Gregg, I would reccomend using a third party gerber tool to review the data being released. ACT has a tool that will allow you to review and check your data. You may find them at [http://www.ecam.com]. I am a designer that uses a gerber tool to review the data before it is released. I do the following: 1. read the data in the format I will be releasing including the drill file. 2. do a check on apertures being used, minimum spacing and annular ring parameters. 3. generate check plot for each layer on a laser printer for visual check. This may seem like a lot of extra steps. But if you catch a problem now, the cost is minimum compared to having start the job again. Mistakes happen...I like to catch my own errors before they become major problems. A seasoned CAM operator would have questioned this. However, if this happened on a quick turn. The data checking is not always as complete. In a previous life I managed both a CAM and a CAD department. We would get requests to just quickly layup the tooling and shoot it out. The boards were fabricated to match the supplied data and nothing more. Doing a complete check for possible fabrication issues takes good tools and time. And we know time is money, not to mention the costs of maintaining the cam station. If this happened on a production run, you need to sit down with your account rep and hash this out.
