I do some unorthodox design using Eagle. I have always had problems controlling the dimensions (width) of my 'Thermals' when I generate a ratsnest/ground plane polygon. I believe it has something to do with the percentage to 'drill' size but could be wrong there. I've tried altering all DRC parameters but to no avail. Something is governing the Thermals to a certain width. Is there a way to dictate their widths? Thanks, Keith
