How do you define and edit areas which you wish to display contours on?
First, you must create a surface using the Create Surface command under the Surface tab. Then, as Erik mentioned, use the Quick Contours or Create Contours commands to generate contours on that surface. If you wish to edit the area where the contours are generated you will have to edit the surface boundaries which can be done using the
Here is a YouTube video that goes over some of the common Surface/Contour tools: surface tools and volume calculations - YouTube

For example, I gather data for a stockpile but also get data around the pile. When I create the surface it will have data outside of the stockpile that I don't want to use in my contour or volume calculations. I can create a surface boundary around the stockpile toe using a CAD line or linestring which will limit the surface to enclosed area. Now when I generate contours they will only be created within the surface boundaries.
