I have created geopdf's from Mapinfo. But unable to measure distance within Adobe Reader X 10.1.1 as the tool is greyed out or disabled.
Any ideas why?
The tool needs to be enabled using Acrobat. For example, in Acrobat 9 you'd open the document and select: Comments > Enable for Commenting and Analysis in Adobe Reader
Advanced > Extend Features in Adobe Reader
