HELP PLS, updating board from modified sche matic

I'm having a problem. I have made some changes in my schematic and now get

consistency errors between my schematic and the board. I thought it would

update the board.

It does that quite well, but ONLY if you have BOTH editor windows

(schematic AND board) open at the same time. Working with only ONE

window destroys consistency and creates the mother of all headaches.

Its a really complex design and don't want to have to delete the board and

replace the bucket-loads of components again. Is there a way to update the

board from the schematic??

No. Once consistency is destroyed, you are on your own and need to

correct everything manually. But one CAN do it manually - even if it's a

pain somewhere:

  1. The ERC displays lots of inconsistencies telling you what is

     missing on the board, what is connected to different signals,

     etc.

  2. Look at EVERY SINGLE inconsistency and either retrace your steps

     in the schematic, or add signals in the board, or do whatever is

     necessary.

  3. Sometimes one problem may be displayed as several inconsistencies,

     so the number of actual problems might be smaller than shown by

     the ERC.

  4. After EACH change, run an ERC again and look whether that

     problem has been solved. If not, try again.

Unfortunately, EAGLE does NOT show any warning in case one continues

working with only ONE window, so one can only prevent inconsistencies

(and ruined projects) by REALLY paying attention.

Hi Andreas,

In the next version we will have an indicator in the GUI to let you know

when consistency is broken.
