    I'm confused about adding NETS

    jeffm5457

      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,

          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

            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.
