[kde-edu]: how to copy a length in kig

[Philipp Marek]

Hello everybody!

I'm trying to paint some graphics with kig 0.6.1 but I'm stuck on a problem.

I have a line l1 with two points A and B, and another line l2 with a point M.

Now I'd like to take the distance from A to B and measure it on l2 from M in 
one direction.
How can I do this?
It should be dynamic as everything else; so just reading the length and 
setting a point in the approximate distance is not what I want.


Help, please??


Regards,

Phil
