Hi
is it possible that I connect some components(that is important for me) in Altium designer manually and then auto route the others.
I have tried but when I Auto Route, it put another track for those component and everything goes wrong.
There should be a box to tick, lock all pre-routes this should leave the tracks you have laid out and the auto touter will work round them,
When you click auto-route you will see it in the bottom right hand corner
