Compared to Cycas, the measuring tool is not very featureful.
IMHO, it should be able to:
1) (Easy) Guage in 2 dimensions; eg select two points at opposite corners of a rectangle and get width, depth, diagonal lenght, area and angle;
2) (Harder) Work in both 3D and elevation projection mode, in which case giving X,Y,Z distances, linear length, 2 polar angles and plane area and volume would be the dog's...
