I'm working in Sketchup and I just did an intersect/match (I think the match caused the blowup), and now my model is stuck in wireframe mode. None of the "render by" mode buttons do anything.
I shouldn't have to backtrack far as I've been saving regularly, but it would be nice to know why this blew up, because I'm going to have to intersect and match again after I redo the changes...
Here's a copy of the osm file:
