Using Allegro 17.2
Are routing differential lines and need to change layer. Allegro sets vias but they will always be aligned horizontal in respect to each other and thus changing direction when routing horizontal.I guess this is a simpel setting to correct but I cant find where. The image below describes the problem better than words. The orange arrow shows my routing direction when i click to set via. Then the vias are set as seen on the right image (marked wrong). What I would expect to happen is shown in the image to the left (marked "OK"). How do I accomplish this?
in routing mode right mouse click and click on via pattern. click vertical
