delete invisible attributes help
« on: December 17, 2010, 11:06:59 AM »
Hello

I'm trying to delete invisible attributes in a drawing.  I don't want to burst the blocks.
A client uses some CAD software which displays the invisible attributes, so I want to remove them all together.
I found this lisp here http://forums.autodesk.com/t5/Visual-LISP-AutoLISP-and-General/Remove-Invisible-Attributes-from-Blocks/m-p/1517876

Code: [Select]
(defun delInvisAtts (bname / )
(if (tblsearch "BLOCK" bname)
(progn
(vl-load-com)
(setq blk (vla-item
(vla-get-blocks
(vla-get-activedocument
(vlax-get-acad-object)
)
)
bname
)
)
(vlax-for ent blk
(if (and (eq (vla-get-objectname ent) "AcDbAttributeDefinition")
(eq (vla-get-invisible ent) :vlax-true)
)
(vla-delete ent)
)
)
)
)
)

But I can't get it to work, wondered if somebody could show me where I'm going wrong?


Thanks P

That only deletes them from the definition, not the inserts.  You would have to get the inserts for said block, and then step through the attributes associated with the insert, and then delete those if they are invisible.

Something like this?

Code: [Select]
(defun c:DIA nil (c:DeleteInvisibleAttributes))

(defun c:DeleteInvisibleAttributes ( / ss ) (vl-load-com)
  ;; Example by Lee Mac 2010 - www.lee-mac.com

  (if (ssget '((0 . "INSERT") (66 . 1)))
    (progn
      (vlax-for obj
        (setq ss
          (vla-get-ActiveSelectionSet
            (vla-get-ActiveDocument (vlax-get-acad-object))
          )
        )
        (mapcar
          (function
            (lambda ( attrib )
              (if (eq :vlax-true (vla-get-Invisible attrib))
                (vla-delete attrib)
              )
            )
          )
          (vlax-invoke obj 'GetAttributes)
        )
      )
      (vla-delete ss)
    )
  )
  (princ)
)

Perhaps, command _.attsync helps?
Sorry for my English.

thanks Lee.  It works very well but there is a small problem.
The tag and prompt order becomes messed up.

In this example the 'No' and 'code' attributes are invisible

before:

after:

Hmmm.. I wasn't expecting that  :oops:

Perhaps altering the block definition is the only way  :|

Try erasing them from the definition, and the insert.  Run the code in the first post, and then Lee's ( either order, doesn't really matter ).

Or perhaps use AttSync I suppose after running the first code  :|

I would have thought one could alter the attributes for a single reference though  :-(

I think the problem is with Acad's logic when it comes to attributes.  There is nothing referencing the definition ( of an attribute ) once you insert a block.  I have wondered how it happens before, and could only come up with the idea that is just goes in order, as it appears it does.  So if you erase the invisible attributes from the definition and the insert, then they should be in the same order.

Sidenote:  I wonder why they didn't just put a prompt dxf code with attributes references.  They are only stored in attribute definitions.

That seems to be the case judging by the way the prompt order depends on the Sortents table of the block.

That would be nice :-)

thanks guys.
I'l give the first lisp and attsync a go.

to be honest I'm a little bit confused about how to run the first lisp as its a function.
What is the corect syntax for running it?

Cheers

A slight reworking and a wrapper for you:

Code: [Select]
(defun delInvisAtts ( bname ) (vl-load-com)
  (if (tblsearch "BLOCK" bname)
    (vlax-for obj
      (vla-item
        (vla-get-blocks
          (vla-get-activedocument (vlax-get-acad-object))
        )
        bname
      )
      (if (and (eq (vla-get-objectname obj) "AcDbAttributeDefinition")
               (eq (vla-get-invisible obj) :vlax-true)
          )
        (vla-delete obj)
      )
    )
  )
)


(defun c:test ( / bn )

  (delInvisAtts (setq bn (getstring t "\nBlock Name: ")))

  (vl-cmdf "_.attsync" "_N" bn)
  (princ)
)
