I'm new at Eagle. I'm moving between schematic and board adding nets to the schematic then switching to the board and routing them. I'm doing this just to learn how to use Eagle. I notice that when I route the resulting airwire, it completely ignores the width specified in the class. For example, I created a class called TestClass and made the width 20 mils, drill 14 mils and clearance 14 mils. Then I created a net on the schematic between two smds and specified TestClass. Then I switched to the board, selected Route and routed the signal between the smds. The resulting wire was not 20 mils. It was 16 mils. So I created another class, TestClass2 that had a 10 mil width. Then I used Change -> Class to select TestClass2 and clicked on the routed signal. The width did not change. When I clicked on Information and clicked the signal, it was of type TestClass2 but the specified width remained 16mils. Can someone please help me understand what I am doing wrong. Thanks in advance.
