ERROR Net Antennae

[robertferanec]

It looks to me like there is no GND plane. Did you assign GND net to at least one of the planes?

PS: Have a look here, this may help you to assign a net name to a plane: http://www.fedevel.com/welldoneblog/...e-new-old-way/

I have this error (Net Antennae (Tolerance=0mm) (All))
and all are for the opcion Place Via.
How can I fix that?

I am working with the first course (Switching Power Supply Design Course - Part 4)
