Page Turns Blue When Doing Measurements


Why your drawings turn blue when doing measurements.

Relevant Products

Bluebeam Revu 11 and above


Your drawing gets highlighted in blue whenever you try to take a measurement.

Why Does This Happen?

This happens in Revu 11 and above because the document contains at least one pre-existing Viewport which defines the scale and units of measurement.


You can remove the unwanted Viewports by following the steps listed below:

  • Expand the Viewports section of the Measurement tab.
  • Click the Clear All button to remove all of the viewports on that page.
  • Change the scale in the top Scale section of the Measurement tab.

Once you’ve cleared the unwanted Viewports, you can set a new scale by calibrating the drawing.
