Hi Ali,

there are plenty of solutions for that very or similar tasks on this forum. Here is the first one apperared via Search tab in the upper right corner. :slight_smile:

Dear Jakinta
Thanks for your response. The Link was good but my case is different. I work on surfaces not the Brep.

Not correct. The case is exactly the same. Box is a Brep and what is a Brep than a collection of surfaces?! When you explode a Brep, you will get surfaces and then you can sort them via Z-coordinates…
or you can just extrude rectangle(curve, not a surface) and you will get desired surfaces without any exploding/sorting.

Thank you Jakinta
I try to use it, Please kindly look at the file I really confused and I don’t know what’s wrong?
