Block name same as drawing name

[sakinen]

Im building a lisp that is going to automaticaly make a block with the same name as the file thats in. With what function i can do that?

With what function i can do that?

Do what? Make the block? Get the Drawing filename? What part do you need help with?

[sakinen]

Sorry, my question was a little bit clumsy. I need to Get the Drawing filename.

[Lee Mac]

Two ways:

(vla-get-Name
  (vla-get-ActiveDocument
    (vlax-get-acad-object)
  )
)

(getvar 'DWGNAME)

That should lead to an error:

'BLOCK is self referencing'

-David

Will this have the same effect?

 
(command "-wblock" (vla-get-fullname 
                      (vla-get-activedocument 
                       (vlax-get-acad-object))) "Y" "")

'BLOCK is self referencing'

I’m afraid that there is no restriction for having a block with the same name as the drawing that contains it - just tested in 2008 and 2010.

Make a drawing with a block with the same name defined.

Try inserting that dwg file into a new dwg file. You should get an error/ warning. -David

While this is true, not everybody inserts blocks in this way.

Perhaps if Sakinen could say what exactly he's trying to achieve (i.e. why he needs the block's name to match the drawing) we may be able to help some more.

In 2000 it errors out


Command: -insert
Enter block name or [?]: testb
Block testb references itself
*Invalid*

So in general, it is a bad practice, in real world scenarios, it is an unacceptable format. -David
