Prevent/detect traces that hit a pad off-centre

#1 Post by greiginsydney » 28 Jan 2025, 22:45

Hi All,


I always manually route my boards, and sometimes end up with a track that ends off-centre in a pad. I've attached an image of exaggerated example of this.

(Worse ones enter the pad's boundary off-axis and then bend 45° to terminate in the centre).

Is there a setting I've missed that lets me force traces to always land centred? (I'm guessing not because that would potentially violate 'snap to grid').

Alternatively can the DRC bring occurrences of these to my attention, so I can manually correct them?

Thanks,


- Greig.

Use S hot key when you route traces manually and start/ route/ finish the trace.It toggles between few presets how two last segments are configured regarding to previous click and current cursor position. It will help to finish the trace exactly as you want.

Thanks Alex.

That only seems to cycle through a lot of unwanted options (e.g. curves & direct 'as the crow flies') rather than my requirement for 45° corners and traces that land directly in the centre of the pad - but I've learnt something in the process.

Is the better approach to click on the start and end pads and then manually adjust the routing afterwards, adding N(nodes) where bends are required? I've historically started at the source and clicked my way through to the destination, but every so often with a fine grid my end isn't always centred.
