VIA thermal trace width adjustment

Question

How would I change the thermal trace width for a via? I'm using a ground plane and have four little thermal traces for each via connecting to the ground plane. Mine are a little too small in width and I wanted to make them wider. I tried Edit-->Net Classes with a new entry, but that did not work. Also, I tried the wrench and various other things. I know I missed something. Thanks for any advice. Message was edited by: Allen Mitz

I found it. I am a new Eagle CAD user and am still learning things. This reply can be for the new users. I am using vias that are attached to a ground plane. When I create the polygon, thermals are created that connect the vias to the ground plane. To change the width of the thermal, press the "i" icon on your toolbar. Position your mouse on the polygon that your via resides in. Mine is the entire board that I am designing. My mouse was positioned on the side of the board where I drew my line to create the polygon (the line circled the entire board, but I just chose one side and placed the mouse on it). It was placed right on the line itself (before the ratsnest icon was pressed). Left click your mouse. The properties box pops up. The wire section should be at the top of this properties box. Choose "Width". A drop down menu appears and you can change the width here. My polygon was already created with the smaller thermals, but I changed the width with the existing polygon and it updated itself without having to redraw anything.
