Adding the same attributes to hundreds of blocks

[Designer_1E]

Hello,

I need to add the same 7 invisible attributes to hundreds of different blocks, within one drawing.  Ideally they would be added to the base point.  I am searching for an autoLISP that can do this.  Any recommendations?

I have attached a file with the attributes in needed, if you are curious.

The AVC Properties Palette was created specifically for your task.  This is not LISP, but a powerful plugin. You can customize the AVC Properties Palette to show virtual attributes for ALL blocks. As soon as you fill in the values ​​of these virtual attributes, they will be immediately saved inside the blocks as invisible attributes. You can change the values ​​​​for all selected blocks at once. This properties palette also allows you to add and remove attributes for all selected blocks by simply entering a new attribute name. You do not need to enter the block editor.
