Might be worth noting that a similar case exists for teardrops, which most fabs will prefer to have in place. Potentially more catastrophic for voltage clearances, S, RF and microwave applications.
As always, if your sensitive to it then constrain it, analyse your assumptions, and communicate your requirements and expectations clearly.

Looking forward to your reply. Regards, Sylvia __________________________________ Yahoo!
