hello,

i'm new to this wonderful software so before posting i've read tons of tutorial e reference manuals.
I'm using the evaluating v1 version and didn't understand how to join different surfaces.
In the attached file there's a ama(a part of a boat) and i would like to join the two part of one side and the 2 opposite corners in order to have 1 single lateral face.
i've tried with join, fillet and union but nothing happens. where i'm mistaking?

thanks

bye
