Railing Misplaced

[Ringos]

On the foundation layer, I drew the deck on a sloped terrain using a retaining wall because I could not figure out how to put a stone face on a slab. It seems you should just be able to go into materials and add a stone material to a face.

 

Regardless, Then I drew a slab with stone material for the deck.

 

However, I cannot get a railing to set on the deck. They are either too high or too low. It seems like there should be an elevation setting.

 

I need to understand what is going on.

You need a "room" for your deck/patio/porch...which appears you do not have. The railing is a wall and the bottom is most likely sitting at the elevation designated for the "foundation" level. 

 

Create a room using the railing by attaching this to the house. Once you have a room...you can designate what type of room, you can then control the floor construction etc.
