You can't directly convert AutoCAD 'Points' into a Revit surface. But you can convert the AutoCAD 'Points' into a csv with XYZ coordinates. Seems that contours come out a little smoother but if this is all you got it's better than nothing. Here's how...
Open AutoCAD file which contains 'points'
Create New, next
Give Name, next
Select current file, next
Filter only Points, next
Clear Show count and name, next
Output Data to external file, choose name and csv, next
Delete header rows
Move all data rows up
Save (as CSV) and close
Create from Import, Points
