Title: Can't purge *A blocks
Post by: jbuzbee on December 17, 2018, 09:00:13 AM

I have a bunch of blocks in a drawing that are named *A000. Does anyone know what type of blocks these are?

Thanks,
j buzbee

Usually anonymous blocks are *U#. Are you sure these blocks aren't referenced somewhere? Post the drawing if you can.

Open the block definition with the VLIDE.  You can step through the entities in a text format, which can be handy if the block is empty or has hard-to-see content.

Annotation scaling objects, e.g.

dictionaries (root)
-> (dictionary) "ACAD_SCALELIST"
   -> Pointers to anonymous blocks   

or ...

Annotation enabled object (e.g. dimenstion)
-> Extension dictionary
   -> Dictionary
      -> (AcDbDictionary) Dictionary
         -> (AcDbContextDataManager) Dictionary
            -> (ACDB_ANNOTATIONSCALES) Dictionary
               -> (AcDbAlignedDimensionObjectContextData) Anonymous block
                  -> (AcDbScale)
                     -> Data for the scale, description & values
