I am having issues with certain functions within AutoCAD Civil 3D 2013. I am using a Mac but running CAD on Windows 7-64 bit operating system through the program Parallels Desktop. Whenever I try to view surface properties, Civil 3D crashes. I can edit the styles and add/remove information from the surfaces just fine, but I need to access surface properties so I can make Isopachs. Is there anything I can adjust to prevent this from happening?
