Richard,
Thanks for all the helps so far, you've been great. I have problem with Eagle and I'm stumped to find an answer. Before I send our boards out I prototype them here. Because we can't do certain operations like running the top layer to thru hole capacitors we need to stop the auto router from running the top layer to those locations. We have been using the restrict layer to keep the top tracks from those locations but this is tedious on larger boards. Is there a simple way we can limit track layers to certain packages? Maybe when 6 comes out if not now?

Thanks,
Robert

Richard,

I'm down to the silkscreen and the files must ship Friday. Suddenly, the silk screen layers have disappeared!! They (layers 121 and 122) do not show up in the layers list. What have I done to make them disappear and what must I do to get them back? I'm only slightly paniced.

I'm doing two board designs and the silk screen layers show up in one but not the other.

Thanks!
Mike

Richard,

Thanks to your help my project is almost ready to send to the fab house.

One problem I'm having is that the drc returns overlap errors everywhere I use rectangles. I also have the problem of connecting signals of different names (sub grounds) to one point - it returns overlap errors. Is there any way to give a rectangle a name or otherwise make it a part of a network so the drc won't return an error?

Thanks,
Mike

Hi Robert,

you have to draw restricted areas. As far as I know there are some ULPs that could help here. It is possible to route the nets by classes, there is a ULP that draws restricted areas on all pads on top layer. please look at http://www.cadsoft.de/downloads/user-language-programs/ and use the search function. "auto" should give some results.

Regards,
Richard
