Is there easy way to get XYZ,IJK, colour data to make 3d mesh in ploty studio chart?

Is there a free software where i can simply drag and drop plot that will generate X,Y,Z values to form objects then export into csv/excel file format? I need the data (X,Y,Z , I,J,K) so i can import into plotly studio .

I am curious how people in the plotly community were able to make lot of 3d mesh object and the helicopter object in the tutorial : 3D Mesh Plot

Where do people get these data from?
