Curves join issue

hello guys,

i tried to join these curves in the file, but funnily most of them disappeared.

When trying to join them after exploding the polycurve it works fine.

you can take a look at the file attached.

thx,

Hi Benjamin -
if you explode all curves and then run SelDup, a duplicate curve will be selected. Delete that. Then join.

Did you experience also that som of the curves disspeared after trying them to join?

thank you,
