use of the topologizer

hello again :)

i want to use the topologizer component to clean up a curve network (i want to delete lines wich are to times in my model), generated by the hexagonal lunchbox component. later i used the fillet component to get round edges.

my problem now is, that the topologizer needs lines as input, but after the fillet component, i get curves. i found some articles, that i need a vb code or something like that?

does someone has a solution for me (again:D)?

thx!
