I'm confused about adding NETS

jeffm5457 Level 3

I'm confused, should I be using the Wire command to connect components in the schematic or using the Net command. One tutorial says use wire, another says use net. I tried a small schematic using both and then converted the schematic to a board and all wire showed up. I guess I don't understand the difference. Any help would sure be appreciated because I think i am trying to make this more difficult that it should be.

Thanks,

 

Jeff

    Net is for the electrical connection of parts, Wire is intended to draw

    graphical stuff like borders for a partial circuit etc. The name is

    ambiguous, also the layer 91 used for it.

    The behavior is different from Net, so try the following:

    open a sch

    add 3 resistors (see screenshot "wire-tool")

    use the Wire-button & connect R1, R2 & R3.

    You will see:

    no auto-junction, no auto-end of the wire, only 2x click will end the wire.

     

    Now use the Net-button & try the same (see screenshot "net-tool")

    You will see:

    auto-end of the net & auto-junction

    Excellent explanation. Cadsoft should use it in the tutorial, with your

    permission of course

    THX,

    You have to learn this when teaching eagle in a technical school in austria

    ( if you are interested in other documents: www.htlwien10.at  schüler ->

    unterrichtsmaterial -> eagle -> dokumentation)

    Always use NET to make schematic connections.

     

    The command names in Eagle are perfectly logical.  WIRE is used to draw

    lines except when they respresent wires, then you use NET.

    I'm also learning - I understand the explanation and agree that for

    electrical connections NET is more convenient with "Auto End" and "dot on

    junctions" but at the end of the project is there does not appear to be any

    electrical difference in fact if I draw a new wire by itself then another

    wire to connect into an existing NET it gives the option of using the new

    Net$ name or adopt the name of the N$n to which we are connecting.

     

    So in summary it would appear that if I had earlier in a project used wire

    then I don't need to go back & redraw as long as the N$n ar correctly

    connected.

     

    Well that it how I see it and welcome comment.

     

    This was an excellent question to be raised in the first place.

    touche! That's good, Olin.

     

    Jeff, Also be advised that CUT doesn't cut - it copies.

    over the day it didn't work (server breakdown?) but now it works again. I'm

    sorry you cannot open the folders, they are at the moment only for teachers

    & students (login required). I'll talk to the webmaster maybe he can make a

    change.

    Thanks for the info. There is really lot of information about

    EAGLE.... Well done, thank you!
