Hello Luqman Liaquat

You need to define your pile as different groups with different groups along the same length ( for example from z=0 to z=-10 group 1 and from z=-10 to z=-15 group b ). The part you intended to cut is a different group with a different name. However, when you want to cut or remove that part you can use the following code

zone delete range group 'group b'

Hope this answers your question

Let me know if I can help more

While connecting the piles through nodes, it is difficult to have interaction between interface. Moreover, it will increase your work.

Abhishek Sharma , yes brother you are also right so i create two piles with same id it will be convenient to cut pile and@ no need to connect by node to node....
