When I select a measurement tool in Bluebeam Revu, my page turns blue. What’s wrong?
OR My measurements don’t match my calibrated scale.
It sounds like there are some Untitled Viewports created by AutoCAD that are corrupting the calibration in Revu. These can be caused by several things. Some PDF writers create multiple overlapping Viewports and some create Viewports with different X & Y coordinates. The scale and units in the Viewport take precedence over the Scale at the top of the Measurement Tab, so these Viewports prevent you from being able to calibrate or take accurate measurements unless they were placed there on purpose.
To remove these Viewports, open the Measurements Tab (Alt+U) > Scroll down to the Viewports section
> Click the “Clear All” button.
