Hi all,

I have two csv files. One contains data for only one z plane and the other contains data for 41 z planes. I am using TableToStructureGrid Filter to get the domain from CSV file.

I also checked the number of rows. The first CSV file has 67312 rows while the other has 67312 \* 41 = 2759792 rows. I have also arranged the rows by ‘y’ and then ‘z’ for the 3D CSV file. Still, I am getting the following results:( Pics attached)

Could you please help me in figuring out why those horizontal black lines occur for the 3D csv files?  
Thank you

What are the dimensions of your volume, and what is the Whole Extent you have set?
