Drawing wire on a layer

autodeskguest
autodeskguest over 16 years ago

(using 5.7.0)

When I draw a wire between two points, it seems to connect to airwires at

the end, even if there is no net/smd on that that layer in any of the wire

ends. (If there are two different airwires at each end, it refuses to draw

the wire.)

I agree it should connect to the airwire if there is a pad/via or net/smd at

the same layer you are drawing, but I think it should start a new netname if

there is no natural connection.

Am I missing some advantages the way it is done now?

 

[In addidtion, I think this connecting should also happen for every wire

when you paste stuff over existing airwires... Or at least ask you if you

want to do that]

    First, imagine if you have two different airwires at the same point (at

     

    different layers). When you draw a wire (not route, but wire!) it will

    hook up to one of them. Uless the wire you draw is a continuation of an

    existing wire or pad, it just connects to one of the airwires (I do not

    know

    wich one it prefers). What I try to say is that in the case your wire is

    not

    meeting any other wires or smd's, it should not hook up to the airwire.

     

    This still isn't making much sense.  I guess you are in the board editor,

    but why are you using WIRE instead of ROUTE to draw copper traces?

    Whenever you click on something and there are multiple options nearby,

    I've

    always seen Eagle highlight one of them, then right click cycles thru the

    available ones, then you left click to confirm the specific choice.  What

    happens when you use ROUTE?

     

    Every time you comment my stuff, you are teaching me to do things YOUR way..

    Please stop that image I know just as many tricks that works for me as

    you probably do for yourself.

     

    I  used this to strengthen some polygon fills. The general spacing I use

    doesnt make the fill between some via's, but I accept some smaller clearance

    at some places, and therefore use wire's between those via's (and rename it

    to whatever I want) to make the airwire disappear (after ratsnest). You may

    discuss the correctness of this, but I'm not interested in hearing right now

    image

    It can be fixed by not drawing a wire between airwires, rather move the ends

    after drawing, so its not a dead critical issue, its just not right, and

    thats why I posted this.
