Placing vias

autodeskguest

Hi,

 

I'm routing a double-side board with off-grid parts. I'm using the

finest grid beacuse the layout is very simple with straight lines.

 

When two traces overlap I place a via to connect each other. EAGLE

connects only one trace to the via, the trace on the other layer won't

be connected.

 

In fact, the overlap will lead a connection when the PCB will be made,

but for EAGLE it won't.

 

How to force a connection between two overlapping traces?

 

Thank

Marco / iw2nzm

    only be used to join tracks on different layers that have the same

    net name (i.e. clock)

    Are you by any chance laying out a board without a corresponding

    schematic file?
