Pcb track to hole

I am replying to my own topic as I have further development.

I could not connect to a hole with copper round it, but I found I could lay down a via pad and connect to that. So I could easily solve my initial problem of laying down 4 pads for an ac to dc module.

But the question is: my pcb design is single sided. A via would normally be used for double sided. So what effect will this have on the Gerber file? will it cause an inconsistency or any other problem?

Thanks
