I'm wondering exactly how height mechanics work in 3D Grid Battles.

Specifically, do grid elements of a specific height block Line of Sight?

For example, if I had a unit directly behind a 1Y high cell on a grid, and an enemy unit directly on the opposite side, would my unit be able to target the enemy with a ranged attack?

The same goes for specifying parameters for certain area abilities (for example, a frontal cone attack would not target cells above a certain height).

If this is not possible, can I add it myself using something like raycasting or lines?

The Check Height Differences settings are used for that in your grid shape settings. You can define if and how cells are checked for being above or below a cell.

Line of sight only checks for cell state stuff, like blocked, occupied, etc. - e.g. this can be used to not have cells behind combatants (from user's perspective) be targeted.

Is there a way I can add this? I'm only using flat XZ 3D isometric square grids (kind of like Tactics Ogre).

For example, if I could write an editor script to set a height field for each cell based on the Y transform of the cell, then reference that variable elsewhere using ORK?

You can probably use the Variable Conditions for the grid shape. Grid cells can use object variables (can e.g. be set up in the cell type settings), e.g. using a float variable to define a height parameter.
