For most users one activity that must be addressed when a new version of any product is released is to understand how the user interface has changed. Where are our most commonly used commands?
Civil 3D 2010 now primarily uses a new user interface called the Ribbon. Users that wish to know where the command that they need is located have a new tool called "Where is My Command?".
We can get to this tool from either the "Help" icon pulldown in the extreme upper right hand corner of Civil 3D 2010...
or from within Help itself.
I did a search for the "Import Google Earth Image and Surface" command and was shown exactly where to find it.
The logic of the Ribbon is very user friendly and finding things the second time is very intuitive.
Be Better! ...know where to find things.
