  • Unable to see changes to PCB in real time

    Hi all, I am having quite a puzzling bevahoir withmy 16.3 Allegro PCB editor. Whenever I open my board file and I try to do any changes to it, i.e. move a component or route a net, I do no see the changes happen in real time. Normally, when I was working with a PCB, I could select parts and move them...

  • Re: Cut outs In PCB

    I show slots cut into the board on the board geometry layer with the appropriate notes. In your case, show the slot and add the note(s) regarding the depth of the slot. Note: This will increase the cost of the boards since they can only route one at a time. If at all possible I would route through the...

  • Can't move small jogs in trace into pad

    Since upgrading to Allegro 16.3 I have not been able to find the feature that allows me to move a small 45 degree angle in a trace between two component pads into the pad itself. For example before version 16.3, when I had two pads that were not exactly in the same "Y plane" that need to be...
