Point Group and Grade Creation Issues
Im confused. why create a point files to imports as cogo point that you want to turn into acad point to add to a surface? You know you can add a point file(s) to a surface directly right? it is actually the Best practices suggested method.
What is a "group file" made from acad points? cad point would be added as "drawing objects>> points
When you say cad points to many that is a generic acad node that can have xyz.` if you mean civil3d points they are referred to as Cogo Points
Grade point group? whats that? Grade creation tools? you mean the grading tools? are you sure you set a site?
points, point groups, and surfaces should not effect the the grading tool bar

I applaud your determination.
Unless you absolutely need the cogo point I suggest you forego the DATAEXTRACTION to avoid any potential errors. Not sure why your surveyor would not give you a point file ?
Here's the thing if you extract the pnezd and build a TIN and its wrong - thats on you. if you build a TIN from the Contours the surveyor provided and something goes wrong at construction - thats on him.
the surveyor gave you a nice set of 1 foot contours, build your surface from the provided polylines. It took me 15 seconds to create the surface from the provided poly line.
Note: of all the points in his field you do not know if he excluded any in his contour development.
I still stand by my first advice if you have a point file, add the point file to the surface not the gogo points

I get that your learning and im not trying to make you feel bad im just sharing my experience with you. We all started with this software exactly where you are at, you are in the right place for questions and answers.
Yes Dataextracting his spot elevation labels would be similar to "receiving" a point file except when the judge says did you receive a point file from the surveyor? you cannot answer yes and the judge could give a rats tush about DataExrtraction or Youtube.
Youtube is a wonderful resource for learning the software I'm sharing with you my knowledge of potential liability; youtube wont tell you that.. yes points are are fundamental building block but there are others. I am also sharing an efficiency workflow that your employer would appreciate.
Yes unfortunately some surveyors will try to hold you over a barrel. are they working for the same client?
Lets look at the workings of a surface:
if you expand the surface collection in toolspace you see the image below. every surface has the same exact collection. I highlighted the ones I feel are fundamentally important to understand. In no particular order
Boundary : can be a user defined closed poly lint to control the limits of triangulation (often best to add last)
Breaklines: physical objects to add where discontinuity occurs; curbs and walls...(often feature line or 3d poly lines, special break line called proximity can use a 2d line)
Contours: 2d poly lines with elevations ( can be drafted of inherited from other sources)
Drawing objects: pretty much any native acad object (*)
Point files: ( csv files of various formats can be added to surfaces directly) (**)
point Groups: ( cogo grouped together)
* right clicking each type in toolspace allows you to add to the surface definition
** it is true if the surface is disconnected from the file there would be a problem but this is the best practices suggested use over creating the cogo points "in the surface file". it a performance thing. some surfaces could have thousands or millions of points, putting that many cogo in dwg would crush cad
explore each of those components. you will find it enlightening
