Best way to achieve this...

I have a weldment assembly and want to add welded mesh shelves to different areas of the structure.

The areas have different dimensions so I want to simulate the way it would be cut from a sheet and welded into place.

I have made a patterned sketch with profiles, but to fit it to different areas, I have to make complex configurations of the initial patterned sketches and extrude feature values or cut the part to the sizes I need. The sheet size available is 1800x1200mm with a 25x25mm aperture and 2.5mm wire diameter.

Can anyone suggest a way to streamline this? I'm lazy.

I thought maybe modeling the whole sheet and then using a sketch and split to cut it into sections which I then save as new parts. I'm not sure if this is the best way though.
