I am an archaeologist using a couple of different drones to make models of things like prehistoric earthworks, mounds and historic buildings. I have made many models with good success, and every time I show a model to someone two things happen. First, they say, “that’s awesome”; then about three seconds later, they say, “what’s the scale”? As archaeologists, and assume just about every other profession, images, videos and models aren’t very useful without a reference scale. Having a floating scale bar that adjusted as the model moved would be a great addition to the software and propel the models from simply being cool or only useful to those manipulating it in the software, to something that could be useful to anyone.
