Hi Danny, well I was thinking of:

Distance (pick 2 points and report distance between them).
Point (readout of x,y,z coordinates of a point that you pick).
Length (pick a curve and report length of the curve).
Area (pick a surface, solid or maybe closed planar curve and report surface area)
Volume (pick a solid and report volume).


I figured that would be a pretty good starting batch.

Is there anything else that you had in mind?

In the future I could add more advanced things like a curvature graph, etc... but I think a basic set would be best to start with.
