I cannot open the Corridor Objects tool (Bucket Icon) so to modify a corridor I have to use the Properties dialog box selected from the Project Explorer.
I was trying to change the stations for a Parametric Constraint but when I would edit the station I would get a Property is not Valid dialog box with Details of Object reference not set to an instance of an object.
Next I tried to simply change it from Enabled = True to False and the same thing happens and eventually the MicroStation has stopped Working dialog box opens.
How can I recover a working and editable corridor from this file?
Why can't you use the Corridor Objects tool? Does it work for none of your corridors, or just that one?
Have you tried turning it off and back on? using the key-in "civil display browser"? That might fix the problem of the Corridor Objects tool, and it might solve your most immediate problem too.
Or, as my mom says, it might cure what ails you and might help besides.
