I have a connector symbol that has two mounting holes. I want to have an area around the mounting holes where there can be no other components. On the bottom side there shall be no traces, but traces are allowed on the top side.
I have tried many different keepouts and the only errors I ever get are for vias or traces inside the keepout area. I can put a component in there and don't get any error.
I have tried:place outline, Route Keepout, Package keepout, all will allow me to place a part within the keepout area.
Tom - your concept of the usage is correct. I suspect you've already experimented with top/bottom/all with the placement/keepout boundaries? If so, it sounds like the check has been disabled.
Go into Constraint Manager, click on Analyze, Analysis Modes, Design Modes (Package) and see if everything is on.
