My company has finally decided to upgrade from Civil 3D 2008 to Civil 3D 2012. I wrote a few custom .net subassemblies in 2008 that I need to migrate over to 2012, and I am just trying to estimate how complicated this is going to be before I begin. I'm just wondering if Autodesk made any major changes to the way the subassemblies are written that would prevent me from just copying the older code in and recompiling? Any help would be appreciated.
Some of the corridor objects changed, but the strucure stayed pretty much the same. I think it took me about 2 hours to upgrade the last time I did one. I spent most of my time remembering how to set up the import files.
