Questions about using PCB Editor routing

Hi all Friends
Hope you are doing fine
I have 2 important questions on PCB Editor
1- when I place components manually, I want to place some of them on the buttomn layer rather that top layer but I do not know how to do that and how tomake sure that they are placed on the buttomn layer:?:

2- I have a 4 layer board and I defined my layers but when I run autoroating it just shows 2 layers (top and buttomn), I do not know if PCB Editor provides auto routing fore more that 2 layers or not? if yes how can I define auto routing fore other layers?:|

I appreciate your time and response

You need to tell us what software you are using. Each EDA software has its own way of setting up routing and placing components.

Not needed! we have to guess what software this person is using. I bet he is working for one of those so called "design services" that charges cheap rates. Is scary to see that they through designs at people with no understanding of PCB layout processes and tools.

There are dozens of different PCB and Schematic editors.

Cadence Allegro, Orcad, Mentor PADS, Altium Designer, Protel, Pulsonix, Eagle, PCAD, Cadstar, etc, etc...

In addition to the various brands, there are different versions. For example, Allegro 14, 15, 15.2, 16, 16.1, 16.2; Altium DXP2004, Altium Designer version 6, S08, W09, S09; Protel 2.8, 3.1, 98, 99SE; etc, etc...

Within the Cadence versions there are various implementations. For example, Allegro PCB Designer XL, Allegro PCB Performance Option, Allegro PCB Design L, and PCB Designer.

Since you are a beginning student, I think you need to start by running the tutorial that comes with the software you have. The tutorial is intended to answer basic questions regarding the use of the software. Once you have learned the basics regarding how to run the software, you'll be able to get the finer points explained here.
