Eagle question

I am designing a board in eagle and I am wondering if there is a way to change the size of all of the traces at once? I want to increase all of them from 8mil to 16mil.

Depends on the board's complexity but this is one way.

  1. Zoom out to see the board.
  2. click the GROUP command
  3. Highlight the entire board
  4. click the CHANGE command, select width, select the new desired width
  5. (carefully) right click on one of the trace and select "Change GROUP"

awesome! That did the trick. Thanks!
