@Efi Fogel: thank you for the reply

But I have got still the same problem. I have to solve it to continue my 
program.
I get the source and target of the curve with:

*eit.source()->point();
*eit.target()->point();

Please give me a hint, how I get the information for constructing the curve.

Thank you very much,
Paul
