Consequentially, hole sizes may vary among footprints or not match a vendor???s available drill availability unless manually adjusted.

-- Some PCB fabricators have a finite set of drill sizes available. In this case loading a vendor file will automatically adjust the layout???s hole sizes to agree with the vendor???s drill availability. -
-- Many current PCB fabricators offer any drill size within a tolerance with just a minimun and maximum. In this case the layout???s holes do not need to match specific drill sizes but it may be desirable to normalize the hole sizes. While the user may want all holes consistant for asthetic reasons there may be a fabriction cost cost savings if hole sizes are consistant. Likewise, design rules, such as trace width and minimum seperation, can impact fabrication cost. In this situation the drills listed in the vendor files would not be specific drill availability but rather normalization values. -
