Altium: Routing in different layers brings me back to top layer

Routing on the top layer is fine. But whenever I try to route on a different layer, it automatically brings me back to the top layer and routes there. Am I missing a step? Let me make this more clear. 1. I can move from one layer to "next" using…

Altium: How can I dim the layers I'm not currently using?

The routes on all layers are fully bright. I want to dim the ones on the layers not currently used. I don't mean dimming ALL routes (even on the layer I'm currently on) except the one segment I'm selecting.

Altium: the shortcut key +/- don't move me to the next layers

I have created multiple layers from the stack layer manager. Also created vias from layer 1 to 2, and 1 to 3. When I clicked okay, the layer image didn't get updated, meaning it didnt add the vias I created (not sure if this is normal). My guess is…

8-Layer Stackup question

Alright. I was given the task to design an analog design board which contains lots of opamps, some CMOS switches and some ADCs/DACs. It also contains 4 separate power supplies (each supplying +5V and -5V (+5VA1 .. +5VA4, -5VA1 .. -5VA4,…

Separation between signals control tracks and dissipation of heat in a PCB with 4 layers

I am designing an SMD PCB to control two motors that consume 6 A each. I have too many components and I am using 4 layers, so I want separate the tracks. I have found out that the tracks with high current must be in a external layer. I have been…

Can't delete a rigid/flex substack from altium 19

so I've recently been learning altium and I'm one of those learners who tends to click things to see what they do and then figure out how to undo it afterwards. Unfortunately I've now run into a problem with that method because at some point I…

Has double (green) protoboard benefits when using this way of soldering?

I'm intending to use the same soldering 'technique' as in the picture below (just an example), by using wires and solder connections. I am wondering if it has benefits by using the green double sided protoboard (I have quite some of them), or using…

Eagle Freeware - definition of 'signal layers'

According the the Cadsoft website, Eagle Freeware supports '2 signal layers'. Am I right that Cadsoft includes power and ground layers in their definition of 'signal layers'? In other words, am I right that Eagle Freeware doesn't support 2 signal…

Does layer order matter on multi layer PCB?

I have a 4 layer PCB with the following planes... Connector (Top): Holds all traces going from connectors to components. Signal Ground: Coper filled completely. Power (Bottom): Coper filled for +15V and traces for -15V Does it matter if the bottom…
