# Restrict area trouble in Eagle

I am trying to get a small section of my PCB design to be ground-free as this is the advised layout given by the manufacturer of the component.

However, I believe that because there are components within this restrict area that are, or need to be, connected to GND, the restricted area fills with a ground plane that I do not want. Below are some related images.

The red line indicates my desired restrict area. Ideally I would like this area to be free from the surrounding ground plane and I will route the components that are required to be connected to ground manually with a few tracks.

Alas this does not happen and below is the actual result I get once I have 'ratsnested' the design.

As you can see, the area has indeed filled in with the ground plane, although it is a separate one to the main one, it is still an issue. So I would like it not to fill in at all!

Is it possible to do this on Eagle?

I need it because it is what the manufacturer recommends for the layout and it has proved problematic already without following there guidelines so I would like to rule out any possibility for problems in the future.

Just draw a polygon in the 'Restrict'-layer. This will prevent EAGLE from placing any copper there automatically. The following picture shows an IC placed within a GND plane. All pins (except one) are connected to GND in the schematic, and a polygon is drawn in layer tRestrict. A ratsnest calculates the GND polygon, and as you can see, EAGLE does not do anything inside the restrict-polygon. It is still possible to draw tracks by hand, as I did.
