Associating nets to track dimensions

I’ve been using KiCAD for a long time but I cannot seem to perform a simple task that I’ve done many times before. I’m using v 8.0.4.

When I go to File>Board Setup>Net Classes, I cannot see the netlist of all the nets as I think I should so I can’t assign different tracks sizes as needed.

I’m sure it’s something simple.

What am I missing?

Hi, see the documentation here:

You can assign using patterns, or graphically by right clicking on the wire on the schematic, or by editing the netclass property of the net on the schematic. Note that for the last two methods you need to create the netclass first in the setup info.

Then for the trace width you edit the netclass values in the PCB editor setup.

For others reading this:

I am sort of missing the simplicity of the old interface of assigning net names into net classes. What do people here think about combining those two methods, so you can use the wildcards to assign the bulk of the nets, but have some click or drag interface for the odd left overs?

I am missing an overview of net classes with net names. For example how do you get a list of all net names without a net (a.k.a. default netclass) in the schematic editor? In the PCB editor there is the Inspect / Net Inspector, but it’s missing the “netclass” column. (That is worth a feature request I think).

Is there a schematic?

Agree. I used @retiredfeline suggestion and it works fine. I’m revising the design done by another. What I found is that if there are existing traces with a width different to what I want, KiCAD defaults to the existing (one I don’t want) trace width. Delete the old traces, and KiCAD then uses the desired trace width.

Yes, KiCad has a special button for that. It is:
