[Resolved]  Cannot route to an arc?

rickford66

I have an application in which the board must be in a circle, and I need to route around the circle, connecting different routes to said circular route.  Problem is, the ratsnest won't connect to the middle of a route if the route is in the shape of an arc.  This is true if I draw an arc directly, or if I use route and shape it as an arc.  What gives?  How do I do this?  Thanks.

    Hi

     

    It's possible. See the attached. You may not get the attachment at

    Element14 (their problem to fix ) so view it at EagleCentral or the

    news.cadsoft.de if needs be.

     

    Forget about the circle arc until the end.

    From the image you can see it finished at 9-11 oclock and 4- 7 oclock

     

    I suggest placing a reference circle, which you can delete later.

    Start out with straight lines as shown between 12 and 4 oclock. No need for

    precision at this point. If you forget a stub trace to a component its easy

    to attach it now with the CTL key and ROUTE selected. the trace will

    attached as you know. Later you will have to remove the curve from the wire

    to do it but its easy. Just get the information for the curved trace  and

    change the curve to zero.

     

    Once you have the basic layout as straight wires do the folowing.

    First make your alternate grid the finest.

    Then move the intersections of the stub traces and the (to be) circular

    trace to the point on the circle you desire, Use the ALT key for the Alt

    grid to place with precision.

     

    Looks like 3-4 oclock

     

    Now to create the curves. Select MOVE, hold CTL and select between the

    stubs and depress ALT to place with precision. Job done.

     

    All the best

    I don't see the example you speak of, but I think I kind of understand what you mean.  I'll play around with it and see what happens.

    Thanks.

    I got it to work using your method.  That's a very strange way to have to do it.  Seems like you should be able to just put an arc around the thing and connect to it.  My last PCB program didn't allow that either.  I wonder if there's some reason for it of which I'm not aware.

    Anyway, thanks for the info.  It helped a lot.
