Here are the reasons why you should use AutoCAD blocks. If you haven’t used it, this perhaps can encourage you.
You can add objects from your drawing into your AutoCAD block. You don’t have to open Block Editor and recreate/copy the objects there. See how to do it here!
Want to prevent AutoCAD asking you to change attribute value, when you insert a block? See how you can set some attributes for not being asked when you insert the block here.
