I think this is a cool idea. I would think Protel would most certainly be intrested in helping, it adds value to the product. They already have standards in place and would want us to work to the same standards. That may be the only drawback to Protel involvement, unless we agree with thier

Andrew et al, I get the feeling that many people think that there would not be too many footprints. How many is not too many? My SMT+ footprint reference has 2474 footprints and adds at least 50 - 100 per year. Now a large number of them would not typically be used by any one user but

Dennis, What I meant to say is that Protel offers up to 32 signal layers, therefore the fence would be located on the 30th signal layer. since this is a conductive layer you can set design rules or clearance constraints for your components. It would solve the silk screen pad violations,

Under no circumstances should the Protel libraries be copied! They are riddled with errors (I'd list them all as unverified). For instance, any metric pitch component that's been created with the footprint wizard is likely to be wrong. The biggest hurdle I forsee is the widely differing
