Didn't see this posted anywhere so is a copy of the original guide:

Main Elevator blocks:
VCZ Elevator Rotor Base - Main ELevator block that goes at the bottom of your elevator. Use VCZ Elevator Middle or VCZ Elevator Middle Double for your first floor instead of VCZ Elevator Bottom. First floor can have Fillers or Filler Vent between it and the Base.
VCZ Elevator Rotor - Main Elevator block that goes right above VCZ Elevator Bottom. This is the old way to build an elevator and is useful if you don't have space under the first floor.

Floor blocks:
VCZ Elevator Bottom - The block for the first floor if you are not using VCZ Elevator Rotor Base;
VCZ Elevator Middle - The block used for any other floor between the first and the last;
VCZ Elevator Middle Double - Same as VCZ Elevator Middle but 2 blocks tall for a floor level with half blocks;
VCZ Elevator Top - The block for the last floor;

Filler blocks:
VCZ Elevator Filler - A filler block to place between floors.
VCZ Elevator Filler Double - A 2 blocks high filler block to place between floors.
VCZ Elevator Filler Vent - Same as above but also works as an Air Vent.
