Entirely possible @patrick.kabia 
You will need to extract the ground points from your data before proceeding into Dynamo or Revit.To do this, use of external software such as CloudCompare will be necessary. Reduction in point numbers via random sampling or Octree (spaced intervals) will also be required to ensure that any Topographical element doesn’t have an extremely complex series of control points, as this will be detrimental to model performance.
It would be easier to export the extracted points to an XYZ formatted file and read that file to create your points in Dynamo.
Then you should be able to use the OOTB node as intended.
