venting question

I'm new at this. I'm moving a kitchen in a house I am rehabbing -- a one story with crawl space and attic. The sink will be further than 6 feet from the stack. First question is, does that mean I have to figure out an another way to vent?

Yes.

If you could post a picture or diagram, some suggestions could be forthcoming.

Thanks. I guess the picture keeps changing as I crawl around the attic and crawl space. I'll try to get a diagram drawn. Turns out there is a vent availabe that was put in for a laundry room and I think I can tap in. In the meantime a new question -- how far can the dishwasher be from the sink to share a drain? Does it need to be side by side or can it be next to it but around the corner? thanks

You can have the DW anywhere you can conveniently run the discharge hose to. In my kitchen, a U-shape, the sink is in the corner of the bottom of the U, and the DW is near the end of the opposite upright.
