Via holes to connect a layer to another

[davidepini72]

I’m working on the layout of the PCB and I need to use the via holes.
How can I use them?
How do I connect the via hole with the trace under the first layer (working in the second layer)?
Does it exist a tutorial about this argument?
thank you

Yes

So lets add a few vias. Activate the routing tool (hotkey x ). Click on pad 2 of R2 (The GND pad of R2 ). Press v to add a via to your cursor and move your mouse around. Notice that you know have a via at the cursor which is followed by a trace back to your starting position.

Tutorial: Introduction to PCB design with KiCad version 5.1 (Getting Started)

Improving the Layout We did only use traces to define the connectivity in the first round. We still have a full second copper layer that we never used. So lets introduce copper zones and vias to the mix. You will additionally learn how you get changes made in the schematic back into the layout and will also learn how to change the unit used in a schematic to allow for easier connections. We continue with the previous result. For convenience here the project as it would look like first_project_s…

thanks for your replay.
Now I have the necessity to put four mechanical holes (not via, but for fixing the PCB to our machine) in the angles of the PCB. Does it exist a command to realize them?

you can either add NPTH directly in PCBnew or add them via eeschema and import them.

I personally like capturing things like this (and logo’s) in eeschema

the holes can be found under the mounting hole footprint library

Introduction to PCB design with KiCad version 5.1 In this tutorial we will learn the very basics of using KiCad for designing a circuit board. It is assumed that you already installed KiCad. If not head over to KiCads download page and follow the instructions for your operating system. This tutorial is split into the following sections: Creating a Project Designing the schematic (Schematic using symbols and Wires) Lay out the board (Visibility options, Footprints, Traces and board outline) …
