My apologies. I had thought the discussion was about Euclidean
constructions.

Agreed, and I agree with her point on that also. However, I still stress the
need for "finesse". Students, still having open minds about what they see and
absorb, need to see from the start what is as close to the reality [albeit
abstract] as possible. So I comment again that drawn lines should be as thin as
is reasonable, and not be thick blotches. If that were the only means of
drawing constructions on that medium, I would abandon it, momentarily, in that
case in favour of something more favourable.
David.
