how can i import points from excel to rhino?
maybe you can start there
Python is not needed.
Create a sheet in Excel which only has the x, y and z (if needed) coordinates of each point. Start in the first row and first column. One coordinate per column and one point per row. No gaps. No headers or other text information. Make sure the columns are in Number format.
Save the sheet as a Comma separated values .csv file.
Use Import command to import the .csv file into Rhino.
