Select the Title Block in a Worksheet with a single mouse click. In the Object Properties bar on the right-hand side, select EDIT (next to DEFINITION). Select the Title Block once again with a single mouse click. Select EDIT definition again. You should see Attributes with a $ sign in front. You can delete them from the sheet. You’ll need to save this as a new block to use again in this project, or if you want to use it in a template.
