Ok, Foul poles, almost done here.
What I do is just copy the foul pole components from previous models. I will upload this model after for anyone who wants to grab stuff from it.
Here I am copying from the Astrodome
just click on them and the ctrl-click the other one and then CTRL-C to copy
switch back to your new park and CTRL-V
when you see them they will be black and you can move them around, just get them close to where they are going and then use the move tool on each one idividually
just click on the bottom of one pole and drag it to the top of the fence until it sticks on a line at the foul line
if you are still on the move tool, you can hover over the top of the foul pole and you can rotate it if needed by hovering over one of the red crosses
