i have 32 and 64 bit installed (64 for waterfox, but others tend to use it)
If it helps, I got the fence to work before but it needed an ugly addition.
here, ("O" is post, "x" is blank, "l" "-" are bars)
x x x x x
x x x x x
x x O - -
x x l x x
x x l x x
fix,
O x x x x
x x x x x
x x O - -
x x l x x
x x l x x
do you see the O top left? That virtually creates a 5x5 square instead of a 3x3 square, which centers it correctly. The extra O will not blend in, and especially in my design, it will sit on top of the sloped corner.
Paul, I like your idea about underground blocks. If you can get that to work without hindering blueprint editor ease, I bet it will work great!
Aside- It took me about 10 minutes to get the code correct. I hope you guys have "Lucida Console" font (native in xp notepad)
