Hi Marshall, The "connection to overlapping split planes" message often relates to a via or pad that is connected to one of the planes, but is located too close to the plane boundary ("too close" being a function of the design rules in force). The error markers from a full DRC usually highlight where this is happening. I've not seen the "intersecting board outline" error before, so I can't help with that one.
