Title: Route trace where I want it - with no airwire.
Post by: FeralCl on April 12, 2018, 04:53:34 pm

I'm laying out heavy power and grounds on a PCB with several connectors each with VCC and GND.

All the connectors currently have at least one VCC and GND trace. The final trace is VCC between two adjacent connectors but there is no airwire.

Running "ratsnest ! *" followed by "ratsnest VCC" reveals airwires between VCC,  pullups, bypasses and connectors making the layout electrically correct but not what I want.

I could temporarily move components and run ratsnest until an airwire appears where I want it but there must be a better way.

Can anyone suggest a better approach?

Activate the "route" command.
Keep the Ctrl-key pressed.
Left-click on a trace or pin/pad.
Release the Ctrl-key.
Layout the new trace.

Thanks, Karel! I had not been aware of that one.
But you forgot the "Let me know if there's anything else I can do for you."  ;)

Well that seems to work pretty well, and the now redundant airwires disappear too.

On a Mac it's the command key not control.

Thanks very much Karel.
