Need Help with Allegro PCB editor 16.2

HGarcia

Hello Everybody,

I need help for a PCB that I'm routing in Allegro PCB Editor 16.2. I'm routing a BGA breakout using arcs, but these arcs have to be with a specific raidus. I tried to use arcs w/radius and the arc generated appears in etch subclass but not as a Cline, because of that I couldn't connect it to a net. Also, I tried to route using arcs but I couldn't get the specific radius what I need. Is there a way to change lines to clines? or how can I route to get a specific radius?

 Thanks a lot.

    Hector,

    You should be able to just add a cline to the pad and route it with the arc.  There are several ways to do this:

    1) Add the arcs in the symbol (see zip file attachment)

    2) Add the arcs in the board (see zip file attachment)

    Once the arc has been added you can always modify the arc with the "Edit->Vertex" command. See attached BMP screen shots.

     If this does not help ask again!

    Is it possible in Edit -> Vertex to use ix and iy commands to get an exactly radius from an xy origin? I want to make a routing like the image below

    They are diff pairs into a BGA and the way to get the breakouts is with arcs. I could do that using Add -> Arc w/radius to avoid spacing DRC's and was made as a line, how can I make this arcs as Clines?

    Thanks a lot for your help.

     Regards.
