Hi gang,
I have a 80mm x 100mm board that I layed out & autorouted, didn't go thru 100%.
I want to re-do the layout, and change a couple of parts, go from a couple of thru hole-discrete transistors to a surface mount ULN2003 for example, move some driver parts closer to the edge connectors, etc.
The schematic has been updated. I went thru & ripped up the signals so I could move parts around so the layout could reflect the revised signal flow.
However, I can't seem to get rid of the vias that were created. I thought if I just let it autoroute it might take care of those.
Seems it did not. Autorouter has been chewing on it for a couple of hours now, the part of the board I was viewing when it started is a routing mess, it's still going, and is up to 94.8%.
Well, its down to 365 vias from over 1000 at one point, so maybe its cleaning things up as it goes.

Once it stops, how can I get rid of the vias so I have a clean set of airwire to work from for modifying the layout some more?

Thanks

Vias are deleted using the RIPUP command, not DELETE as you would expect.

Yes, I tried that, it wouldn't make them go away.
Okay, finally finished, says 89% complete, so this layout obviously needs work.

Hmm, when I select Ripup up and click a signal multiple times, the vias are going away now.
I have the view to Top & Bottom layers now.  I wonder if starting with viewing only the Top and then only the Bottom when starter the Ripup last time was affecting it?

Yes, ripup will only rip up traces on visible layers.

I didn't know that. Thanks.

BTW, ripup @; will rip up polygons, those I used for ground planes.

The Eagle autorouter is rubbish, route the board manually.

I have resorted to routing by hand, if only to better layout the components. I'm also tweaking it electrically as I go, using different paths thru an inverer chip for instance, to cut down on a lot of the crossed wires.  The faint blue "air wires" make it a little difficult to see what is going on unless zoomed, and then I can't see enough of the board to make placements that would let it route easier.
