Introduction
Once you have created a Viewport and set its scale, it is normal to annotate the viewport with its scale and/or use an attribute in the border stating the scale.
Using a field it is possible to automate this process.
First create your drawing, layout and viewport and set it to a suitable scale.
Adding a Field in the Titleblock to Reflect the Viewport Scale
By inserting a field in AutoCAD, you can add text to your titleblock in Paperspace to reflect the scale of the viewport or viewports. This scale text/label will automatically update every time the viewport scale changes. Type regen and press enter if you change the viewport scale.

The data field displays with a grey background. It will not print with this background, but if you want to turn it off, go to Options>User Preferences and untick Display background of fields.
