Hi! I am just new here and also a newbie in doing lisp routines. I was wondering if there is an autolisp that could possibly delete a text value of a specific attribute text inside a block of a block. I don't want to totally delete the attribute, just the value. I already tried several examples on the internet but doesn't really get to my satisfaction and as to how I want it to be. The only available lisp routine that I found so far is just yes, deleting the value but only works if the block attribute is outside the title block or even inside the title block itself but not when the attribute block is already inside a block of the title block. I need to do this for over 80 drawings and I was hoping to not doing it in an old fashioned way of opening each drawing just to edit-in-place the title block and then deleting the value of that attribute. Can anyone help me please? that would be very much appreciated. Thanks in advance.
