Using the Virtuoso autorouter: routing grid

RVERP

How do I set the routing grid? I can use the option to route on the routing grid, but I can't find how to check it's value, or how to set a new value.

I want to force the autoroute to place spines/vias on the exact grid I want, so I suppose the routing grid is what I have to use.

    All the pins are also on the layout grid. The router goes rogue the first turn he has to make, and returns on the routing grid when it connects to the destination pin (since it is on the routing grid). The shapes he has to route around are on the manufacturing grid.
    The default vertical and horizontal offset is set to 0 in the process rule overrides.
    To what is this offset related to? Is it the offset from a nearby shape? That can explain it maybe.
