As I was renaming a terrain model, this nonfatal error came up. After clicking Continue, everything seems to be working normally.
System.NullReferenceException: Object reference not set to an instance of an object. at Bentley.DTM.Element.DTMNavElement.GetPropertyList(NavigatorNode nodeIn) at Bentley.DesignExplorer.NavigatorPropertyGrid.ReloadInstanceList(List`1 navigatorNodesIn) at Bentley.DesignExplorer.NavigatorPropertyGrid.Reload() at Bentley.DesignExplorer.NavigatorPropertyGrid.OnReloadTimeout(Object senderIn, EventArgs eventArgsIn) at System.Windows.Forms.Timer.OnTick(EventArgs e) at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

I've found this error again. In this case, I was in the middle of doing earthwork.
To be specific, I did Analyze Volumes--the tool that would allow me to place earthwork quantity text blocks. Immediately after the text was placed in a 2d model. The program got as far as flashing the text as my mouse ran over it, and then the error showed up.
In fact, I had to do it for two different terrain models. The error showed up for the second one in the same way.
The file I would send you is too big. I've uploaded it as a secure file. Look for a file named ew-ph3.dgn.
I've encountered a similar exception. The stack is a little bit different, but the top of it is the same. (Huh. Before I copied and pasted, it looked different.) This time I'm not trying to rename any terrain models, but it is related to a terrain model that seems like it's acting strange.
What I'm trying to do is to get the terrain model to show up in my Default view while it shows up fine in Default-3d. In Default, I have all levels on but it's still not showing up even though contours, triangles, and other things are all on. There is no visual trace in Default, though as I said, it's showing up fine in Default-3d.
Here's the stack:
