I have a user that is using Acrobat XI Standard. He is using the measuring tool. Normally, when he has the scale ratio set, the units displayed when he measures on the document are read out in the second unit in the scale ratio. In other words, he has the first part of the Scale Ratio set as 1 Inch, then that EQUALS 40 Feet. (The PAGE UNITS is set to inches).
When he then draws a line (an inch long), the displayed number is 1. Normally, it would say 40 feet. He says he has been using it fine for many months, and today it reads 1 rather than the 40 feet.
In addition, it would usually say 1 INCH, if that is what it was equal to. This just says 1. No reading of units.
If anyone has a suggestion, I would appreciate it. I looked in the Measure Preferences, and the Properties. I tried toggling "Use Scale and Units from Document (when present)," that did not change anything. I toggled "Enable Measurement Markup," that did not change anything.
