Deleting certain lines and areas

[damon021]

Hi there,

I am using Ansys APDL to create a model of a honeycomb grid. The size of this grid is 900mm by 450mm. However, my model is a little bit bigger. I was wondering where if there is a way remove everything beyond x=900 and z=450?

Is there any way to kinda cut the areas at these points?

Thanks in advance.

my code is here: (sorry it's messy, I'm kinda new to APDL)
