I realize OP posted this quite some time ago, but in case anyone else stumbles upon this thread. I believe this is SketchUp's 3D Warehouse. I dont know why it doesnt pass credentials through. The only thing I can think of is that this is a result of the fractured ecosystem that they inherited, and they wanted to get sketchup licensing moved over to Trimble accounts as fast as possible, and 3D Warehouse was put on the back burner. I believe you can have accounts on both services that share a primary ID, but are unique from oneanother. But that is just a guess.
