No Airwaves on Changed Parts

e14 Contributor

Hi there. I'm back using Eagle after being away from it for 5 years. I've got a problem that I just can't seem to solve. I designed a board and had it manufactured and then discovered there were some problems. Starting from that original design, in the schematic I deleted 3 parts and replaced them with different ones. I changed some of the wires as well. The schematic looks good but when I go to the board there are no airwaves going to the 3 new parts. All the other components are still connected. I could really use advise on how to solve this problem.

Thanks much, Justin Mayer

    Hello Justin,

     

    It seems that the parts only look to be connected, but in reality are not. 

    Try to pick up one of the changed part in the schematic and MOVE it (F7). 

    Do the nets that should be connected move with it? Have you run ERC?

     

    I could be useful if you told which version you are using.

    Thanks so much for getting back to me Richard. I'm running Eagle 6.3.0 Mac. You are spot on! They aren't connected. I wonder why? I have been having some strange connection problems that might be caused from changing the grid resolution around but I'm not sure. Isn't there usually a little sound that the computer makes when a connection is made? Then again I'm using a new part that I designed. For all I know there's something wrong with it. But I am now having problems with a connection to a resistor that I didn't before I changed the grid resolution around.

    Any ideas?

    Thanks again. Justin
