We use http://www.freedfm.com. Our CAD program puts text in the plots (identifying which plot it is), and freedfm raises all sorts of clearance problems on the text (the dot on the i in Obispo is too close to the rest of the i). I look through the reported errors and, if there is nothing other than the text, go ahead and order the boards. They turn out great!
