i primarily use this iPad app in the field for field surveys. The current app, unlike the old app, doesn't allow me to place a dimension line without a scale being set to the page. when i am in the field taking field measurements, being able to manually place a dimension line and manually enter the measurement is really required. i could use the pen tool and just draw it, however, that kind of defeats the purpose of using an iPad - i could just use pen and paper. the dimension line always makes it legible and keeps the line straight. this is a huge advantage to use using pen and paper. i also use this feature to take dimensions on photos - if i am in the field and i need to capture information in elevation, i will take a photo, put it on my sheet, and add these manual dimensions right on top of it. that's not something i can do with pen and paper and something i am really missing from the old Bluebeam app.
