dynamic property would chance the properties of *all* instances of that block.  While that may be desirable in some circumstances it would really neuter features like having one block definition with multiple visibility states.

aH..That makes sense.

Thanks to your explanation, I found out if I resetted all of my dynamic blocks, then generated a list of blocks, I didn't get anonymous block names.

This is not necessary - did you read the content of the link provided by Crank?

[dubb]

I reread that, and I think I'll try implementing that method into my block listing script.

Would u please offer the lisp here   ?

The link doesn't work for me   !!!!

Thanks

@ahsattarian:

Try an interner search for "UnAnon.lsp".  The code is posted on several sites.

Unanon.lsp will probably need updating as IIRC it has an error routine that contains command call(s). This will cause an error in AutoCAD 2015 and later.

Yo tuve este problema y lo solucioné borrando el bloque anónimo y después insertándolo pero eligiendo el nombre verdadero del bloque.
I had this problem and I solved it by deleting the anonymous block and then inserting it but choosing the true name of the block.

I believe I updated the attached version to use command-s in 2016. Don't need it often but always saved me when I needed it.

David Bethel thanks again!

I use this for getting the name of blocks.

Code - Auto/Visual Lisp: [Select]

1. (defun blkName (vlaBlk)
2.         (if (vlax-property-available-p vlaBlk 'effectivename)
3.                 (vla-get-effectivename vlaBlk)
4.                 (vla-get-name vlaBlk)
5.         )
6. )
7.
