I support this idea 100%. I've got a couple of (visualisation) jobs 
tentatively in the pipeline which will involve needing more careful 
measurements, and I'm certainly not looking forward to doing this in 
Blender as it's measurement capabilities currently stand.

I think the method you propose is great, and nice and flexible too - 
i.e. create a mesh with two edges, and you have an instant 'ruler' 
tool. It'd be great if you could get something working to play with, 
since it's a bit hard to make decisions like Ton mentioned (Draw on the 
full mesh? Only selection?) without seeing it in practical action.

While 'pure' CAD (from, say, an architect's perspective) is quite 
different to 'pure' character modelling, there are plenty of domains 
with a great deal of overlap in between - especially things like 
visualisation. Splitting things up would complicate workflow 
unnecessarily, if we're just talking about things like a 'Draw 
Measurements' toggle button.

Cheers,

Matt
