Hello Michael,
the output node uses clone and after an Apply the edges are unnamed - name of the brep is ok.

The tempobjects are only for preselections in a running nodeeditor for creating new nodes - I want only
evaluate the names and store them in the node. After connecting the brep data I want to
select the naked edges by the stored names for e.g. blend-nodes.
I will send You the complete code
next friday, because I am not at home.
And I have to investigate the input/output functions -
maybe the names are still present in the direct following node, but first I have to create a testnode.

Thanks in advance
Karsten
