Forcing the same connection on multiple layers in PCBNEW

[kicad_user2]

Hi, I am using Pcbnew ver. 5.1.12.

I have a two layer board. On this board, there’s a through hole connector. This connector has two columns and multiple rows.

The columns are labelled A and B, each row is connected internally, e.g., 1_B and 1_A are connected internally.

I connected each row on the schematic as shown in Figure 1. By doing so, it allows me to lay track between each row in Pcbnew (see Figure 2).

However, in Pcbnew, I wanted to lay tracks between row A and row B on both top and bottom layers. But what happened was, after I connect row A and row B on bottom layer, and then I do the same on top layer, the connection on bottom layer disappears. It appears to restricting the connection on one layer only.

How do I force the same connection on multiple layers?

Thank you

From memory, this is the same question answered in the past:

Top Trace Removes Bottom Trace? (ANSWERED)

Hi. I am running a high voltage 240VAC line from part to part and wanted redundancy by forming a thick trace (3mm) on the top layer and ALSO a thick trace from/to the same components on the bottom layer as well. BUT when I drag a trace wire on the bottom layer from the components that already have a trace on the top layer, the top layer trace is automatically removed and only the bottom layer trace is kept. Why is that and how can I run a trace from two components on BOTH the top layer and the…

Yes, there was a setting (forgot where it was - maybe the PCB setup) that disables this behavior. Turn it off and you can create multiple traces from the same start point to the same end point.

Found it:

It’s the ‘Remove redundant tracks’ option under Interactive Router Settings:
