Problem of using excel data to create topography

HI all,

i am trying to create the topography form excel data through dynamo but i can not getting the topography in revit there only have some point like following:

can anyone help me on this issue? thanks

You seem to have some null values in your points list.
Avoid feeding a list with null values into Topography.ByPoints
You could do one or both of the following …

  • Flatten/Clean the Points list before connecting to Topography.ByPoints
  • Ensure that X,Y and Z have the same number of valid numeric values in the excel sheet

Success!!Thank you Vikram :grin:
