I have a 2 layer board defined in my stackup. I have added 3 vias into the Phyical constraint set to make those via choices available for routing.
I have also configured my working layers to both top and bottom. When routing if I RMB and select add a via I get no choice to choose the via I want to use. It just defaults to the first one defined in the constraint list.
Now if I change the stackup to 4 layers and only select the outer layers top and bottom from the WL menu I still get no choice to choose a via when routing.
But if I select all 4 layers in the working layers menu and right click add a via while routing I am presented with a choice of vias to use and life is good.
Was wondering if this issue is by design or is it a bug. Seems odd that you cant choose the via you want to use via the RMB for a two layer board while routing.
