In this chapter, you started writing the excavation planning manager, code named Yharnam. In the first part of the chapter, you spent time learning to use the geodatabase editing and preparing the project. You then learned how to use the rubber band tool, which allows you to draw geometries on the map. Using this drawn geometry, you edited the workspace and created a new excavation feature with that geometry. You then learned how to view and edit the excavation feature with attributes.

In the next chapter, you will keep enhancing the Excavation Planning Manager to add more functionality to it. You will work on how to do advanced spatial operations on other feature classes to obtain the cost of an excavation.
