Text can serve as a placeholder for information. That can be useful but unfortunately it's not a very graphic representation. To make it more graphic you can use the 'Block on Text' command. With the command you can select TEXT and MTEXT entities. With the command you can place a block on text with the content you choose. If you want the blocks is placed in the same angle as the text entity. When you don't need the text entities anymore you can let the command erase the text straight away.
