Diagrid Structure Problem with attachment

Dear All

I have created this simple diagrid structure using arcs and shift list to create the bracing diagonally. it all worked fine except the unwanted base members at the bottom of the structure spanning across the base width.

Would anyone be so kind to point out what I have missed alone the way?
Attached is the GH and .3dm files for your reference.

Many thanks and kind regards

Try to use “Relative Item” instead.
