I have some parameters in a format that need to update when the format is used in a drawing. At the moment I have the parameters in a table allow them to be updated (in a note they don't seem to update and can't be used in a drawing, though they can't be changed). The parameters themselves can't be changed, but they can be deleted from (or replaced by similar text) the table, and then the entire table can be deleted.
Is there any way to prevent this?
