Hi Andreas,

I found that place, but how can the Informations on this site help me to
understand, getting access to the vertices for an edge?

I don`t understand. 

Anyway thanks to Laurent. His Informations helped me much.

Last Question:

Finite_facets_iterator it:
I would like to get the edges of a facet. What`s the correct method for
this?

Best
Dennis
