For the Moasure App to display an area calculation, the shape or area measured needs to be a "closed" shape.
We would recommend starting and finishing at the same place (or as close as possible). You can also turn on "JoinStart/Finish points" to tie your start and endpoints together. You can do this using the tools icon within the measurement screen and selecting "JoinStart/Finish points".
You would also need to be in the 2D view (first icon) to see the square footage. In the other views, the sq. ft calculation will not show.
