Hello,

There are a few reasons I can think of that will make this happen or appear to have happened.

1) You have not run the RATSNEST command to process the polygon.
2) You have not named the polygon to the correct signal for the ground plane. If this is the case, use the NAME command to rename the polygon.
3) You do not have anything currently connecting to the ground plane. EAGLE will only process a polygon that has connections to it so as soon as you drop a via to connect to it it will fill.
4) You drew the ground plane shape with the WIRE tool rather than the POLYGON tool.

Best Regards,

Rachael

Unless the OP actually means his fill is stripy rather than solid, in
which case the question is when he's seeing this. Users who print on
transparency for home etching often report this due to issues with
printer drivers.

Thanks, but all your suggestions were done but the problem is still there, Please have a look at my PCB...

It looks like this is from a gerber file. Zooming in closer to the board
will probably make the board look normal. Solid fills are similar to a
raster fill, so the graphics renderer of the gerber viewer is trying to
draw each line of the rasterized fill. The gerber itself should be fine
for fabrication.

See the attached images for zoom level examples using gerbv showing this
behavior.

Ok. I've sent the Gerber files to PCB house and let's see what happens. I will let you know the results. Thanks.
