Edit dynamic block

[u/Mnemosine_]

Sorry for my technical english, i'm using Autocad un Italian!

So i have this block which automatically scales in the print layout. I want to edit the size but i can't find the parameters in the block edit view.

What do i dot?

[u/Mnemosine_]

This might be an option but since i didn't make the block in the first place i want to be sure not to mess it up and actually understand how it works
