A great new tool that designers would use often is a free form measurement or ruler tool. The idea would be that initially one end of the measurement tool is anchored to a body or vertex or even any arbitrary point and the other end would be moving freeform in space snapping to the closest body or vertex or if nothing close, just moving freely in 3D space, and as this end moves realtime measurements are called out - specifically X, Y, and Z distances as well as the hypotenuse distance.
