Create surface from 2 pointgroups

Dear all,

Good day!

Anyone, please help me to save my time.

  1. I want to create a surface with 2 point groups see attached picture for a better understanding
    example: surface name 21TOP with point groups 21TOP & 21BOT.

  2. need to know is there any chance to create a 3dpolyline from the point group, need to create a 3Dpolyline to all bottom points (point numbers are in order wise so I am doing it with transparent command but it is a repeated task I want to search any other options for this)

You want to calculate the discarded pile quantities?
as an idea
You can make a surface from all points
Outer borders have been added
Then Extract the outer bound
Then make a surface of it Calculate the quantities between them
