FIND DYNAMIC BLOCK NAME THAT was STRETCHED , ROTATED

[amyyoyo1]

I am currently working with a routine that will pick up all the blocks inside of a drawing and compare it with a list of block names that I had,and use it to make a legend.

when I was testing the routine I realize that if the block had being strectched, rotated or changed from symbol with text to just symbol, the routine won't pick up the block name ,becasue autocad will assign a new name to it in the entity list (some thing like "2 . U324")which something I didn't know before.

I still really new to autolisp, and I sure someone here will know this long ago. It's there an otherway for me to pick the orginal block name not the autocad assign name?

thank you.

Dynamic blocks,

after modify some dynamic property, becomes a anonymous block, to retrieve the block name, as a vlaobject, use the effectivename propertie

i.e.

(setq obj (vlax-ename->vla-object (car (entsel "\nSelect a DynBlock : "))))
(setq name (vlax-get-property
      obj
      (if (vlax-property-available-p obj 'effectivename)
        'effectivename
        'name
      )
    )
)
