How to build custom wood support in planet coaster

This is a tutorial on how to make stuff out of wood, mostly supports but you can do whatever you want, it's your wood...
I forgot to talk about the round wood supports. You can build with them pretty easily, they are in the buildings/decorations/other section, or just search for "log".
This tutorial covers (in no particular order):
Removing game generated supports
The different types of wood beams
The difference between a wood and a paint finish
Preventing Z fighting
What to use as footer
Other ideas for wood structures
Me having wood, in the game of course, not making a pun here

For those who are just looking for the location of the pieces:
All of them can be found in buildings/walls/columns
