Add attribute to existing block

Hi,

    I need to add an attribute to the definition of an existing block so all the block of that tipe will have a new attribute.

Usally in Autocad I use two commands:

  • ATTDEF: to add the attribute
  • ATTREDEF: to re-define the block definition (and all the blocks)

How can I do that in Drafsight?

Tanks a lot.
