Although I have been an occasional PADS layout user for many years, all my previous projects used netlist flow. My current project is my first attempt to use DxDesigner with the integrated flow to PADS layout.
I have two via types defined, MEDIUMVIA (40 mil pad, 25 mil hole) and TINYVIA (25 mil pad, 15 mil hole) in addition to STANDARDVIA. Both are "through" vias. However, after I select one of these two vias for placement (RMB->via type) when I place a via while manually routing the resulting via is always of type STANDARDVIA. Furthermore, if I select a previously placed via and then try to change its type via the properties window to either TINYVIA or MEDIUMVIA, the attempt fails and I see "Violation detected" on the message bar at the bottom of the window.
I'm guessing there is some sort of constraint issue, but I can't find a seemingly relevant constraint. I would appreciate suggestions as to how I might resolve this problem, as I am currently stuck.
