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'
Type DATAEXTRACTION
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
Finish
Open csv
Delete header rows
Move all data rows up
Save (as CSV) and close
Open Revit
Toposurface
Create from Import, Points
Select CSV
Select Unit
