How to create simple earthwork by placing the points and calculate cut and fill using Revit 2019

Описание: I am a Quantity Surveying background, an educator, a certified Revit Architecture user, and not a pro Revit trainer.
Thank you, BandiCAM.com, for making me easy to teach my students and create this video to share with my colleagues.
At first, this is for internal sharing, but I think it will be great to upload it here for everyone to watch.
It will not be a perfect video, but I hope these could be improved for the upcoming videos in the future with your constructive feedback.

credit to Dr Azeyah for the earthwork plan.
And thanks to Dr Celine too for making me to do this!

sorry for the noise in the background
