I've got a complex terrain model I'm maintaining in PowerInRoads V8i SS10 on a Windows 10 machine. Upon opening the dgn, I get the following error:
I've reinstalled the .Net Framework and scanned the registry for errors.
Any ideas?
This is a common problem in the SS4 product. It generally means the file is corrupt. Have you tried the "civil display browser" key in and file fixer? There is a repair button in this dialogue. A word of caution though, it is almost certain that this will break some relationship in the file since it is this same relationship that has been corrupted.

An Object is an instance of a Class , it is stored some where in memory. A reference is what is used to describe the pointer to the memory location where the Object resides. The message "object reference not set to an instance of an object" means that you are referring to an object the does not exist or was deleted or cleaned up. It's usually better to avoid a NullReferenceException than to handle it after it occurs. To prevent the error, objects that could be null should be tested for null before being used.
if (mClass != null){ // Go ahead and use mClass mClass.property = ...}else{ // Attempting to use mClass here will result in NullReferenceException}
Hi Malcom, I having this "object reference not set to an instance of an object" problem. Where I can find the text file to insert these lines?
