Video is basically related to
Creating Contours, Creating Surface, Generating Alignment, Creating Profiles, Sections, Calculating Cut and Fill Volumes.
I learnt Civil 3D for Hydropower Designing- Fixing Waterways, Penstock Trench Cutting and Filling, Selecting the best alignment.
PS: Other digital terrain modelling can be used but they are a bit permanent in nature and we should use them with software like AutoCAD. We can use them for general purpose.
Once you learn how to use Civil 3D then you will not regret. It is quite difficult in the beginning.
