Modify default fencing types

[10boomer]

OK, I admit in advance that what I'm trying to do is probably easy and that I'm simply mission the obvious.... but here goes...

I need to place some fencing around a garden..... when I do so, I get the typical white picket fence....which is pretty, but not what I actually have in place....

I would like to modify the fencing to a 7' wire fence (material they call "Goat Fence", 2x2 wire fence, 4x4 wire fence, etc.).

The fencing is held in place by regularly placed wire fence posts (basically a triangular profile that does not provide much in the way of lateral stability.... rather it just holds the fencing up in the air..... stability is provided by larger and stronger galvanized end-posts.....

so with all that said, is there an easy setting to change height and material to what I need?

Thanks in advance.....
