Eagle ver 6.3 - how to clear vias?

Currently using Eagle ver 6.3, after almost 3 years.

The most pervasive difficulty (at basic level): a via is assigned to change layer during a rerouting; trying to delete it later is not allowed because Eagle considers it as part of the net (do it in the schematics, it says...!)

I recall deleting a via once after a sequence of wild attempts but could not repeat the series of events.

Could anyone help me on this? Gracias.

Use the "ripup" feature, not the "delete" feature. Ripup doesn't require back-annotation, delete does (which isn't allowed in the free version).

Hope this helps!

Sure Matt. Gracias.

Ripping up was the solution. But to understand it I had to relearn how to properly change layers when rerouting (I was forcing vias instead of allowing Eagle to do it properly. Go figure.)

Gracias again.
