Make hobbyist PCBs with professional CAD tools by modifying "Design Rules"

Step 12 But why stop there?

We could stop there, but we don't have to. The autorouter operates on a grid (defaults to 50mils), so what it's done is put tracks along the grid in places that don't violate the design rules. That probably means that there's significantly MORE room for even wider tracks or clearances. If we GROUP the entire board, we can "change width 1.0mm" or equiv, and use the DRC "check" option to see if we STILL pass our specs. Or we could have
another DRC file with different parameters. In fact, this board can have it's trace width increased to 1.4mm without violating our clearance rules:

 Where, exactly, does one find the menu option to increase the trace width?

There's a much easier way. Just select the "i" tool and then click on the thing you want to change. It will bring up a dialog box that let's you change most of the attributes that apply to whatever you clicked on!

I just found that you can use the "change" tool (looks like a wrench) and select a new width from the dropdown.  However, you have to click on each trace segment in order to change it.  Can anyone help on how to automate this for changing many traces?

Select the change tool, setting "Width" and the desired width. (The author is saying that you can do this by typing "change width 1.0mm", but you can select it with the mouse and the wrench tool as well). You can then select the "Group" tool and select everything to be changed. Then right click on any part of the selection and choose "Change: group". This will change all selected traces at once.
