Forward annotate an updated schematic

Hello,

 

I am new to Eagle. I made a schematic and generated a layout. After

arranging the components and doing part of the routing, I realised I

had to connect the jumper pins. So I went back to schematic and added

2 jumpers & connected the signal wires. In the PCB layout, I found

the 2 jumpers pads but not the airwires.

 

Is there any way to get the air wires in the PCB.

 

Thanks,

Arvidn Gupta.

First, on the board perform a RATSNEST

If that does not make the airwires appear then move over to the schematic.

The probable cause is the NETs are not connected to your jumper.

Perform a move on your jumper part. If the nets dont move with the part that

is you problem.

Ensure you use NET and not WIRE when you connect parts.

All the best

Yes, That exactly is the problem. When I move the jumpers in the schematic, the wires dont move. Also, I had used wires instead of nets. When I tried to replace them wih nets, after doing so and checking their property, it still was showing "wire" only. Pls. let me know how to convert the wire to net and if there is any way of fixing the net/wire to the jumper (I tried by double left clicking, it did not work).

Thanks for replying,

A net is a wire on the nets layer so it will appear as a wire in the

properties and lower down in the properties you will see it has a net name

like N$2 for example.

Net has a bit more automation attached to it so drawing with net will be

more successful.

The schematic and all devices you add to it  need to be created with a grid

set to 0.1".

In that way the pin connection points are on the grid and so your net will

attach to the pins reliably .

If your device has been placed off-grid, select it with the CTL key

depressed and it will jump to the grid.

The last advice is to start the net connection at the jumper device first.

The net should snap to the pin and connect .

All the best
