If users do not want to show dimensions value for a particular reason, they can make the dimension contents permanently blank by following the steps below:

1. Create a new dimension style in the dimension style dialog box.

2. Go directly to primary units tab, on prefix blank space, type in:  \H

3. If you are using a precision unit like: 0,0, you must type \H on suffix as well.

4. Click OK button and set current your new dimension style. Done, just try it!
