.NET Framework error when renaming a terrain model

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.

Geopak SS3 .722.

  • Hello Derek,

    Would it be possible for me to get your data set? I can email you a link to my Bentley Sharefile.

  • 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:

    ************** Exception Text **************

    Using Geopak SS4 .878.

  • Same error again. This time, no edits were made to any element. I right-clicked an entry in the Civil Data list with intent to zoom to that feature. I wasn't going to have that option because the active model was a plan model. So I zoomed out in the 3D model and this error came up. The terrain I had right-clicked was still selected, and the element information was still shown.
  • I got the same error on Geopak SS4 .878. This time, I was in the middle of creating a new dynamic cross section view. I got through the step of setting the alignment, left offset, and right offset. In order to specify the location along the alignment, I was panning the view by zooming out and zooming in, moving my cursor in the process. Without clicking my mouse button, this error was raised.

    This file is pretty big, so it's probably unreasonable to send it.
