Shape to route keepout gap?

Hello all,

Im having a hard time figuring out why my copper shapes are not butting up to the route keep outs edge.  Its putting a 0.03 mil gap between them. I assume its a preference setting but i cannot for the life of me find it. Any help would be appreciated. 

Thanks!

Chad

    Oops, are you saying that artwork is ot exctly what i see? What is the REAL thing thath drc check use? On some board, i haveto GARANTY a certain spacing minimal value (legal requirement). We already add 10µ to this value to avoid calculation errors but if allegro use different one....

    I believe what this means is that if you make the correct size keepout, the artwork exports voids will be that exact size. Showing element on the shape void in allegro with give you the incorrect radius size... as oldmouldy said, allegro adds a gap to avoid rounding issues. So , instead show element on the keep out you've created, that should be the size you intend to use.  There is no DRC check (that i know of) for shape to route keepout spacing.
