Default Line Width During Gerber Generation

[Shubham_ee20s038]

Hi All ,
Few

Queries
a) I wanted to know the impact of the default line width ,when i generate gerber files for my PCB.
b) I need impedance control for my board , so do i need to generate anything in addition to the gerber files? if yes how do i do on KiCad ?

Hover your mouse for a few seconds over that text to see it’s tooltip:

All your tracks, pads etc have build in widths.
I’m guessing that this “Default line width” is used for the outline of the PCB if you draw that as an “extra” on some layers.

If you want to be sure for what it’s used, then you can generate a set of gerber files, then change that with, and generate another set of gerbers in another “output directory”, and then load them both in gerbview.
